Something has to change.

Of course, much has already changed since we last convened with our final preseason projections. But for each MLB team, playing five weeks of a new season will inevitably expose additional shifts that are needed. Every team, no matter how splendid or how dreadful the start, has something.

One thing the forecasts suggested that has borne out so far is the relative levels of stratification between the leagues. The National League, led by the champion Dodgers, looked top-heavy, and while not all of the teams we thought would make up that elite tier are a perfect match with the forecasts, the overall dynamic is very much one of dominance. Meanwhile, the American League figured to be a whole bunch of teams in spitting distance of break even, with little separation among the top 12-13 teams in the circuit.

How will these dynamics hold up until we Stock Watch again in June?

Each team’s ability, or lack thereof, to make the following changes might determine that.

Win average: 104.5 (Last: 102.4, 1st)
In the playoffs: 98.8% (Last: 97.7%)
Champions: 28.5% (Last: 28.4%)

What must change: Rotation health

There were actually some bumpy moments in the early weeks of the season for the Dodgers but nothing has happened to really knock them out of the favorite’s perch as we think ahead to late October. One thing that could change that is L.A.’s ever-growing injured list, especially its collection of 60-day IL assignments. For all the depth the Dodgers seemed to build up in their rotation over the winter, they’ve still gone with two bullpen games already. And this doesn’t even include Shohei Ohtani, who’s still building up so he can take his turns in the rotation. Given their recent history of starter injuries … maybe he shouldn’t? Including the two openers, the Dodgers have already had 10 different pitchers start games.

What must change: Middle relief instability

There hasn’t been much to complain about with the Mets. Though New York hasn’t overtaken the Dodgers in the simulations from a going-forward perspective, the Mets have probably been the better team to this point. The Dodgers have the better winning percentage, but the Mets’ Pythagorean pace (109.7) is the National League’s best. With not much to nitpick about, the relief contingent in front of Edwin Diaz needs to coalesce a little more. Ryne Stanek has the pen’s second-highest average leverage index but has struggled, and the two top lefties (A.J. Minter and Danny Young) have already been lost to injury. Still, if this is a team’s biggest worry at the beginning of May, it’s in a good place.

What must change: Ninth-inning drama

The Cubs have mostly bludgeoned their opposition so far with a breakout offense that ranks among baseball’s best in pretty much every major category. Assuming Chicago won’t average over six runs per game all season, eventually its thin bullpen is going to move into the spotlight. The Cubs have blown seven of their first 15 save opportunities. Closer Ryan Pressly has managed to white-knuckle his way through most of his outings but has struck out fewer than four batters per nine innings, with more walks than K’s. Overall, Chicago’s relievers rank 28th in swing-and-miss percentage, underscoring the general lack of dominance in that unit. The Cubs have been strong in every other facet but for them to establish themselves as a true front-runner, the relief leaks will need to be shored up.

What must change: Shortstop play

You hate to pick on Trey Sweeney, who accounts for most of Detroit’s starts at shortstop, but there just aren’t many shortcomings for the Tigers so far. No team has improved its forecast more since the start of the season. Detroit is now landing a No. 1 playoff seed more often than any other AL team in the simulations, though the Yankees’ pennant odds are still a tick better because of a higher baseline. (New York has a lower regular-season win forecast because of schedule differences.) Sweeney hasn’t hit (.234/.317/.355)* and the Tigers’ shortstop defensive rating, per FanGraphs, ranks 20th. It’s the most obvious blemish on what is shaping up as a pristine season in Detroit.

* These numbers were .202/.282/.303 entering Sunday, but Sweeney must have had spies watching over my shoulder. Against the Angels, he went 4-for-5 with a homer and six RBIs. That’s more like it.

What must change: Lineup depth

The Padres are off to a great start, largely on the strength of a bullpen that has been off the charts. The relievers have racked up 14 saves (they’ve blown only one) and 27 holds while compiling a collective 1.73 ERA. Those numbers are both unbelievable and unsustainable. When some regression sets in, a top-heavy lineup will need to get production from spots like catcher (21st in OPS) and left field (27th) to offset the difference. We kind of knew this was how the Padres were constructed, but still — San Diego has given too many plate appearances to too many players in what we’ll call the post-productive phases of their careers.

What must change: First base production

Generally speaking, the more specific the issue we choose to worry about, the better off the team. For Seattle, the primary concern the past couple of years has been more wide-lens than specific: offense. For now, that problem has apparently been largely solved. The Mariners’ offense has been one of the hottest in baseball and over the past couple of weeks, with its hitters even managing to mash at T-Mobile Park. So rather than worrying about the offense, writ large, we can point out that at first base, the Rowdy Tellez–Donovan Solano combo is mostly responsible for Seattle’s .518 OPS (tied for 29th in MLB) at the position. This projected to be a major hole before the season, so the chances of self-correction are limited. Now, the stakes are higher to shore up the weak spots, since the Mariners have emerged as the early front-runner to win the AL West.

What must change: Rotation depth chart

For a first-place team, there is plenty to worry about when it comes to the Yankees. They’ve had the best position player (Aaron Judge, by far) and arguably the best pitcher (Max Fried) in baseball. The relief staff has dealt with the struggles of demoted closer Devin Williams, but the bullpen still ranks sixth in relief ERA and with only 14% of inherited runners scoring. But the rotation has been below average (4.07 ERA and only eight quality starts) despite Fried’s great beginning. Even worse, with Gerrit Cole out for the season and Luis Gil and Marcus Stroman currently on the shelf, it’s not immediately clear how this is going to get better. This issue might really start to mushroom if and when Fried regresses from his hot start.

What must change: Slumping stalwarts

The Phillies’ roster was constructed on star power, not depth, and while that has worked well enough the past few years, they need the stars to produce. The “it’s still early” caveat applies, but so far, Bryce Harper hasn’t hit like Bryce Harper, Alec Bohm‘s production has gone missing, Aaron Nola just earned his first win but remains under league average (91 ERA+) and key bullpen acquisition Jordan Romano has gotten shelled. If the Phillies don’t want to lose sight of the front-running Mets in the NL East race, they’ll need their main cogs to start firing.

What must change: Team batting average

The Giants have inserted themselves into a top-heavy NL postseason chase that they didn’t figure to be a part of when the season began. The pitching and defense has been stellar, but the offense hasn’t kept up. San Francisco ranks eighth in walks percentage but 24th in batting average. That can work in a take-and-rake general approach to offense, but the Giants are only middle of the pack in homers. Since they aren’t very athletic and rarely steal bases, this leads to uneven production. The Giants can hang in contention with a league-level batting average, but they simply don’t hit enough homers to do so if they continue to hover around .230. That puts the onus on low-average hitters such as Matt Chapman (.198), LaMonte Wade Jr. (.141, ouch) and Willy Adames (.230 and now four homers after hitting two on Sunday) to up the ante.

What must change: Bullpen health

In what’s shaping up as a historically good NL West (save for the Rockies), little problems can quickly become big ones. For the Diamondbacks, a shiny start has lost its luster a bit as they have battled bullpen problems in both the performance and health categories. The unit scuffled badly during a 5-9 stretch, posting a 5.61 collective ERA while blowing six of 10 save opportunities. Closer A.J. Puk (elbow) is on the 60-day IL and Justin Martinez (shoulder) hit the 15-day IL after two concerning outings with diminished velocity. Both are expected to help later this season but for that to matter, the likes of Kevin Ginkel, Shelby Miller and Ryan Thompson need to step up in high-leverage spots.

What must change: Homer count

It has been a mixed bag for the Astros. Hunter Brown has been one of the game’s best pitchers and Josh Hader is having a vintage season at the back of the bullpen. The relief staff, in general, has been strong. But the lineup has been below average with a lack of power at the root of the issue. No Astro has homered more than four times and Houston ranks 21st in home run and overall slugging percentage. It’s an issue up and down the lineup but things would look a lot more promising if Christian Walker and Yordan Alvarez were going deep at their usual rates.

What must change: IL roster

An 0-7 start threatened to sink the Braves’ season before it began. They recovered — nearly climbing to .500 at one point — but they have a lot of work to do. Hopes that the Braves can still reach their ceiling hinge on the longed-for returns of Spencer Strider and Ronald Acuña Jr. In the meantime, they need underperforming stalwarts such as Matt Olson, Michael Harris II, Chris Sale and Raisel Iglesias to hit their stride. Atlanta can’t keep plodding along under .500 in this year’s NL while waiting for its stars to get healthy, but if the Braves can stay above water until then, they might be able to really take off. Considering what we’ve seen so far, the fact that they won’t see the Dodgers again during the regular season certainly helps.

What must change: Outfield production

The Royals’ offense, in general, has been missing, with only Bobby Witt Jr. producing all season. But the outfield ranks 29th in bWAR as a group — the continuation of a problem that hovered over the roster last season. MJ Melendez was sent to the minors to find himself. His initial results in Omaha suggest he’ll be searching for some time. Hunter Renfroe has produced less than a good-hitting pitcher. Mark Canha has helped in a big role and Drew Waters has had some nice moments. But the Royals need some stable offense from the corner outfielders, making this a must-get as the trade deadline starts to loom.

What must change: Emmanuel Clase

You figured the Guardians’ bullpen would fall off a bit after last season’s off-the-charts showing. That has happened even though set-up relievers Cade Smith and Hunter Gaddis have been every bit as good as they were in 2024. No, the problem has been a mystifying start by Clase, who has already given up more runs (11) than he did all of last season (10). He already has won four games, matching a career high, but of course that’s not necessarily a good sign for a closer. Clase’s dominance was the biggest differentiator on last year’s team. The 2025 squad, which has been outscored by 23 runs despite a 20-14 record, needs him to approximate that performance.

What must change: Bullpen depth

Despite an elite offense, the Red Sox have hovered around .500 because of a thin bullpen. The relievers have blown as many saves (eight) as they’ve converted and only one team has seen a higher rate of inherited runners score. Closer Aroldis Chapman has been fine, but he hasn’t had enough situational help. Boston ranks in the middle of the pack with a 4.11 relief ERA and its 10 holds are tied for the fewest of any bullpen. The rotation has been solid, but it’ll need more support to remain that way.

What must change: The offense

Even after an eight-run outburst against the division-leading Mariners on Sunday, Texas ranks 29th in run scoring. Only the Rockies have scored fewer. It’s a stunning turnaround for an offense that kept scoreboards spinning in 2023 on the way to a World Series title. Last year’s falloff was steep, and based on what we’ve seen so far, hopes for positive regression are fading. Adolis Garcia is having another down season. Marcus Semien is below replacement. And the key additions from the winter — Joc Pederson and Jake Burger — have hurt more than they’ve helped. Pederson is hitting a remarkable .094 with a .334 OPS, and Burger (.561) was sent to the minors. Not good. The Rangers’ brass has taken note: Offensive coordinator Donnie Ecker, who was with the club during its 2023 run, was fired after Sunday’s game.

What must change: Carlos Correa

For once, we don’t have to cite the availability of the Twins’ stars as their primary problem. That’s still an issue, too, as Royce Lewis has yet to make his season debut — but the larger problem has been the star who has stayed on the field, Correa, is off to a miserable start. He’s hitting .216 with a lone homer and a .560 OPS to begin the season, hamstringing a Twins lineup that has struggled. Everything is off, even Correa’s plate discipline, as he has walked at a rate less than half his career norm. The Twins need more to turn around than just Correa, but no one else on the roster has fallen as far below expectation as he has.

What must change: Powerless stars

After the formerly punchless Royals hammered seven homers in Baltimore on Sunday, the Blue Jays sank to last in the majors with 23 homers. The power trio of Vladimir Guerrero Jr., Anthony Santander and Bo Bichette have hit nine of those dingers between them — and that’s just not enough. Guerrero will be fine. Bichette has recovered most of the batting average he lost during last year’s .225 season, but he has homered only once. This is a player in his age-27 season who topped 20 homers in each season from 2021 to 2023. Finally, Santander has flailed during his first Toronto season, hitting four homers with a 67 OPS+. This can’t continue if the Jays are to contend.

What must change: The pitching

The Brewers are built to win on pitching and defense. Every year, they overperform their projections because of an organizational ability to find, or produce, quality pitchers. But so far, they just haven’t found enough of them in 2025. The overall run prevention has been off. In the first season after Willy Adames’ departure, the team defense has been more decent than elite. The rotation has received good work from Freddy Peralta, Jose Quintana and upstart Chad Patrick, but the falloff after that has been steep. Brandon Woodruff might return to the mix soon and that will certainly help. More troubling is Milwaukee’s normally airtight relief staff, which has struggled to finish games and strand inherited runners.

This all needs to turn around — and fast. With the Cubs emerging as a potential powerhouse in the NL Central, being an above-average team is no longer the bar to clear in the division. And it’s unlikely the Central’s second-place club is going to have a chance at a wild-card slot — not in this league.

What must change: Home-field disadvantage

No matter what happened, this was going to be a strange season for the Rays. Playing in a minor league facility owned by a division rival was going to take some getting used to. The problem for the Rays is that they need to get used to it quickly, because of a schedule heavy on early home games. When the Rays depart for a six-game trip on June 8, they will have played nearly twice as many games in Tampa (43) as on the road (22). That means, of course, that the Rays will have a road-heavy schedule after that, which would be fine if the Rays were playing well at George M. Steinbrenner Field — but they aren’t. When the Rays return to Florida on Tuesday, they’ll be 9-13 at their temporary venue. With a lot more games in Tampa coming up, it’s an issue they need to fix fast. If they don’t, they’ll be looking at an uphill battle for playoff contention, and most of those hills will be confronted away from home.

What must change: Lead protection

The Reds might be good. The pitching staff (122 ERA+) ranks third in the NL. The rotation and the bullpen have contributed even though presumed closer Alexis Diaz floundered so badly that he was sent to the minors. Emilio Pagan has been OK in Diaz’s place, but he’s better suited for set-up work. Diaz’s trouble started last season, so it’s hard to say where his trajectory is headed. Recently recalled Luis Mey has electric stuff, but he’s unproven and prone to lapses of command. However it happens, manager Terry Francona needs someone to step up to lock down the ninth because the overall pitching is contention-worthy. The lineup … well, it’s another reason why the Reds can’t afford back-of-the-bullpen inconsistency.

What must change: The defense

This is shaping up as an exciting first season in Sacramento for the Athletics. The offense has been productive and looks legit, especially if rookie Nick Kurtz hits the ground running. The pitching is going to be more of a scramble, but what would help if the Athletics could field. They rank last or second to last in the leading defensive metrics. Only the Red Sox have committed more errors. Some teams can overwhelm opponents by favoring offense over defense at most positions, but the Athletics aren’t likely to be one of them. Key spots to shore up are second base and third base, positions that aren’t producing at the plate, either, so at the very least the Athletics could favor a glove.

What must change: Ryan Helsley

The Cardinals are perfectly mediocre, owning a run differential that has hovered around break even. Their record is a little worse than the expectation the so-so differential portends, largely because of a 4-5 record in one-run games — two of those coming in Sunday’s doubleheader against the Mets. This is not exclusively because of Helsley, but he has not been on his game so far with two blown saves in seven chances and walking nearly as many batters as he has struck out. The strikeout and walk rates are alarming, as they reflect what Helsley was early in his career before he ascended to All-Star status. If the mediocre Cardinals are going to do better than middling, they need their star closer to help them close out more than their share of close games. The kicker, though, is that if the Cardinals go into offload mode, this version of Helsley isn’t going to look nearly as alluring in the trade marketplace.

What must change: Right-handed hitting

No team has lost more from its preseason projection than Baltimore, so it’s very difficult to boil it down to one big thing. The problem with right-handed hitting could also be framed as a problem with hitting left-handed pitchers. The Orioles rank fifth with a .774 OPS against righties but are dead last against lefties (an anemic .502). Their righty hitters (Tyler O’Neill, Jordan Westburg, Gary Sanchez, et al.) are hitting a collective .200/.261/.319. This of course comes after the Orioles moved in the left-field fence at Camden Yards over the winter. How’s that going? Opposing righty hitters have a .972 OPS there, while their Baltimore counterparts are at .586. The visitors have outhomered Baltimore’s righty swingers 20-8 at Oriole Park.

What must change: Dylan Crews

The Nationals are competitive already and often fun to watch. Actual contention seems like a longshot, though, especially given the current state of their bullpen. Still, the more long-term questions the Nationals can answer in the affirmative, the better they will be able to set themselves up for a real push in 2026. At some point, infield prospect Brady House should join the big league fray. Until that happens, eyeballs remain on Crews, the touted second-year player whose MLB career has sputtered at the beginning. Crews looked lost early, going 5-for-47 with zero extra-base hits to start. Then came a two-week splurge with four homers and a 1.026 OPS over 13 outings. He’s 1-for-21 since. More than anything, Crews needs to get off the roller coaster and enjoy a nice, prolonged run of good, solid consistency.

What must change: Roster make-up

What do I mean by “roster make-up”? Remember the glory days of April 12, when L.A. was 9-5 and it seemed its floor-raising project from the winter was going to work? Since then, the Angels have a minus-65 run differential, 14 runs worse than any other team and, yes, that includes the Rockies. And also, Mike Trout is back on the injured list. The Angels are in the bottom five in OPS, ERA and defensive runs saved. This incidentally isn’t a tanking team. So how to change the roster makeup? Maybe just go young and lose big? The losing might happen anyway and, besides, what the Angels are doing now is not working.

What must change: Oneil Cruz‘s defense

According to baseball-reference.com, Cruz’s offense has been nine runs better than average, once you combine his hitting (.243/.377/.505 with eight homers) and baserunning (14 steals). His defensive performance in center field is minus-9 runs, erasing all of that offensive value. His bWAR (0.5) is a product of accounting — positional value and replacement value. Cruz is now minus-12 in fielding runs over the past two seasons in center. His career figure at shortstop was minus-9. Given his speed and arm strength, wherever Cruz plays, this cannot continue to happen. For all that athletic ability and offensive output, to this point he’d have produced almost as much value as a DH.

What must change: Sandy Alcantara‘s command

It’s great to have Alcantara back after Tommy John surgery. But so far, he has been a little tough to watch. It’s often said that command lags behind stuff for many surgery returnees, and that certainly seems to be the case for the 2022 NL Cy Young winner. His walk ratio (5.9 per nine innings) is more than double his career norm and his strikeout rate (15.8%) is the lowest of his career. Alcantara threw strikes nearly 69% of the time during the three years before he was injured; this season he’s at 62%. His velocity isn’t quite all the way back either, but he’s still averaging 97.4 mph with his fastball. He’s just not putting it where it needs to be.

What must change: Fan patience

To paraphrase Timothée Chalamet, now ain’t the time for your tears, Sox fans. That was last year. The White Sox are the team nearest to me — less than two miles from my keyboard — so I get a good sampling of fan feedback as I get out and about, plus plenty from the local media. This isn’t a scientifically-informed observation, but it feels as if many are missing the point. The White Sox tore the team down to the studs — last year — and this is the aftermath. The bounce-back was never going to be immediate. This year’s team stinks, sure, but it’s playing a much better brand of baseball than it did last year. There are players on the roster now who might be around for awhile and more are on the way. The rebuild isn’t even 20% complete and another 100-plus losses is a near certainty, but things are better. They had to be. Watching a team come together required patience, but it’s better than what White Sox fans dealt with a year ago.

What must change: Everything

The Rockies’ saves leader (Zach Agnos with two) has struck out one of the 26 batters he has faced. Their wins leader (Chase Dollander, a legitimately exciting prospect) has a 6.48 ERA. The team OPS+ is 62. Their leader in plate appearances (Ryan McMahon with 136) has an OPS of .574. Did the Rockies tear down? If so, how long have they been rebuilding? It’s really hard to make sense of the last half-decade or so of this franchise, and at this point, there seems to be no relief on the horizon. They did change hitting coaches.
