EARLY IN THE 2023 season, Aaron Leanhardt started asking New York Yankees hitters what they needed to perform better. He was a minor league hitting coordinator for the team, and with league-wide batting average the previous year at its lowest point in more than a half-century, Leanhardt approached that spring with a specific question: How, in an era ruled by pitching, could offense keep up?
“Players were frustrated by the fact that pitching had gotten so good,” Leanhardt said.
An MIT-educated physics professor at the University of Michigan for seven years, Leanhardt left academia for athletics specifically to solve these sorts of problems. And as he spoke with more players, the framework of a solution began to reveal itself. With strikeouts at an all-time high, hitters wanted to counter that by making more contact. And the easiest way to do so, Leanhardt surmised, was to increase the size of the barrel on their bat.
Elongating the barrel — the fat part of the bat that generates the hardest and most contact — sounded great in theory. Doing so in practice, though, would increase the weight of the bat and slow down swing speed, negating the gains a larger sweet spot would provide.
Leanhardt started to consider the problem in a different way. Imagine, he told players, every bat has a wood budget — a specific amount of weight (usually 31 or 32 ounces) to be distributed over a specific length. How could they invest a disproportionate amount of that budget on the barrel without throwing off the remainder of the implement?
The answer led to what could be the most consequential development in bat technology since a generation ago when players forsook ash bats for maple. The creation of the bowling pin bat (also known as the torpedo bat) optimizes the most important tool in baseball by redistributing weight from the end of the bat toward the area 6 to 7 inches below its tip, where major league players typically strike the ball. Doing so takes an apparatus that for generations has looked the same and gives it a fun-house-mirror makeover, with the fat part of the bat more toward the handle and the end tapering toward a smaller diameter, like a bowling pin.
The bat had its big debut over the weekend, as the Yankees tied a major league record with 15 home runs over their first three games. Nine of those came from five Yankees who adopted the bowling pin style: Jazz Chisholm Jr. (three), Anthony Volpe (two), Austin Wells (two), Cody Bellinger (one) and Paul Goldschmidt (one). The hullaballoo over the bats started almost immediately after Yankees announcer Michael Kay noted their shape on the broadcast, and by the end of the weekend players around the league were inquiring to bat manufacturers about getting their hands on one.
The Yankees’ barrage of long balls permeated beyond players’ fascination and into the zeitgeist. Some fans and even opposing players wailed fruitlessly about the legality of the bats — Brewers reliever Trevor Megill called the bats “like something used in slow-pitch softball” after watching his teammates surrender home run after home run over the weekend. But the bats abide by Major League Baseball’s collectively bargained bat specifications for shape (round and smooth), barrel size (no larger than 2.61 inches in diameter) and length (a maximum of 42 inches). Most also didn’t realize that the bowling pin bat was used for some of the most consequential hits of 2024 thanks to one of its earliest adaptors.
Yankees slugger Giancarlo Stanton is owed as much credit as any player for the bowling pin revolution. Leanhardt’s logic behind the bat’s geometry made sense to Stanton, whose average bat velocity of 81.2 mph last year was nearly 3 mph ahead of the second-fastest swinger and more than 9 mph quicker than the average MLB swing. Even with outlier metrics, Stanton gladly embraced a bat that could make his dangerous swing even better — and used it while pummeling seven home runs in 14 postseason games.
TO UNDERSTAND HOW the bowling pin bat works is a lesson in physics. Take a sledgehammer and a broom handle. The sledgehammer will be more difficult to swing because much of its weight is distributed to the tip. The broom handle, meanwhile, can be swung with immense speed but doesn’t contain significant mass. If the length and weight of bats are constants, the distribution of mass is the variable — and Leanhardt conceived of a bat that optimizes both so it can do the most damage.
“This bat is just trying to say: What if we put the mass where the ball is going to hit so that we have an optimized equation of mass and velocity?” said Scott Drake, the president of PFS-TECO, a Wisconsin-based wood products laboratory that inspects all MLB bats to ensure they’re within the regulations. “You’re trying to take a sweet spot and put more mass with that.
“Wood is highly variable,” he added, “and everything is a trade-off.”
In the case of the bowling pin bat, it’s a trade-off hitters using it are willing to make. Because so much of the mass is in the barrel, swings that don’t connect on it produce results often more feeble than those of traditionally tapered models. As Leanhardt said, though, if a ball off the end of a bowling pin shape leaves the bat with an exit velocity of 70 mph compared to 71 mph for the traditional one, both are likely to result in outs. The difference between a 101 mph batted ball and 102 can be a flyout versus a home run.
“That’s the question of the whole wood budget,” said Leanhardt, who left the Yankees after serving as a major league analyst during the 2024 season and currently is the major league field coordinator for the Miami Marlins. “Every penny counts. The fact of the matter is you want your barrels to count the most. You want the most bang for your buck there.”
Turning those principles into reality took buy-in from the entire bat supply chain. Once players bought into Leanhardt’s seedling of an idea, they requested samples from bat manufacturers. Leanhardt worked with a number of MLB’s 41 approved bat makers to make the idea real, and the spec bats were given model numbers that start with BP for bowling pin, though he admits that “torpedo sounds kind of cooler.”
Figuring out the right balance took time. Bowling pin bats take precision to produce. Every fraction of an ounce in bat manufacturing matters. Bats are measured not only on a standard scale but via pendulum-swing tests. The more balanced a bat, the more it oscillates. Traditional bats, their weight distributed disproportionately toward the end, didn’t go back and forth nearly as much.
With relatively lenient regulations from the league allowing manufacturers leeway to create products as long as they stay within the regulations, the new — and perhaps better — mousetrap was born. Stanton’s success was the ultimate proof of concept, and manufacturers came to spring training this year with bowling pin models for players to try in games.
“There’s new pitches getting invented every year,” said Minnesota Twins catcher Ryan Jeffers, who used a bowling pin model in the first three games this year and went 1-for-8. “We’re just swinging the same broomstick we’ve swung for the last 100 years.”
Well, similar at least. Playing in an era when the average fastball velocity was an estimated 10 mph slower than the current average of around 95 mph, Babe Ruth swung a 36-inch, 44-ounce bat. As pitch velocity increased in the decades since, players shaved ounces off bats — tools to ensure they had the requisite speed to catch up with pitches.
“The bat is such a unique tool,” Jeffers said. “You look at the history of the game, and they used to swing telephone poles. Now you try to optimize it, and it feels like some branches are starting to fall for us on the hitting side of things.”
Jeffers, who has spent countless time searching for ways to counterbalance the technological revolution that helped create a generation of pitchers with the best stuff ever seen, swung a bowling pin model from manufacturer B45 in batting practice one day this spring and proceeded to order a batch that arrived during the final two weeks of spring training. Around the same time, Chisholm received his new bowling pin bats and was struck by how he couldn’t tell the difference from his traditional model.
“I mean, it still felt like my bat,” Chisholm told reporters Sunday, echoing Jeffers’ sentiment that bowling pin varieties swing similarly to their standard counterparts. “I hit the ball at the barrel, feel comfortable in the box. I don’t know what else to tell you. I don’t know the science of it, I’m just playing baseball.”
The science is multifold. Beyond the potential increases in exit velocity from the increased mass in the barrel, the weight distribution toward the knob should promote faster swings. Among the five Yankees who have used the bat, all have seen bat-velocity increases year over year, with Volpe up more than 3 mph, Bellinger up 2.5, Wells 2, Chisholm 1.1 and Goldschmidt — an inveterate tinkerer who has also used bats with hockey-puck-shaped knobs — 0.3 mph.
“Credit to any of the players who were willing to listen to me, because it’s crazy,” Leanhardt said. “Listening to me describe it is sometimes even crazier. It’s a long-running project, and I’m happy for the guys that bought into it.”
Because the data — on bat velocity as well as effectiveness — is of such a limited sample, nobody is yet proclaiming that the bowling pin bat will unquestionably revolutionize the game. But more bowling pins will be showing up in major league games soon. Leanhardt said his new team, the Marlins, will feature players using the bat in games. Tampa Bay Rays third baseman Junior Caminero laced an RBI single Sunday with a bowling pin model. In addition to the Yankees and Marlins, the Chicago Cubs and Baltimore Orioles are seen throughout the industry as the teams that have invested the most time and money researching bat geometry and optimization.
One player who does not plan on using the bowling pin model said multiple teammates plan to at least try one in batting practice after the Yankees’ nine-homer outburst Saturday. How many eventually adopt it as their full-time piece depends on feel as much as success. Comfort with a bat is vital for it to go from BP to a big league game, and in a sport where advantages don’t stay secret very long, New York’s might wind up lasting all of one weekend.
“There’s going to be a lot more teams wanting to swing them,” Jeffers said, “because of what the Yankees did this weekend.”
The final day of the regular season is exactly two weeks away, but the race for the final Eastern Conference wild-card spot remains open for five contenders.
As play begins Thursday, the Canadiens hold the second wild card with 79 points and 25 regulation wins through 74 games; the New York Rangers are tied in standings points (and ahead in RW, with 32), but have played more games. The Blue Jackets are two behind in points, and one behind in regulation wins. The idle Detroit Red Wings (75 points, 26 RW) and New York Islanders (74 points, 25 RW) round out the quintet.
The Stathletes projection model likes the Canadiens’ chances to make the playoffs the most, at 51.7%, followed by the Blue Jackets (25.5%), Rangers (19.0%), Islanders (3.1%) and Red Wings (2.3%). How will this all shake out? Thursday’s pair of games featuring these teams will provide our next set of clues.
With the regular season ending April 17, we’ll help you track it all with the NHL playoff watch. As we traverse the final stretch, we’ll provide details on all the playoff races, along with the teams jockeying for position in the 2025 NHL draft lottery.
Points: 70 Regulation wins: 26 Playoff position: N/A Games left: 6 Points pace: 75.5 Next game: @ SJ (Saturday) Playoff chances: 0% Tragic number: E
Points: 50 Regulation wins: 14 Playoff position: N/A Games left: 8 Points pace: 55.4 Next game: vs. EDM (Thursday) Playoff chances: 0% Tragic number: E
Note: An “x” means that the team has clinched a playoff berth. An “e” means that the team has been eliminated from playoff contention.
Race for the No. 1 pick
The NHL uses a draft lottery to determine the order of the first round, so the team that finishes in last place is not guaranteed the No. 1 selection. As of 2021, a team can move up a maximum of 10 spots if it wins the lottery, so only 11 teams are eligible for the No. 1 pick. Full details on the process are here. Matthew Schaefer, a defenseman for the OHL’s Erie Otters, is No. 1 on the draft board.
In his first start since agreeing to a $170 million, six-year contract, the left-hander pitched a career-best eight innings as the Red Sox shut out the Baltimore Orioles 3-0 on Wednesday night. Crochet also threw 102 pitches, one shy of his career high.
“My first start in college I went eight, and I haven’t sniffed it since,” Crochet said.
Crochet (1-0) gave up four hits and a walk while striking out eight in his first victory since the offseason trade that sent him from the Chicago White Sox to Boston.
“That’s the reason he’s here,” manager Alex Cora said after the game. “That’s the reason we committed to him.”
Crochet went 6-12 with a 3.58 ERA last season, a bright spot on a Chicago team that lost 121 games. He threw 146 innings, which was double his previous career total since his debut in 2020.
Then Crochet was dealt to the Red Sox, and they made their long-term commitment to the 25-year-old earlier this week.
“Going back to when the trade went through, we knew Boston was a place where we would love to be long term,” Crochet said. “Credit to the front office for staying diligent, and my agency as well.”
Now the question is less about where he’ll pitch and more about how well. He’s off to a nice start in that regard.
“I can’t think of the last time I played baseball for pride. In college, you’re playing to get drafted, and once you’re in the big leagues, you’re playing to stay in the big leagues,” Crochet said. “So to have this security and feel like I’m playing to truly just win ballgames, it takes a lot of the riff-raff out of it.”
The news all around was good for Boston on Wednesday.
It reached a $60 million, eight-year deal with young infielder Kristian Campbell, and he went out and doubled twice against the Orioles.
And Rafael Devers ended a 21-at-bat hitless streak to start the season with an RBI double in the fifth inning. He finished with two hits and no strikeouts.

LOS ANGELES — Aside from his ability to pitch and hit and stretch the boundaries of imagination, Shohei Ohtani has displayed another singular trait in his time in the major leagues: an ability to meet the moment. Or, perhaps, for the moment to meet him.
And so on Wednesday night, with his Los Angeles Dodgers looking to stay unbeaten, the score tied in the bottom of the ninth, and more than 50,000 fans standing and clenching the Ohtani bobbleheads they lined up hours in advance for, Ohtani approached the batter’s box — and his teammates expected greatness.
“He’s going to end this right here,” Dodgers third baseman Max Muncy said he thought to himself.
“We knew,” starting pitcher Blake Snell said. “It’s just what he does.”
Validation came instantly. Ohtani stayed back on a first-pitch changeup from Raisel Iglesias near the outside corner and shot it toward straightaway center field, 399 feet away, for a walk-off home run, sending the Dodgers to a 6-5, come-from-behind victory over the reeling Atlanta Braves.
“I don’t think anybody didn’t expect him to hit a walk-off home run there,” Dodgers utility man Tommy Edman said. “It’s just a question of where he’d hit it.”
The Dodgers are now 8-0, topping the 1933 New York Yankees of Lou Gehrig and Babe Ruth for the longest winning streak to begin a season for a reigning champion. The Braves, meanwhile, are 0-7, the type of record no team has ever recovered from to make the playoffs. And Ohtani, with three home runs and a 1.126 OPS this season, just keeps meeting moments.
“He’s pretty good, huh?” Dodgers outfielder Teoscar Hernandez said. “It’s Shohei. He’s going to do that. He’s going to do things better than that.”
On Aug. 23 last year, Ohtani reached the 40/40 club with a walk-off grand slam. Five days later, the Dodgers staged a second giveaway of his bobblehead — one that saw his now-famous dog, Decoy, handle the ceremonial first pitch — and Ohtani led off with a home run. On Sept. 19, Ohtani clinched his first postseason berth and ascended into the unprecedented 50/50 club with one of the greatest single-game performances in baseball history — six hits, three homers, two steals and 10 RBIs. Barely two weeks later, he homered in his first playoff game.
When Ohtani came up on Wednesday, he had what he described as a simple approach.
“I was looking for a really good pitch to hit,” Ohtani said through an interpreter. “If I didn’t get a good pitch to hit, I was willing to walk.”
Of course, though, he got a good pitch.
And, of course, he sent it out.
“You just feel that he’s going to do something special,” Dodgers manager Dave Roberts said. “And I just like the way he’s not pressing. He’s in the strike zone, and when he does that, there’s just no one better.”
The Dodgers began their much-anticipated season with a couple of breezy wins over the Chicago Cubs from Japan, even though Mookie Betts and Freddie Freeman did not play in them. They returned home, brought iconic rapper Ice Cube out to present the World Series trophy on one afternoon, received their rings on another and swept a three-game series against the Detroit Tigers. Then came the Braves, and the Dodgers swept them, too — even though Freeman, nursing an ankle injury caused from slipping in the shower, didn’t participate.
The Dodgers already have two walk-offs and six comeback wins this season.
Wednesday’s effort left Roberts “a little dumbfounded.”
A nightmarish start defensively, highlighted by two errant throws from Muncy, spoiled Snell’s start and put them behind 5-0 after the first inning and a half. But the Dodgers kept inching closer. They trailed by just two in the eighth and put runners on second and third with two out. Muncy came to bat with his batting average at just .083. He had used the ballyhooed “Torpedo” bat for his first three plate appearances, didn’t like how it altered his swing plane, grabbed his usual bat for a showdown against Iglesias and laced a game-tying double into the right-center-field gap.
An inning later, Ohtani ended it.
“Overall, not just tonight, there is a really good vibe within the team,” Ohtani said after recording his fourth career walk-off hit. “I just think that’s allowing us to come back in these games to win.”
The Dodgers’ 8-0 start has allowed them to stay just ahead of the 7-0 San Diego Padres and the 5-1 San Francisco Giants in the National League West. Tack on the Arizona Diamondbacks (4-2) and the Colorado Rockies (1-4), and this marks the first time in the divisional era that an entire division has combined for at least 25 wins and no more than seven losses, according to ESPN Research. The Dodgers’ and Padres’ starts mark just the fifth season in major league history with multiple teams starting 7-0 or better, and the first time since 2003.
The Dodgers famously overcame a 2-1 series deficit to vanquish the Padres in the NL Division Series last year, then rode that fight to their first full-season championship since 1988.
That fight hasn’t let up.
“It feels like this clubhouse is carrying a little bit of the attitude we had last year that we’re never out of a game and we’re resilient, and we’ve been carrying it into this season,” Muncy said. “It’s been fun to watch. The guys don’t give up. Bad things have happened, and no one’s really been down or out on themselves. Everyone’s just, ‘All right, here we go, next inning, let’s get after it.’ The whole team, top to bottom, has been doing that. It’s been making it really, really fun to play.”
