SCOTTSDALE, Ariz. — Justin Verlander struck out one and allowed a solo home run while pitching two innings in his spring training debut for the San Francisco Giants on Monday.

Verlander’s first start of the spring came four days after the three-time Cy Young Award winner’s 42nd birthday.

After allowing the two-out homer to Colorado’s Michael Toglia in the first inning, Verlander walked the next batter before retiring the last four he faced. All three Rockies hitters in the second were retired on fly balls.

Verlander’s 262 career wins are the most among active pitchers. The right-hander is preparing for his 20th big league season and his first with San Francisco after an injury-plagued 2024 in Houston. He signed a $15 million, one-year contract with the Giants.

Shoulder inflammation and neck discomfort limited Verlander to 17 starts last season, when he went 5-6 with a 5.48 ERA — a single-season worst that was more than two runs higher than his 3.30 career ERA.

LAKELAND, Fla. — Free agent reliever Andrew Chafin signed a minor league deal Monday to go to spring training with the Detroit Tigers, the team that traded the left-hander to Texas last summer.

Chafin has pitched in 105 games for the Tigers over two stints — 64 games in 2022 and 41 last year before being dealt to Texas for two minor leaguers in July. It was the fourth time in five seasons he was part of a deadline trade.

Texas in November declined a $6.5 million team option for Chafin, who instead got a $500,000 buyout. He had a 4.19 ERA while pitching 19⅓ innings in 21 appearances for the Rangers, after a 3.16 ERA with 50 strikeouts over 37 innings for the Tigers.

The 34-year-old Chafin has a 3.75 ERA in 601 big league appearances over 11 seasons for six teams. The only team he has pitched more for than Detroit is Arizona, the club that picked him 43rd overall in the 2011 amateur draft. He made 377 relief appearances and started three games for the Diamondbacks over parts of eight seasons.

Chafin made his debut with the Diamondbacks in 2014, and they traded him to the Chicago Cubs in 2020. He returned to Arizona as a free agent in 2023 and was traded that summer to Milwaukee. He also pitched for Oakland during part of the 2021 season.

Yankees slugger Giancarlo Stanton has returned to New York to undergo medical testing, multiple outlets reported Monday.

Stanton, 35, has yet to take part in spring training activities in Tampa, Fla., as he continues to battle tendinitis in both elbows. The New York Post said Monday that it was unclear whether the medical testing was for an evaluation of his elbows.

On Sunday, manager Aaron Boone told reporters that Stanton was undergoing treatment and “nothing imminent” was on tap for the designated hitter, baseball-wise.

The Yankees haven’t been pushing Stanton this spring, giving him time to rest and, hopefully, recover.

The MVP of the 2024 American League Championship Series, Stanton was bothered by deep soreness in his elbows for much of last season. He hit 27 home runs and drove in 72 runs over 114 games in the regular season.

Stanton had seven homers and 16 RBIs in 55 postseason at-bats as the Yankees reached the World Series before losing to the Los Angeles Dodgers in five games. Stanton went deep twice in the Fall Classic to follow up his four-homer showing against the Cleveland Guardians in the ALCS.

Stanton is entering his 16th major league season — the first eight coming with the Miami Marlins before he was traded to the Yankees prior to the 2018 season. He has 429 homers and 1,103 RBIs along with a .257 average in 1,649 career games.

Stanton is a five-time All-Star and he was the National League MVP in 2017 when he established career highs of 59 homers and 132 RBIs for Miami.

He has three seasons remaining on a 13-year, $325 million deal he signed with the Marlins. The Yankees hold a club option for 2028.
