The Yankees’ coaching staff will look a lot different in 2026.

That’s because longtime bullpen coach Mike Harkey and infield/first base coach Travis Chapman won’t return next season, per SNY’s Andy Martino. SNY also reported that assistant hitting coach Pat Roessler will not return in that role for non-performance reasons and that the Yankees are considering him for other jobs.

Jake Hirst, the team’s minor league hitting coordinator, will join Aaron Boone’s big league staff in a corresponding move.

Martino added that other roles on the staff are being discussed.

Pitching coach Matt Blake and major league field coordinator/director of catching Tanner Swanson have club options, so those need to be decided on. There’s also bench coach Brad Ausmus and third base/outfield coach Luis Rojas, two former managers on expiring contracts this year.

Per SNY, Rojas interviewed for the Orioles’ vacant managerial role, but the ex-Mets skipper would be welcomed back in the Bronx if he does not land such a job this offseason.

The Yankees also gave the Twins permission to talk to hitting coach James Rowson about their managerial opening.

Harkey, approaching his 59th birthday, just wrapped up his 16th season as the Yankees’ bullpen coach. He held the position from 2008-2013 before returning prior to the 2016 season.

The Yankees’ relievers didn’t pitch particularly well in 2025, as the bullpen’s 4.37 ERA ranked 23rd in baseball as injuries ravaged the group and high-leverage arms like Devin Williams and Luke Weaver struggled. The unit was actually worse after a trade deadline makeover brought in David Bednar, Camilo Doval and the quickly-demoted Jake Bird, as the pen’s 4.74 ERA from Aug. 1 through the end of the regular season ranked 26th.

Yankees relievers also allowed 18 earned runs over 26.1 innings in the postseason before the team was eliminated in the ALDS.

Prior to 2025, the Yankees’ bullpen had the third-best ERA in the majors since Harkey rejoined the organization in 2016.

Chapman, meanwhile, completed his fourth year in his role, which also included being the organization’s “Director of Infield.” It was the 47-year-old’s 13th overall season with the Yankees.

While errors are hardly the best stat for measuring defense, the Yankees had the fifth-most errors at second base, third base and shortstop this past season. Second and third were eventually sorted out with metrics darlings — Jazz Chisholm Jr. returned to second after playing third to accommodate DJ LeMahieu, while Ryan McMahon was acquired for the hot corner — but Anthony Volpe’s once Gold Glove defense regressed at short.

Volpe, who routinely worked on his defense with Chapman before games, ended the season with -7 Outs Above Average, a -5 Fielding Run Value and two Defensive Runs saved. His 19 errors were the fourth-most in the majors.

Roessler, 65, spent two seasons as an assistant hitting coach with the Yankees, while Hirst became the team’s minor league hitting coordinator last offseason after previously working as an assistant hitting coordinator and minor league hitting coach. He has already worked with several of the Yankees’ younger hitters, including Volpe, Austin Wells and Jasson Domínguez, in the minors.
