COLUMBUS, Ohio — The Columbus Clippers didn’t just unveil a coaching staff for the 2026 season on Monday. They sent a message.
In a move that underscores how deeply the Cleveland Guardians value continuity, development, and institutional DNA, the Clippers announced a staff stacked with familiar names, recent alumni, and rising instructors from across the Guardians’ system. At the center of it all is a clear theme: trust the people who have lived it.
The headline addition is former Guardians bullpen arm Nick Wittgren, who was officially named one of Columbus’ pitching coaches for the upcoming season. Less than a year after announcing his retirement from playing, Wittgren has already climbed into a prominent developmental role — a rapid transition that speaks volumes about how highly he is regarded within the organization.
Wittgren’s resume is well-known in Cleveland. Over an MLB career that included stops with the Guardians, Marlins, Cardinals, and Royals, the right-hander carved out a reputation as a steady, no-nonsense reliever who understood the grind of a long season. Now, instead of attacking hitters, he’ll be shaping the next wave of Guardians arms.

“This is the kind of move contenders make quietly,” one Minor League evaluator said. “You put former big leaguers with credibility in front of young pitchers and let experience do the teaching.”
Wittgren will share pitching duties with Andrew Moore, who returns to Columbus after spending last season coaching at Single-A Lake County. Moore’s promotion signals internal confidence in his developmental approach, while pairing him with Wittgren creates a balance of analytical growth and lived MLB experience.
Overseeing it all once again is Andy Tracy, entering his sixth season as manager of the Clippers. Tracy’s tenure hasn’t been flashy, but it has been steady — exactly what the Guardians covet at the Triple-A level. In six seasons, Tracy has guided Columbus to a 356–360 record, highlighted by a second-half title in 2024 that reasserted the Clippers as a legitimate pipeline to Cleveland rather than just a holding pen.
Stability continues behind the scenes as well. Daniel Robertson returns for his fifth season as a coach in the Guardians system and his third as Columbus’ bench coach. Robertson has quietly become one of the organization’s most trusted communicators, often acting as the bridge between player development philosophy and daily clubhouse reality.
On the offensive side, the Clippers are doubling down on continuity. Former Ohio State standout Matt Angle is back for his second season as hitting coach, bringing with him a collegiate background and a reputation for modernized swing work. Angle will be joined by Ordomar Valdez, who spent last season as a hitting coach with Lake County and now moves up a level.
The Guardians’ development staff has long emphasized consistency in messaging from rookie ball to Triple-A, and this alignment — Angle and Valdez running parallel programs — reflects that philosophy in action.

Perhaps the most telling promotion belongs to Mac Seibert, who steps up from managing the Dominican Summer League Guardians to serve as Columbus’ development coach. That leap is significant. Seibert’s work with international prospects placed him at the very foundation of the Guardians’ talent pipeline, and his presence in Columbus suggests the organization wants its development principles reinforced at the doorstep of the majors.
The rest of the staff rounds out a group heavy on recognition and proven performance. Jake Legan, the 2025 International League Athletic Trainer of the Year, returns for his third season, assisted by Frank Sammons, who was promoted from Lake County. Strength and conditioning will be handled by Tyler Grisdale and Mo Cuevas, the latter fresh off being named the 2024 Eastern League Strength Coach of the Year.
It’s a staff built less on splash and more on substance — and that may be exactly the point.
As the Guardians continue to chase sustained success at the Major League level, the importance of Triple-A cannot be overstated. Columbus is where prospects either prove they’re ready or learn why they’re not. By filling the Clippers’ dugout with people who have worn the uniform, coached within the system, and earned trust internally, Cleveland is betting on familiarity over flash.
The Clippers will open their 2026 season on March 27 at Iowa, before returning home to host the Indianapolis Indians on March 31. When they do, they won’t just be playing for wins — they’ll be serving as the clearest reflection yet of how the Guardians see their future.
And judging by this staff, that future looks deliberately, unmistakably homegrown.
