SF Giants Eye Young Pitchers for Key Bullpen Roles in 2026

As the SF Giants solidify their starting rotation for 2026, the team faces strategic decisions about leveraging young pitchers' immediate impact by potentially converting them into key bullpen assets.

As the SF Giants gear up for the 2026 season, their starting rotation looks solid, but there's a promising group of young pitchers ready to step up if needed. While depth is crucial, these emerging talents might find a quicker path to impact by transitioning to the bullpen. Let’s dive into five young pitchers who could potentially shine as relievers.

Carson Seymour

Seymour made his mark last season, showcasing his skills both as a starter and reliever. His high-velocity fastball and sharp slider are tailor-made for bullpen success.

After an eye-catching live batting practice session where he struck out Luis Arraez, Seymour's raw talent seems primed for a relief role. With the bullpen wide open this spring, don’t be surprised if he carves out a spot.

Carson Whisenhunt

Whisenhunt also debuted last season but faced some ups and downs. This year, he's addressed a pitch-tipping issue and is bringing more heat with his fastball. If he’s dialed in his changeup, he could be a formidable force out of the bullpen, giving opponents plenty to worry about.

Hayden Birdsong

Birdsong might just be the most crucial young arm for the Giants this season. He impressed in spring training last year, earning a bullpen spot and dominating as a reliever.

However, after a move to the rotation, his command faltered. If he regains his form this spring, a bullpen return could be the perfect fit.

Trevor McDonald

Last season, McDonald’s promotion took longer than expected, despite being one of the most promising pitchers. His style mirrors Landen Roupp, who transitioned from the bullpen to the rotation. McDonald might follow a similar trajectory, starting in relief before making a bigger impact.

Keaton Winn

Though Winn might not be top of mind, his high-velocity fastball and wicked splitter make him a solid reliever candidate. Given his injury history, a consistent relief role, even in the minors, might be the best path forward.

While not all of these pitchers will transition to relievers immediately, keeping a few stretched out for potential rotation needs is wise. However, starting the season with the top performer in the bullpen could be a strategic move, offering the Giants flexibility and strength in their pitching staff.
