Carson Seymour: Everything you need to know

The Giants optioned Seymour to Triple-A Sacramento on Tuesday, Shayna Rubin of the San Francisco Chronicle reports. Although he finished the Cactus League with a strong 2.92 ERA and 1.05 WHIP over 12.1 innings, Seymour will come up short in the race for a spot in San Francisco's bullpen. The 27-year-old righty may reclaim a middle-relief role with the Giants if he continues to cruise on the mound to begin the Triple-A season.

Seymour has allowed four earned runs on eight hits and three walks while striking out eight across 9.1 innings in four Cactus League outings, including one start. While he has spent most of his time in the minors as a starter, the Giants' bullpen competition is wide open, and a relief role is Seymour's best shot at making the Opening Day roster. The right-hander made his big-league debut with San Francisco in the 2025 campaign and primarily operated out of the bullpen, finishing with a 4.75 ERA, 1.39 WHIP and 26:13 K:BB across 36 innings in 16 outings (three starts).

Seymour struck out a batter and allowed one earned run on three hits over one inning of relief in Sunday's 10-2 loss to the Dodgers. Seymour had started in each of his previous three appearances, but after he turned in an 8.68 ERA and 1.71 WHIP across 9.1 innings in those outings, he was moved to the bullpen. The Giants called on Seymour to mop up in the ninth inning of Sunday's blowout loss, and most of the 26-year-old righty's appearances for the remainder of the season are likely to come in lower-leverage spots.
