March 24, 2026
The Giants optioned Seymour to Triple-A Sacramento on Tuesday, Shayna Rubin of the San Francisco Chronicle reports.
Analysis
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.

2025 Fantasy Outlook
A big 6-foot-6 righty whose groundball rates have typically been above 50 percent thanks to a plus sinker and plus slider, Seymour may profile best as a reliever long term due to his lack of a quality third pitch. He logged a 4.82 ERA, 1.57 WHIP and 132 strikeouts in 134.1 innings across 29 appearances for Triple-A Sacramento, where he will likely return to start 2025. Seymour was added to the 40-man roster this offseason to protect him from the Rule 5 draft, and he could work as a spot starter or long reliever for the big club.
