2026 review

Carson Seymour was a middle reliever whose results beat his contact quality: a 4.55 ERA and 1.48 WHIP in 31.2 IP, with a 16.4 K% and an 11.4 BB% over 140 BF across 25 games and 1 start, picking up 1 SV and 8 HLD against 3 BS. He moved between the majors and San Francisco, optioned Mar 23, recalled Jun 5, optioned Jun 11, and recalled Aug 3, throwing 4.1 IP over 2 games in Jun, 15.1 IP over 10 games in Aug, and 12.0 IP over 13 games in Sep. Drafted at NFBC ADP rank 751, a rare pick taken in just 9 of 674 drafts, he finished 920th of 1472 in the TDK LABS 5x5 value rank, 594th of 811 pitchers, and 458th of 575 relievers. His 4.55 ERA ran 1.68 below his 6.23 xERA over 140 BF. The TDK LABS card flagged him as a risky multi-inning bridge with no save path in early Jun, sent him back down mid-month after a rough relief turn, and by late Sep still had him as a middle-relief arm in a fluid pen with no leverage path.
