2026 review

Seranthony Domínguez was a contact-management reliever who kept hitters off the barrel, his 24.2 Hard% over 161 BBE the 16th lowest of 517 pitchers with 100+ BF. He posted a 3.63 ERA and a 1.24 WHIP in 62.0 IP across 67 games, with a 25.0 K% and an 11.9 BB% over 260 BF, going 5-3 with 12 SV, 8 HLD, and 6 BS. Signed as a free agent by CHW on Jan 29, he was traded to SEA on Aug 2. Drafted at NFBC ADP rank 293, he finished 308th of 1472 in the TDK LABS 5x5 value rank, 15 spots below, and 65th of 575 relievers. He posted a 0.00 ERA in 11.1 IP in Sep after a 5.40 ERA in 13.1 IP in Aug. The TDK LABS card shifted its read on him over the year: in early May it had him as the clear closer in CHW with nobody pushing him for the role, and by late Jul it described a fluid committee there instead. After the trade, mid-Aug had him working as leverage relief, and by late Sep the card had him drifting toward a middle-relief role following a blown save.
