Ian Seymour

26-Year-Old PitcherRP
Tampa Bay Rays
2025 Fantasy Outlook
An older lefty who turned 26 this offseason and had Tommy John surgery in 2022, Seymour dominated Double-A and Triple-A hitters in 2024 to the tune of a 2.48 ERA, 0.95 WHIP and 162:41 K:BB in 145.1 innings. He actually made two starts at Triple-A late in 2021 just to keep pitching after the High-A season wrapped up. Seymour's fastball velocity isn't great (sits in the low-90s), but it's got good movement, and he's incredibly crafty. He's got a plus changeup and a quality cutter, and that might be enough to get by against big-league hitters if he can throw strikes and pitch with confidence. The Rays have a plethora of rotation options, but Seymour is on the 40-man roster and should be heard from at some point this season. Given his poor fastball velocity and relatively shallow repertoire, he'll have a small margin for error as a starter, and the Rays could opt to have him work as a bulk reliever initially.

PTampa Bay Rays
August 31, 2025
Seymour (3-0) allowed four runs (one earned) on four hits and a walk over five innings Sunday, striking out eight and earning a win over Washington.
Analysis
Seymour gave up one run through three innings before two fourth-inning errors put three unearned runs on his line. The Rays scored three runs in the first three frames to lead Seymour to his second straight win. The rookie southpaw threw 57 of 82 pitches for strikes, and he generated 16 whiffs, including eight with his changeup. Seymour has looked impressive since joining the rotation, going 2-0 with a 16:2 K:BB over 10 innings. He owns a 2.97 ERA with a 42:10 K:BB at the MLB level this year. Seymour is projected to face the Guardians at home next weekend.
