Ian Seymour Has Become A Rays Rotation Answer Nobody Saw Coming

Ian Seymour's transition to a starting role has bolstered the Tampa Bay Rays' rotation, showcasing their knack for transforming talent into top-tier pitchers.

The Tampa Bay Rays keep finding answers in places other teams might overlook, and Ian Seymour has become the latest example.

What started as a midseason experiment turned into a real rotation solution. Seymour opened his debut season in 2025 in the bullpen, stayed in that role to begin 2026, and then got moved into the starting mix in the middle of the year. His first start came on June 8 against the Boston Red Sox, and at the time it was fair to wonder whether the move was temporary or simply a bridge while the Rays dealt with injuries and inconsistency elsewhere.

Two months later, that question has been settled. Seymour has pitched his way into a permanent spot.

Even with Shane McClanahan set to return from the injured list, Freddy Peralta acquired from the New York Mets ahead of the MLB trade deadline and Griffin Jax avoiding serious injury, Seymour still needs to keep taking the ball for Tampa Bay. He has earned that by giving the Rays steady work at the back end of a rotation that also includes All-Stars Drew Rasmussen and Nick Martinez.

The numbers back up the role change. Across 16 outings, including that June 8 start against Boston, Seymour owns a 3.58 ERA and a 3.63 FIP over 65.1 innings. He has allowed 51 hits and 16 walks, but the real separator has been his swing-and-miss stuff.

Seymour has 115 strikeouts in 2026. Of those, 82 have come since that first start on June 8, meaning he had just 33 strikeouts through his first 31 innings of the season. Over his last 65.1 innings, he has posted a 30.9% strikeout rate, which ranks 10th among pitchers with at least 50 innings in that span, according to Brian Murphy of MLB.com.

That puts him just ahead of Paul Skenes, the Pittsburgh Pirates ace and reigning National League Cy Young Award winner, who is sitting at 30.5%.

For Tampa Bay, the bigger picture is simple: the rotation is a strength, and Seymour has become a major reason why. He has settled in quickly after moving back into a starting role, which is the role he held throughout his career before reaching the Big Leagues.
