Ian Seymour - Fantasy Baseball Prospects Waiver Wire Stashes (Week 10)

Fantasy Baseball Prospects, Waiver Wire Stashes, MLB Rookies Call-Ups Sleepers

Ian Seymour is a fantasy baseball waiver wire stash for Week 10 (2025). Target Ian Seymour as a top prospect free-agent waiver wire pickup for fantasy baseball.

BALLER MOVE: Add in 14-team leagues

CALL-UP ETA: July

ANALYSIS: While the Rays do not have a clear opening for pitching prospect Ian Seymour at the moment, he is worth stashing in deeper leagues, given his elite strikeout upside. Through 55 innings at Triple-A this season, the left-hander has struck out an impressive 78 batters across 55 innings. Across this stint, he has held a 3.11 ERA with a 1.22 WHIP.

Seymour has tallied at least eight punchouts in seven of his 11 outings. He has hit the double-digit mark in two, including his most recent start against Triple-A Memphis.

During his first taste of Triple-A last summer, Seymour tallied just 63 punchouts (in a near-dientical 54 innings). However, he was slightly more effective, holding a 2.33 ERA with a 1.15 WHIP.

Currently, Zack Littell holds the No. 5 spot in the Tampa Bay rotation and was one of the most consistent pitchers in May, holding a 2.88 ERA with a 0.98 WHIP. As a result, Seymour will have to wait for an injury. However, if a Rays pitcher were to go down, Seymour would be viewed as a priority target in all standard leagues.
