Ian Seymour, a promising left-handed pitcher for the Tampa Bay Rays, is emerging as a solid fantasy baseball waiver wire option for Week 9 of 2025. While his recent performance at Triple-A has shown some struggles with a 5.27 ERA and 1.83 WHIP over his last three starts, his overall potential remains high, highlighted by 22 strikeouts in 13.2 innings. Prior to this skid, Seymour posted an impressive 1.73 ERA and 0.99 WHIP for the season. With the Rays' current pitching depth and the expected call-up by July, Seymour is a strategic add for teams in 14+ league formats, especially those looking for high strikeout potential.

As he awaits his MLB debut, Seymour has been successful in utilizing his flat fastball and strong changeup, marking him as one of the more underrated lefty prospects in baseball. With Zack Littell showing signs of improvement, the competition for a spot in the rotation is heating up, making it crucial for fantasy managers to act quickly. Keeping Seymore on the radar can pay dividends as the season progresses.
