How is Ian Seymour performing?
Ian Seymour is a strikeout-heavy starter with clear swing-and-miss stuff. A 35.68% strikeout rate and 29.65% whiff rate show consistent ability to miss bats across 16 starts. The constraint is innings: he's averaging 5.23 per start, which limits total strikeout volume and suggests either efficiency issues or workload management. The raw stuff is there, but shorter outings cap his impact per game.
