How is Ian Seymour performing?
Ian Seymour is a strikeout pitcher with clear swing-and-miss stuff but limited depth so far. A 36.1% strikeout rate and 29.4% whiff rate show he's missing bats consistently across five starts. The constraint is innings per outing: he's averaging 4.9 innings per start, which caps total strikeout volume and raises questions about whether workload management or efficiency issues are limiting his time on the mound. The raw stuff is there; durability remains the question.
