Carson Seymour

Scout’s note

Seymour, a 2021 sixth-round pick out of Poway, CA, has 60 strikeouts in 67.1 innings for the Sacramento River Cats this year; he debuted in the majors on 2025-06-29. An Index name: one of the game's biggest seasons, watched nightly. No call, because the engine found nothing mispriced to call.

Current signals

The read: Seymour is in the Index ungraded, on purpose: our pitching signals are stability-tested but not outcome-validated, so no big-league arm gets a board flag or a call — not even one of the best seasons in the sport. The page is here because the player matters; the grade waits for the science.
