Scout’s note
Díaz signed out of Valencia, Venezuela and has 67 strikeouts in 85.0 innings for the Tacoma Rainiers this year; he debuted in the majors on 2021-09-17. He's in our Index — tracked, not flagged. The boards bet on mispricing, and right now his account with reality is square.
Current signals
The read: Díaz 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.
