Gavin Williams prop prices compared with fair value
Best available price against the market's own fair value, live from our MLB board
Every strikeout prop posted on Gavin Williams for an upcoming game where at least four books quote both sides of the same number, beside the fair value those books imply once each one's margin is removed. Prop prices are captured on the morning of the game and are not refreshed afterwards.
Live prop prices for Gavin Williams load here from our MLB board. If nothing appears, no book has a two sided prop posted on him for an upcoming game, so there is no fair value to compare a price against. The full price vs fair board carries every player priced today.
Fair value is what the price would be with the sportsbook margin removed: each book's own two prices on the same number, margin taken out, then the median across every book quoting that number. A side needs at least four such books before it carries a fair value here. This is market arithmetic, not a projection of ours and not a pick. What fair value means and the full MLB price vs fair board.

Where these numbers come from
Game logs and season line. Our own game archive, updated daily from the official league feed.
Advanced metrics. Our pitch-tracking table, 2026 season through 2026-09-25; percentiles computed against all qualified starters in the same window. Blank cells mean the game postdates the window, and we leave them blank rather than estimate.
Prop lines. Our odds archive: each book's earliest recorded capture that morning, median across quoting books. Openers, never closers.
Information, not betting advice. This page reports what happened, with windows and sample sizes attached. Small samples are labeled with their n so you can weigh them accordingly. No picks, no recommendations.
