Marcus Semien prop prices compared with fair value

Best available price against the market's own fair value, live from our MLB board

Every total bases and hits prop posted on Marcus Semien 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 Marcus Semien 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.
