Bet to +105 for G7 if you don’t have M’s futures If you have futures you have options: * Combined exposure = 6.7u to win from 0.6u risk (+1117 avg) - including Pennant Exacta * Simple hedge → bet Jays to win ~3u = flatten AL pennant profit. * Partial hedge → 1.5u win or ~0.75u risk at –125 = freeroll futures. * “Team No Hedge” argument — Mariners still +EV at near 50% win prob. * Key question: comfort level with a 7u swing on one game.

Just a dabble here as most projections I’m seeing have Bieber at 5 strikeouts but at plus odds I’ll take a shot at the under here. The biggest variable is this is an elimination Game 7 for the Blue Jays, meaning if he’s in trouble or not sharp they aren’t going to give him a long leash. The Blue Jays will keep him out there as long as he’s dealing, but they don’t need length here, they need sharpness. Projection sites are going to treat Bieber with a median perspective but there’s a wider range of outcomes than sites can project here given the elimination factor.
