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.
