MLB Prediction Market Odds for Yankees vs. Phillies and Blue Jays vs. Red Sox

Here are the market prices for tonight's two Apple TV+ games. Trade on these exact odds at prediction markets after claiming a welcome bonus from one of the best MLB prediction market apps.

Yankees vs. Phillies (6:40 p.m. ET, Citizens Bank Park)

  • Phillies Win: 54% Chance YES (54¢) | NO (46¢)
  • Yankees Win: 46% Chance YES (46¢) | NO (54¢)
  • Over 8.5 Runs: 49% (49¢) | Under 8.5 Runs: 51% (51¢)

Blue Jays vs. Red Sox (7:10 p.m. ET, Fenway Park)

  • Red Sox Win: 57% Chance YES (57¢) | NO (43¢)

  • Over 9 Runs: 51% (51¢) | Under 9 Runs: 49% (49¢)

MLB Predictions for Yankees vs. Phillies and Blue Jays vs. Red Sox

The most confident pick across tonight's Apple TV+ doubleheader is Red Sox to win at Fenway Park (57¢). Boston plays host in a division series opener with a lineup that has generated consistent run support at home throughout the second half of the season. The Fenway environment — the Green Monster, compact foul territory, elevated run-scoring dimensions — gives the Red Sox a structural advantage in close AL East games, and the market's 57% implied probability reflects that edge. Toronto's road numbers have been a challenge all season, and until starters are confirmed, the home-field lean is the cleanest available position.

For the early game, the Phillies to win at home (54¢) is the complementary lean. Citizens Bank Park has been one of the more hostile environments for visiting pitching staffs in the NL all season, and a Yankees club that has shown inconsistency on the road makes the Phillies a reasonable home favorite. Pair both moneylines with the Under 8.5 runs in the Yankees vs. Phillies game (51¢) — unconfirmed starters in a game that could feature quality arms from both sides makes the low-total lean defensible until the rotation picture clears.

Trade these picks by registering with any of the Action Network-verified MLB prediction market apps above before the 6:40 p.m. ET first pitch tonight.
