Toronto Blue Jays vs. Boston Red Sox: A Tale of Two Streaks (and a Few Runs)
June 28, 2025 | Fenway Park | 7:10 PM ET

The Setup:
The Toronto Blue Jays (43-37) roll into Boston with the swagger of a team third in the AL East, while the Boston Red Sox (40-42) are nursing a five-game losing streak that’s starting to feel like a six-game losing habit. It’s a classic David vs. Goliath matchup… except David (the Jays) is 6’6” and hits 450-foot bombs.

Key Stats & Witty Observations:
- Vladimir Guerrero Jr. (.281, 11 HRs): The human highlight reel. If he doesn’t hit a home run, Fenway’s Green Monster probably feels lonely.
- Jose Berrios (3-3, 3.51 ERA) vs. Brayan Bello (3-2, 3.31 ERA): Two pitchers with ERAs that could pass for twins at a family reunion. Both are solid, but Berrios’ experience (and the Jays’ lineup) might give Toronto an edge.
- ERA Rankings: Toronto’s 4.15 ERA (20th) vs. Boston’s 3.98 (17th). The Jays’ pitching isn’t elite, but it’s good enough to let their offense do the heavy lifting.

The Odds Breakdown:
- Moneyline: Toronto (-111) is the favorite, Boston (+111) is the underdog.
- Implied Probabilities: Jays at ~52.4%, Red Sox at ~47.6%.
- Underdog Win Rate in MLB: 41%. The Red Sox are being priced higher than their historical underdog success rate. That’s like betting on a team to win the lottery while they’re still buying tickets.

Calculating the EV (Expected Value):
- Toronto’s EV: (0.524 * 0.79) - (0.476 * 1) ≈ -0.0003 (Neutral).
- Boston’s EV: (0.41 * 1.11) - (0.59 * 1) ≈ -0.13 (Negative).

The Split the Difference Strategy:
The Red Sox’ implied win probability (47.6%) is 6.6% higher than their historical underdog win rate (41%). That’s a red flag for bettors. Meanwhile, the Jays’ implied probability (~52.4%) is closer to their actual expected win rate (considering their 43-37 record and recent momentum).

Best Bet: Toronto Blue Jays (-111)
Why?
1. Momentum: The Jays are 18-13 when favored, while Boston is 14-... well, not great as an underdog.
2. Pitching Matchup: Berrios vs. Bello is a toss-up, but Toronto’s lineup (led by Guerrero Jr.) is more dangerous.
3. EV Edge: While the EV is nearly neutral, the Red Sox’ overpricing makes Toronto the safer play.

Bonus Pick: Under 9 Runs (-110)
The combined ERAs (4.15 + 3.98 = 8.13) suggest a low-scoring game. With both starters locked in and Fenway’s pitcher-friendly dimensions, the Under 9 runs is a sneaky value.

Final Verdict:
The Red Sox are a team in search of a win, and the Jays are a team in search of a longer winning streak. Bet on Toronto to end Boston’s skid… by winning.
