Top MLB Games and Probabilities on Tuesday
| Matchup | Probability (Vig-Free) |
|---|---|
| NYY @ BOS | NYY 50.3% / BOS 49.7% |
| MIL @ DET | MIL 48.8% / DET 51.2% |
| PHI @ CHC | PHI 47.8% / CHC 52.2% |
| LAD @ SF | LAD 62.4% / SF 37.6% |
If you want to back today’s heaviest favorite, placing a $20 trade on the Los Angeles Dodgers (62.4% probability) would yield a tidy profit of $10.75. On the flip side, there is nothing better than hitting big on an upset. Trading that same $20 on the heaviest underdog, the San Francisco Giants (37.6% probability), would net a sweet $31.00 profit if they pull off the win.
Matchup Spotlight: LAD @ SF
The Dodgers (16-6) stand out as today’s premier play against the Giants (9-13). Los Angeles brings an absolute juggernaut offense into Oracle Park, boasting a .293 batting average, a .366 OBP, an .873 OPS, and 133 total runs. Meanwhile, San Francisco’s lineup has been reeling, managing just a .293 OBP, a .658 OPS, and 75 runs overall.
The pitching gap is just as wide. With Yoshinobu Yamamoto taking the mound for a Dodgers staff holding a collective 3.41 ERA and a sharp 1.118 WHIP, they safely outpace Landen Roupp and the Giants’ 4.15 ERA and 1.323 WHIP. The underlying metrics heavily favor the visiting Dodgers extending their early-season dominance, making them a very real chance for a solid return.
Matchup Spotlight: PHI @ CHC
Another spot catching my eye is the Chicago Cubs (13-9) hosting the Philadelphia Phillies (8-14) at Wrigley Field. The Cubs are ascending, backed by left-hander Shota Imanaga (1-1, 2.45 ERA), who just dominated this same Phillies lineup by tying a career-high 11 strikeouts in his last outing. On the other side, Philadelphia’s Jesús Luzardo (7.94 ERA) is struggling mightily to keep runners off base. Backing the Cubs here feels like a high-value, strategic move for your portfolio.
