Matchup	Moneyline	Probability

PHI @ MIA	PHI -105 / MIA -114	PHI 49.0% / MIA 51.0%

Looking closer at the Braves and Mets matchup, Atlanta holds the higher probability for good reason. Offensively, the Braves have outpaced New York this season, accumulating 523 runs compared to the Mets’ 446. Atlanta also boasts a stronger lineup with a .249 batting average and .731 OPS, besting New York’s .235 average and .694 OPS. On the mound, the Braves’ pitching staff has been much more effective, holding a 3.744 ERA and 1.25 WHIP. Meanwhile, the Mets have struggled more consistently, posting a 4.176 ERA and 1.30 WHIP.

For the Marlins and Phillies, Miami enters with a slight statistical edge on both sides of the ball. The Marlins’ offense features a .733 OPS with 472 runs scored, narrowly edging out Philadelphia’s .706 OPS and 467 runs. Miami’s pitching staff also holds a lower team ERA (4.107) than the Phillies (4.250), validating their position as the slight favorite in the probability projections.
