The Philadelphia Phillies head south to face their perennial rivals, the Atlanta Braves, in a game that could define their season. With the Braves leading the season series, the Phillies will be eager to turn the tide and boost their postseason hopes.
Our model gives the Braves a 56% chance of victory, projecting a 5.1 to 3.9 win over Philadelphia. The key to the Braves' success has been their pitching depth, with veteran Chris Sale expected to deliver another solid performance, striking out nearly seven batters over 6.1 innings. On the other hand, Andrew Painter of the Phillies will need to overcome his 6.41 ERA if Philadelphia hopes to stay competitive. Check out the full game prediction here.
