As the MLB season hits its stride, the race for playoff spots intensifies. September 3, 2026, promises an exciting trio of games featuring teams with postseason aspirations. With the Milwaukee Brewers visiting the Chicago Cubs, the St. Louis Cardinals taking on the Los Angeles Dodgers, and the Chicago White Sox battling the Houston Astros, there’s plenty on the line for fans and players alike.

In the heart of Chicago, the Brewers and Cubs are set to clash in a game that could significantly impact their respective playoff trajectories. The Brewers, boasting a solid 87-53 record, are the favorites with a 58% win probability according to our GameSim predictions. Milwaukee's Logan Henderson is projected to deliver a strong performance on the mound with 6.6 strikeouts and an ERA of 2.95 over six innings.
Meanwhile, Kevin Gausman of the Cubs will need to improve upon his predicted 7.00 ERA if Chicago hopes to counter the Brewers' potent lineup. Offensively, keep an eye on Milwaukee’s Jackson Chourio, expected to contribute significantly with an estimated 0.3 home runs and a .299 average. The Cubs' Pete Crow-Armstrong will aim to match that output, with projections showing 0.4 home runs and a .250 batting average.
The Dodgers are looking to solidify their position as they host the Cardinals, holding a slight edge with a 59% chance of victory as per our simulation model. Los Angeles's Tarik Skubal is anticipated to be a key player, delivering 7.9 strikeouts and maintaining a tidy ERA of 3.18 over 6.5 innings.
For the Cardinals, Quinn Mathews will be tasked with limiting the Dodgers' high-octane offense, aiming for 4.8 strikeouts and an ERA of 3.98. With both teams vying for crucial wins, fans can expect a tactical showdown. The Dodgers' bullpen, with Tanner Scott and his 3.06 ERA, is poised to play a crucial role in sealing the game.
In Houston, the Astros will host the White Sox in a contest that could be pivotal for both teams' postseason chances. Our GameSim predictions give the Astros a 57% likelihood of victory, thanks in part to Hunter Brown’s projected 6.7 strikeouts over 5.6 innings.
The White Sox, with Luis Castillo on the mound, will aim to upset these odds. Castillo is expected to deliver 4.4 strikeouts with a 5.01 ERA, a performance that will need to be bolstered by strong offensive support. Houston's bullpen, led by Josh Hader, anticipated to strike out 1.3 in a single inning, might just have the edge to close out the game.
