The Dodgers are riding high with a 55% win probability according to our GameSim predictions, which forecast a 7.4 to 6.3 victory for the visitors.

Los Angeles will rely on the consistent hitting of Alex Freeland, who is projected to hit .303 and potentially drive in a run. Meanwhile, the White Sox will counter with Miguel Vargas, poised to be a key offensive weapon with a projected average of .350 and a likelihood of contributing both a home run and an RBI.

Milwaukee's Jacob Misiorowski is expected to be a standout performer, with a predicted 2.29 ERA over 6.6 innings, making him a formidable challenge for the Phillies’ lineup. In contrast, Philadelphia’s Andrew Painter will need to navigate the Brewers’ offense with his 4.80 ERA. Christian Yelich, hitting .298, could be pivotal for the Brewers, aiming to add to his season's home run tally.
Finally, the Seattle Mariners (36-34) are slight favorites against the Washington Nationals (35-34). With a 53% chance of victory, our GameSim model predicts a close 5.1 to 4.5 result for Seattle.
