Chicago Cubs

Milwaukee Brewers at Chicago Cubs

The Milwaukee Brewers take on the Chicago Cubs in a marquee matchup that could have significant implications for the NL Central race. With Milwaukee boasting an impressive 85-53 record, they sit atop the division, but the Cubs are hot on their heels at 78-60.

Our GameSim model has this game pegged as a nail-biter, predicting a score of 5.7-5.4 in favor of the Cubs, giving them a slim 51% chance of victory.

Offensively, look for Gary Sanchez of the Brewers, who is predicted to hit .307 with 0.9 RBI, to provide the fireworks. Meanwhile, Cubs’ Miguel Amaya could be a difference-maker with his .301 average and 0.8 RBI projection. With Vegas setting the over/under at 10.5, expect a high-scoring affair.
