Cubs at Brewers Pitching Matchup: Peterson vs. Misiorowski
David Peterson draws the start for the Cubs in this one. Peterson is a left-handed starter who has shown the ability to generate soft contact and work deep into games when his command is sharp. His effectiveness on the road against a Brewers lineup that plays well at American Family Field will be the central storyline on the mound for Chicago.
Jacob Misiorowski gets the call for Milwaukee. The right-hander is a power arm who can run his fastball up in the zone and miss bats when he is at his best. For Cubs hitters, the key will be working counts early and not letting Misiorowski settle into a rhythm. If he finds his footing, he has the stuff to make a Chicago lineup work for every run it scores.
Keys to Watch for the Cubs
- Plate discipline against Misiorowski: Misiorowski lives and dies by his ability to overpower hitters. Cubs batters who grind out at-bats and force him into the zone will give Peterson a chance to win a lower-scoring game.
- Peterson's command: Peterson needs to locate his secondary pitches consistently. If he falls behind in counts against Milwaukee's lineup, the Brewers will make him pay. His ability to work efficiently through the middle innings will determine how much the bullpen is needed.
- Situational hitting: September baseball in a divisional race demands that the Cubs cash in runners when they have the opportunity. Leaving runs on base in a tight game at American Family Field is a quick way to hand Milwaukee a win they will absolutely take.
- Bullpen management: Depending on how Peterson fares, the Cubs' relief corps will need to be ready to bridge any gap. Clean innings from the back end of the staff could be the difference in a one-run game.
Cubs vs. Brewers September 8 Prediction
This is a game that figures to be decided by a slim margin. Both Peterson and Misiorowski are capable of keeping the opposing offense in check, and divisional familiarity tends to compress scoring in September matchups like this one. The Cubs will need to be opportunistic, manufacture a run or two, and trust Peterson to give them a quality start. Expect a competitive, low-scoring game that goes down to the late innings. Cubs take this one, 3-2, but it will not come easy.
