Brewers vs Cubs Prediction: Shota Imanaga Dominates at Wrigley Field

The Milwaukee Brewers travel to Wrigley Field Monday night to open a three-game series against the Chicago Cubs, with first pitch at 7:40 p.m. ET on MARQ and Brewers.TV. This NL Central rivalry always delivers compelling baseball, and in 2026, both clubs have been among the better teams in the division. Chicago sits at 29-17, currently leading the NL Central. Milwaukee is right behind them at 26-17, just three games back. Every series between these two clubs has serious implications.

The storyline for Monday night is simple: Chicago sends one of the best left-handed starters in baseball to the mound in Shota Imanaga, who has been electric this season. Milwaukee counters with Brandon Sproat, who is making his way through a rocky early stretch. The pitching mismatch is real, the Cubs are the better team on paper, and Wrigley Field will be packed for a May rivalry game with playoff implications on the line.

Chicago Is a Significant Favorite, and the Numbers Support the Price

The Cubs open as -162 moneyline favorites, with Milwaukee at +136 to +140 depending on the book. The run line has Chicago at -1.5 at +118, which is an intriguing number given the mismatch on the mound. The total is set at 10.5, with even money on the over and the under at -102. The high total reflects the offensive capabilities on both sides, though Imanaga’s presence suggests the Cubs’ half of the run total will be suppressed.

The Cubs are drawing 83% of the money on this game, and it is easy to see why. When Imanaga is pitching at Wrigley, Chicago has a legitimate ace capable of shutting down any lineup in baseball. The market is pricing this correctly — -162 is steep but justified given the quality of the starting pitcher. The interesting play for value hunters is actually the Cubs -1.5 run line at +118, which gives you a better price for an outcome that Imanaga makes increasingly likely.

Brandon Sproat enters with a 1-2 record and a 5.75 ERA through six starts for Milwaukee, which tells you everything you need to know about the pitching disparity. He has been better in his more recent outings — the Brewers are 5-1 against the spread in his six starts — but his ERA reflects a pitcher who is still working through command and consistency issues. Against a Cubs lineup that is currently one of the better offenses in the National League, Sproat will need his best stuff.

Imanaga’s Brilliance, Chourio’s Upside, and the Battle at Wrigley

Shota Imanaga has been one of the most consistent starting pitchers in baseball this season. The left-hander is 4-3 with a 2.32 ERA through nine starts, striking out 59 batters in 54.1 innings. His WHIP of 0.90 is elite — fewer than one baserunner per inning, which means Milwaukee’s offense will have to manufacture runs the hard way if they are going to score against him. Imanaga’s arsenal plays particularly well at Wrigley, where the wind and the big outfield make his ball-in-play approach especially effective.

The Cubs’ lineup behind Imanaga is also well-constructed for the moment. Alex Bregman at third base has been productive with a .998 OPS projection and consistent contributions across the lineup. Nico Hoerner leads the team in projected plate appearances and has been excellent at making contact and getting on base. Seiya Suzuki, Ian Happ, and Pete Crow-Armstrong give the Cubs three legitimate run-scoring threats in the middle and lower portions of the order. Chicago scores at a high level because they do not have automatic outs in their lineup — there are productive hitters from top to bottom.

For Milwaukee, the offensive burden falls heavily on Jackson Chourio. The young outfielder, number 11 for the Brewers, has been the team’s most dynamic offensive weapon this season. He is projected with one of the best run-scoring probabilities in the game on Monday, and his combination of speed, athleticism, and raw power makes him a genuine threat every time he steps to the plate. Chourio can change a game with one swing, and even against Imanaga, he represents the kind of bat that a pitcher must account for at all times.

William Contreras behind the plate has also been one of Milwaukee’s most consistent contributors. He is projected favorably for run production and represents the kind of clutch bat that can make a manager’s day in a tight game. The Brewers have enough offensive pieces to be competitive — they are not a team that simply rolls over. But Sproat needs to give them enough innings to keep the game close, and that has been the challenge all season.

The head-to-head history between these clubs this season has been tight, which makes sense for two division rivals with similar overall quality. However, Imanaga’s individual matchup advantage over Sproat is the decisive factor. Even in a game where Milwaukee’s hitters are capable of tagging a quality starter, Sproat’s 5.75 ERA suggests the Cubs will find a way to score multiple runs before he can settle in. Wrigley’s atmosphere in May, with both clubs pushing for a division title, adds the kind of energy that benefits the home team.

Prediction and Best Bet

This game comes down to one thing: can Milwaukee score enough early runs against Imanaga to keep Sproat’s mistakes manageable? The answer is probably not. Imanaga is too good and too consistent to give up the kind of early lead that would let Sproat navigate a high-scoring affair. Chicago wins this game, and they win it behind their ace.

• Prediction: Chicago Cubs 6, Milwaukee Brewers 3
• Best Bet: Chicago Cubs -1.5 (+118)

The Cubs -1.5 at +118 is the best bet on the board in this game. Imanaga’s ERA and strikeout rate make him the kind of pitcher who regularly enables his team to win by multiple runs. Sproat’s struggles against quality lineups mean the Cubs’ bats do not need to do anything special — they just need to grind out a normal day against a struggling starter. Chicago covers the run line and provides solid value at plus money.
