Shota Imanaga Takes the Mound as Cubs Host Brewers in Key Series

Shota Imanaga takes the mound Monday night at Wrigley Field with the Chicago Cubs hosting the Milwaukee Brewers in a critical NL Central matchup. The left-hander enters with a 4-3 record, a 2.32 ERA, and a microscopic 0.90 WHIP across 54.1 innings this season.

Chicago sits at 29-18 overall and a dominant 18-5 at home, making Wrigley one of the toughest venues in baseball this May. Milwaukee arrives at 26-18 but just 11-9 on the road, trailing the Cubs by 1.5 games in the division.

Why Imanaga’s Start Matters for the Cubs

Imanaga has been the most reliable arm in a rotation that has dealt with inconsistency behind him. His 0.90 WHIP ranks among the National League’s best, and his 59 strikeouts against just 13 walks reflect elite command for a pitcher in his second MLB season. The Cubs’ offense has given him plenty of support at home, where Chicago is averaging over five runs per game in its 18-5 Wrigley stretch.

Breaking down the advanced metrics, Imanaga’s ability to limit free passes has been the foundation of his success. A 2.3% walk rate would place him in the top 10% of the league if maintained over a full season. His ground-ball tendencies also play well in a ballpark where fly balls can carry into the bleachers on warm nights.

Brewers Bring a Dangerous Lineup Despite Injuries

Milwaukee’s pitching staff is navigating significant absences. Brandon Woodruff remains on the 15-Day IL, and the Brewers’ bullpen has been stretched thin with multiple relievers sidelined. Still, Milwaukee’s lineup has enough firepower to challenge any starter, and the Brewers have played competitive baseball on the road all season.

The Cubs’ own injury list is worth monitoring. Jaxon Wiggins landed on the 7-Day IL on May 17, and Caleb Thielbar joined him on the 15-Day IL the same day. J.B. Bukauskas also went on the 7-Day IL on Monday, thinning Chicago’s pitching depth heading into a grueling stretch of the schedule.

Key Developments

• Imanaga has pitched at least six innings in five of his last seven starts, providing consistent length for a taxed Cubs bullpen.
• The Cubs won their most recent game 2-1 at Minnesota on May 16, snapping a brief two-game skid that included losses to San Diego and Atlanta.
• Milwaukee’s 18-5 road record in away games contrasts sharply with its 11-9 mark away from American Family Field, highlighting a split that could matter in a tight division race.
• Chicago’s 29-18 start is its best through 47 games since 2016, the year the franchise last won a World Series title.
• Rob Zastryzny and Jeff Brigham are both on the 60-Day IL, leaving the Cubs without two arms who contributed during the 2025 campaign.

What’s Next for the Cubs Rotation

After Imanaga’s start, the Cubs will need to lean on their depth as the schedule intensifies. Richard Sproat, who carries a 5.75 ERA into the series, represents a clear drop-off in performance behind the staff ace. Chicago’s front office may need to explore the trade market if Wiggins and Thielbar miss extended time.

The Brewers series opens a critical three-week stretch in which Chicago faces multiple divisional opponents. How Imanaga performs Monday could set the tone for whether the Cubs maintain their NL Central lead or allow Milwaukee to close the gap. His first-pitch efficiency and ability to navigate the middle of Milwaukee’s order will be the deciding factors.

Looking at the broader picture, Imanaga’s emergence as a legitimate frontline starter has been one of the best developments of Chicago’s season. A year after transitioning from Nippon Professional Baseball, the 31-year-old has validated the Cubs’ decision to invest in his posting. If he keeps the WHIP under 1.00 through the summer, an All-Star selection in Arlington becomes a realistic possibility.
