Shota Imanaga's left hamstring strain during the Chicago Cubs' 4-0 loss to the Milwaukee Brewers raises concerns for an already beleaguered pitching rotation. Imanaga, who previously experienced leg cramps, felt discomfort while covering first base on a double play attempt. Cubs manager Craig Counsell indicated that further imaging would be necessary to assess the injury. With Imanaga potentially joining Justin Steele and Javier Assad on the injured list, Chris Flexen or Cade Horton may be called up to fill the gap.

The Cubs also faced injury concerns with star outfielder Kyle Tucker, who appeared to tweak his hip during a play but remained optimistic about his availability for the upcoming series against the San Francisco Giants. The Brewers, too, dealt with injuries as Sal Frelick exited with left knee discomfort. With the season's demands escalating, teams must strategically navigate these injury challenges.
