Prior to the injury, Imanaga had been a bright spot in the Cubs’ rotation, posting a 3-2 record with a 2.82 ERA over eight starts. His performance included 34 strikeouts in 44.2 innings, providing stability to a rotation that has faced challenges this season.

In a corresponding move, the Cubs have recalled right-handed pitcher Gavin Hollowell from Triple-A Iowa to bolster the bullpen during Imanaga’s absence. Hollowell’s promotion comes at a crucial time, as the Cubs aim to maintain their competitive edge in the National League Central division.

The Cubs’ pitching staff has been further tested by recent injuries to other key contributors. Javier Assad, who was recovering from a left oblique strain, suffered a setback during a rehab start at Triple-A, delaying his anticipated return to the rotation . Additionally, reliever Adbert Alzolay is on the 60-day injured list with a right flexor strain and is expected to undergo arm surgery, potentially sidelining him for the remainder of the season .

With these injuries mounting, the Cubs will need to rely on their remaining healthy pitchers and explore potential trade options to reinforce their rotation as the season progresses. The team’s ability to navigate these challenges will be crucial in their pursuit of a playoff berth.
