The Chicago Cubs are going to be cautious with Shota Imanaga while the left-hander recovers from his first hamstring injury.Imanaga was placed on the 15-day injured list on Monday with a mild left hamstring strain.

Shota Imanaga’s recovery and rehab process will be measured in weeks, not days, as the Chicago Cubs cautiously handle the injury.

Given the way Shota Imanaga walked off the field in Milwaukee on Sunday, Cubs manager Craig Counsell felt a trip to the injured list was the likely outcome for the left-handed starter. That step officially arrived for Imanaga prior to Monday’s game against the Giants.
