The Chicago Cubs team president has high demands of the team's pitching unit despite a significant injury to Shota Imanaga.

Imanaga, 31, strained his left hamstring when he went to cover first base in the sixth inning of Sunday's 4-0 loss at Milwaukee.

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.
