CHICAGO -- The Chicago Cubs placed left-handed starter Shota Imanaga on the 15-day injured list Monday with a left hamstring strain, a day after he got hurt when going to cover first base.
Chicago made the move before the opener of its series against San Francisco. Right-hander Gavin Hollowell was recalled from Triple-A Iowa.
Imanaga got hurt during Sunday's 4-0 loss at Milwaukee after going to cover first base on a potential double play in the sixth inning of what was then a scoreless game. The Japanese pitcher had exited his previous start with cramping in each of his legs.
