The Chicago Cubs have been on a roll to start the season, but they appeared to hit a bump in the road this past Sunday against the Milwaukee Brewers when star pitcher Shota Imanaga had to exit the game early due to injury.

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.

Chicago's bullpen subsequently allowed a pair of inherited runners to score, impacting Imanaga's line for the worse. The book closed on his afternoon with him surrendering two runs on four hits and a walk. He also struck out four of the 22 batters he faced.
