Teheran left Friday's game with right lat tightness and is day-to-day.
He exited after chasing down a dribbler to the left side of the mound, but considering the injury was to his back/shoulder muscles, he may have suffered the injury while taking a hard swing during an earlier at-bat. Teheran tossed four shutout innings, allowing three hits while walking two and striking out three before leaving with zero outs in the fifth inning. Consider him questionable to make his next scheduled start July 28 (Thursday) against the Phillies.
