Bumgarner's left arm showed no structural damage after undergoing in MRI on Monday, Nick Piecoro of the Arizona Republic reports. The left-hander is on track to make his next scheduled start Friday at home against the Dodgers.

EDGE Analysis

Bumgarner was seen talking with trainers during his first start of the season but stayed in the game. After manager Torey Lovullo noticed Bumgarner's velocity down a couple of ticks, the team opted to have the arm checked out and chalked it up to "fatigue." The pitcher plans to throw a between-starts bullpen this week in preparation for Friday's start, his second time facing the Dodgers. In the first start, Bumgarner allowed five runs in four innings.
