Garza had just completed three scoreless innings, but newly-acquired right-hander Justin Germano replaced him in the fourth inning.
During the top of the fourth inning, Garza could be seen in the dugout talking to pitching coach Chris Bosio and appeared to be flexing his wrist and stretching is right forearm. As a precaution, X-rays were taken but they came back negative.
Early concerns were that an injury could hamper the Cubs' efforts to trade Garza, but the cramp behind his right arm was the best possible scenario.
Garza has been in the midst of trade rumors since spring training with most of them heating up now that the July 31 non-waiver trade deadline is approaching. The most recent rumor had the Dodgers interested in acquiring Garza.
