Diamondbacks' Zack Greinke: Leaves Tuesday with undisclosed injury

Greinke left Tuesday's game prior to the top of the third inning with an undisclosed injury.

Analysis:

He came out to warm up for the start of the third inning, then ran into the dugout tunnel before coming back out with the training staff and threw one warmup pitch before exiting. It was a bizarre exit to say the least, and it sounds like his back may have tightened up, as he was seen touching his back before leaving. We will provide more information when the team releases his official status.
