DENVER -- Rockies starter Jon Gray left Friday night's game against the A's with an injury in the third inning.

Gray allowed five runs on four hits -- two of them homers -- and two walks, getting only seven outs before departing with the trainer.

After the game, manager Bud Black stated that Gray left after experiencing right elbow soreness and forearm tightness. Black attributed Gray's rough third inning to the issues he felt on the mound.

“The soreness impacted his pitching, yes,” Black said postgame. “[It] started to tighten a little as the game went on … that’s when we noticed his mannerisms, we knew something was up.”
