Carson Smith tossed one inning in relief for the Red Sox in yesterday’s loss to the Oakland A’s, giving up a home run to Khris Davis. After he left the game, he was apparently mad at himself, and he tossed his glove in frustration. That’s a normal and fine reaction, but Smith injured himself doing so, and according to Red Sox president of baseball operations Dave Dombrowski, Smith’s injury might be very quite serious.

Smith suffered a subluxation of the right shoulder in the glove-rage incident, which is a scientific way to say he dislocated his arm out of its socket. He was placed on the 10-day DL, and the Red Sox called up a left-handed reliever from their Triple A team to replace Smith. Boston’s bullpen is one of the AL’s better relief units, and Smith has appeared in 18 games this season, posting a 3.77 ERA.
