Arizona Diamondbacks reliever Justin Martinez exited in the ninth inning against the Seattle Mariners on Monday night because of tightness in his pitching elbow. Martinez entered to start the ninth with the Diamondbacks leading 4-0 and struck out Jorge Polanco and Randy Arozarena to begin the inning.

Diamondbacks right-hander Justin Martinez has been placed on the 15-day injured list with a sprained ulnar collateral ligament in his pitching elbow.

DBacks' Merrill Kelly gets the ball to open the Mariners series and is coming off seven scoreless innings on one hit at Atlanta in his last start.
