Arizona ace Zac Gallen leaves in 6th inning against Seattle with right hamstring tightness

Arizona Diamondbacks ace Zac Gallen left his start against the Seattle Mariners on Friday night after feeling tightness in his right hamstring, but manager Torey Lovullo said he hopes Gallen won't miss any time. Lovullo said after the D-backs' 6-1 loss to Seattle that Gallen felt a spasm in his hamstring and the decision to pull him was precautionary. Gallen walked Mariners third baseman Josh Rojas leading off the sixth inning and then was removed by Lovullo in the middle of an at-bat against Julio Rodríguez.
