SEATTLE — Mitch Haniger hit a grand slam in the sixth inning, two batters after Arizona ace Zac Gallen left because of tightness in his right hamstring, and the Seattle Mariners beat the Diamondbacks 6-1 on Friday night.
Gallen (3-2) walked Josh Rojas to lead off the sixth, then was pulled in the middle of Julio Rodríguez’s subsequent at-bat.
“Just a right hamstring spasm and I think we really dodged a bullet,” Diamondbacks manager Torey Lovullo said. “Credit him, it’s hard to pull back in those situations and understand what you body is feeling and call out your catcher. I think he’s hopefully going to be fine.”
Rodríguez went on to single off Scott McGough, and Cal Raleigh walked to load the bases for Haniger, who hammered a 389-foot shot to left-center on a full-count fastball.
