Turnbull had nine strikeouts, relying heavily on his fastball but mixing in a strong slider to keep Seattle shut down. He threw 117 pitches, including 77 strikes.
Mitch Haniger was the closest to a hit for the Mariners, flying out to the wall in center field in the fourth inning. Haniger was also robbed of a hit by a diving stop from third baseman Jeimer Candelario leading off the seventh. The ball was recorded at 108 mph off Haniger’s bat, but Candelario snagged the one-hopper and made a strong throw to first base.
Turnbull completed the eighth no-hitter in Tigers’ history, and the first since Justin Verlander on May 7, 2011, against Toronto. Tuesday’s game marked the first time Turnbull pitched more than seven innings in 49 career starts.
The others to throw no-hitters this season were San Diego Padres right-hander Joe Musgrove against the Texas Rangers on April 9, Chicago White Sox right-hander Carlos Rodon against the Cleveland Indians on April 14 and Cincinnati Reds left-hander Wade Miley against the Indians on May 7.
There have been 10 games this season in which a pitcher took a no-hitter into at least the seventh inning, according to ESPN Stats & Information research.
