Gonzales left Wednesday's start against the Rays after being struck by a line drive around his left forearm during the first inning, Shannon Drayer of 710 ESPN Seattle reports.
The left-hander was struck by a 109-mph line drive off the bat of Harold Ramirez, who was the third batter of the game. Gonzales recorded one out and allowed a run on a walk and a hit before exiting the contest. The Mariners will likely update his status later Wednesday.
