ARLINGTON — Rangers right-handed pitcher Cal Quantrill exited Saturday’s 6-2 win vs. the Toronto Blue Jays at Globe Life Field in the second inning with right lat tightness. 

Quantrill pitched a scoreless first inning and recorded the first out of the second on an 87.8 mph fastball — a pitch six miles per hour slower than his usual heater — before a mound visit. He exited the game after a brief chat with Rangers manager Skip Schumaker, pitching coach Jordan Tiegs and trainer Matt Lucero.

“No real update other than he’s going to get an MRI tomorrow,” Schumaker said. “I’m not sure the extent of the injury.”

The 31-year-old dealt with back tightness in his previous start against the Arizona Diamondbacks but said Thursday that he was “good to go” for Saturday’s game. 

He’s been one of the league’s better starting pitchers for nearly two months now and has a 2.87 ERA in 109 2/3 innings this season.
