BOSTON (AP) -- Toronto starter Henderson Alvarez left Monday night's game against Boston in the sixth inning with an injury.
Alvarez threw three pitches to the leadoff hitter, Adrian Gonzalez, before the trainer and manager John Farrell came to the mound. He walked off a few minutes later with the trainer and was replaced by right-hander Jason Frasor.
It was the second time the trainer and Farrell had gone to the mound. They came out with one out in the third inning.
There was no immediate word about the injury.
The Blue Jays were leading 7-5.
