Matthew Boyd (3-4) allowed two hits in five-plus innings for the Tigers. His first scoreless outing of the season came on a hot day in which Detroit outfielder Niko Goodrum had to leave the game because of heat exhaustion.
Before leaving the game, Goodrum made a contribution in the second, beating out an infield hit and then going to third on a single by John Hicks. JaCoby Jones grounded into a double play, but the run came home to put the Tigers up 1-0.
McCann broke the game open an inning later with a drive to left for his third career grand slam.
