TORONTO - Miguel Cabrera and Prince Fielder smacked back-to-back home runs in the first inning. That was the extent of the offensive fireworks for the Tigers, though, as they lost at Toronto 8-3 to open up a 3-game series. Starting pitcher Rick Porcello was tagged with the loss, giving up 5 runs and 6 hits in 6 innings of work; he drops to 7-6. Annibal Sanchez will make his Tigers debut when he takes to the hill this afternoon; he and Omar Infante were obtained in a trade with Miami earlier this week.
