TORONTO, ONT (1660 THE FAN) - Boy, this one started out on the right foot.  Back to back home runs by Miguel Cabrera and Prince Fielder in the 1st inning staked the Tigers to an early lead...but it didn't last long.  Toronto got one back in their half of the 1st, then the Blue Jays got to Rick Porcello for four more runs in the 4th, three of them on a bases-clearing double by Jeff Mathis.  Final score - Toronto 8, Detroit 3.  The Tigers try to regroup Saturday afternoon, with broadcast time on AM 590 WKZO set for 12:40 pm.
