Don Kelly hit a sacrifice fly with the bases loaded in the bottom of the 9th inning to give the Tigers a 5-4 walk-off win in today's game.  The win gives the Tigers a 2-0 advantage over Oakland in their best-of-five American League Divisional Series.Kelly came in as a pinch-runner in the previous inning and scored the tying run on a wild pitch.  Often times in the postseason, it's the role players that shine on the biggest stage.  After Omar Infante singled with one out in the 9th, Miguel Cabrera hit a bloop single to advance Infante to third.  The A's opted to intentionally walk Prince Fielder and pitch to the weak-hitting Kelly.  After taking a first-pitch strike from A's closer Grant Balfour, Kelly lifted a fly ball to right field on the next pitch  that was deep enough for the speedy Infante to tag up and score the winning run.  The Tigers and A's will resume their playoff series in Oakland on Tuesday night.  With a 2-0 advantage in the best-of-five series, the Tigers need to win just one of the next three in Oakland to advance to the American League Championship Series. Today's game wasn't pretty, but it ended pretty good for the Tigers and their legion of fans.  For complete details on the game, visit
