MLB: Detroit 13, Boston 12 (11 inn.) DETROIT, April 8 (UPI) -- Alex Avila smashed a two-run homer in the bottom of the 11th inning Sunday, rallying the Detroit Tigers to a wild 13-12 win over Boston. The Tigers staged two last-chance comebacks in the marathon contest. They trailed 10-7 heading in the bottom of the ninth and rallied to tie it on Miguel Cabrera's three-run homer. Then in the top of the 11th, the Red Sox scored twice on RBI from Nick Punto and Dustin Pedroia, taking a 12-10 lead. But Detroit rallied again in the bottom of the frame off Mark Melancon (0-2) when Delmon Young drove in a run with a sacrifice fly and Avila followed by smacking a knuckle-curve ball into the right field stands with two outs. Cabrera went 3-for-5 with five RBI, Austin Jackson added four hits with three runs scored and Jhonny Peralta stroked a three-run double for the Tigers, who swept their season-opening series from the Bosox. Duane Below (2-0) got credit for the win after retiring one batter in the 11th. Punto ended with three hits and three RBI. Adrian Gonzalez hit a two-run homer for the Red Sox, who have started 0-3 for the second straight season.
