Prince Fielder and Delmon Young hit two-run home runs to help the Detroit Tigers to an 8-7 victory over the Kansas City Royals on Saturday at Comerica Park.  Austin Jackson and Gerald Laird each had three hits and an RBI as well, while Doug Fister won for just the second time this season.  Jose Valverde allowed three runs in the ninth, but got the final out of the game with the tying run at second base.  Detroit goes for a sweep in the three game series on Sunday afternoon.
