Wilson Betemit capped Detroit’s three-run eighth inning with a tiebreaking RBI double against his former team, leading the Tigers to a 5-4 victory over the Kansas City Royals on Wednesday.

Austin Jackson went 4 for 4 and scored three times for the AL Central-leading Tigers, who have won seven of 10. Cabrera added two hits and Jose Valverde worked the ninth for his 40th save in 40 chances.

Eric Hosmer had a pair of solo homers for Kansas City, which has dropped four of six. The Royals traded backup C Matt Treanor to Texas during the game. Treanor has been sidelined with a concussion since July 30.
