DETROIT -- Mike Aviles hit a grand slam in the ninth inning that lifted the Cleveland Indians to a 4-0 win over the Detroit Tigers on Sunday.
The AL Central leaders had won seven straight against second-place Cleveland.
The Tigers won the season series 15-4, a string of success that has helped them build a 7 1/2-game cushion in the division with a month left in the regular season.
Detroit rested banged-up star Miguel Cabrera for a second straight game. Joe Smith (6-2) got the win after giving up one hit and a walk in the eighth, keeping the Tigers scoreless after Danny Salazar's strong start.
Detroit tried to rally in the ninth, but a tough break on the bases proved costly.
Chris Perez gave up a one-out double to Omar Infante, who was hit by Alex Avila's liner for the second out. The right-hander let No. 9 hitter Ramon Santiago extend the inning with a single, and a passed ball put the runners in scoring position before Andy Dirks grounded out to end the game.
Detroit's Justin Verlander extended his winless streak to five outings, but held a team scoreless for the first time since a seven-inning start on July 14 against Texas.
