DETROIT -- Jose Alvarez pitched six impressive innings in his major league debut, making the most of a one-day audition with the Tigers in Sunday's 4-1 victory over the Cleveland Indians.
He was called up to make this start when Anibal Sanchez's shoulder acted up.
Don Kelly hit a tiebreaking three-run homer in the sixth for the first-place Tigers, who completed a three-game sweep of Cleveland and lead the AL Central by 5 ½ games over the Indians.
Alvarez (1-0) held Cleveland hitless until Ryan Raburn's fifth-inning homer. He allowed three hits and a walk and struck out seven. Drew Smyly pitched two innings of relief. Joaquin Benoit finished for his third save.
Justin Masterson (8-5) allowed four runs in seven innings. He gave up a walk to Miguel Cabrera and a single to Prince Fielder to start the sixth. One out later, Kelly lifted a drive over the wall in right field. Alvarez had thrown his last pitch by that point, but Kelly's hit made him the pitcher of record.
