Perez will likely fall into the role of utility infielder for the club, as the team has been happy with the play of Omar Infante since he moved into the everyday lineup.
The need arose to upgrade the infield when Placido Polanco suffered a separated shoulder. Polanco isn't expected to return until later in September.
Robinson was hitting .288 with one home run and 47 RBI. He won't have to travel far, as he'll be moved to the Daytona Cubs, Chicago's Florida State League club. The Tigers drafted Robinson in the third round two years ago, but he didn't play nearly as well as the club had hoped, and he likely projected to be more of a backup than an everyday player.
Meanwhile, Andrew Miller debuted in Lakeland on Sunday. He was originally supposed to debut on Saturday, but the game was pushed back and was played as part of a doubleheader on Sunday. Miller pitched an inning of scoreless relief, striking out two batters and getting a weak groundout.
While nothing is official, Miller is still expected to make his big league debut in September when the rosters expand.
