The Tigers haven't changed their plans despite Jose Iglesias' recent injury. A bruised hand has kept the rookie out of the starting lineup for the past six games, though he has been used as a defensive replacement.
Peralta has been playing the outfield and taking at-bats with the Tigers' Instructional League team in Florida. He has yet to be tested with a fly ball in left field and did not make a putout in 10 combined innings this week. Peralta played the final two innings at shortstop Thursday, but it was believed to be as a precaution.
"I don't know for sure what they want me to do when I get there, but I know they want to see me in left field in Miami," he told the Free Press. "Maybe I'll get a fly ball in Miami."
The Tigers have not revealed if Peralta will be in the starting lineup in any of their final three games against the Marlins. The Marlins are starting three right-handed pitchers and Andy Dirks usually starts in left field against righties. The Tigers likely want to get a look at Peralta in the outfield before deciding whether to add him to their postseason roster.
