Peralta came in with his own expectations. Cabrera's defense this season has exceeded them.
"That's what a lot of people think -- they worry about the difference for him," Peralta said. "But he worked really hard in Spring Training. I mean, it surprised me, too. He's doing really good with defense. Nobody was waiting for that, but he's unbelievable."
The Tigers will have to decide soon after the season ends whether they want to keep Cabrera and Peralta as a tandem. Detroit has a $6 million option for Peralta for next season but can buy out his contract for $500,000.
