If Perez makes contact, steals bases, takes walks (not seen yet), covers ground...and hits .300, then he's a starter. I'll start calling him Brett Gardner.
Low-power hitters? How about Ty Cobb, Sam Rice, and Maury Wills. Walking Maury was like giving up a double. Rice hit about .325 until the Nats benched him because he could no longer move fast enough in the OF. He was about 43. And Cobb? If only...
I don't expect that Perez is a combination of Cobb, Rice, and Wills: point is you don't need power to win games.
