Perez agreed to a minor league contract with the Pirates on Friday that includes an invitation to spring training, Adam Berry of MLB.com reports.
The 26-year-old speedster split time between the Triple-A affiliates of the Astros and Rays organizations, batting .256 with 20 stolen bases between the two stops. For a guy with as much speed as he possesses, Perez doesn't walk all that much, so until he starts to hit for a higher average, he'll continue to act as organizational outfield depth.
