Organization Prospect Rankings
Perez signed in 2008 but had a largely unremarkable pro career until 2014, when he led the organization's minor leaguers with 30 steals at low Class A. In 2015, he was second in the minors with 71 steals, just short of the record for a Marlins' farmhand (Quincey Foster, 73 in 1998 for high Class A Kane County). He got his first big league promotion in July, used as a pinch-runner. A shortstop when he signed, the Marlins have tried to exploit his one above-average tool--speed, for which he grades an 80 on the 20-80 scout scale--by expanding upon his versatility. Scouts say his speed makes him an asset in center field, and he can also play short, second and third base, with his solid-average arm serving well at those spots. He played center, short and second in the Arizona Fall League. He's an average defender who can outrun misreads in the outfield. At bat, Perez has little power impact, with an occasional double, but he uses his speed well. Perez has a good short game, with a quick, downward-slashing swing that he uses to lash singles around the field. He's also a good bunter. Perez profiles as a utility man or pinch-runner.
