Gabriel Castellanos

Organization Prospect Rankings

• 
  Ranked Miami Marlins #20 prospect in 2015
  The tall and slender Castellanos remains raw but has plenty of projectability. Through two Dominican Summer League seasons, he had trouble finding the zone, so the Marlins were prepared to keep him in the DSL a third season in 2013. However, former minor league pitching coordinator Wayne Rosenthal encouraged the club to bring Castellanos to the U.S., and the added instruction proved beneficial. While his stuff is live, he struggled with command at short-season Batavia in 2014. Nevertheless, the Marlins are excited. Castellanos has an easy delivery and good sink on the fastball, which sits 91-93 mph. Those figures should rise as he adds strength. He also throws an inconsistent slider that has flashed two-plane break at its best. Among the priorities for him in 2015 are gaining consistency with the slider and additional touch on the changeup. Castellanos will head for low Class A Greensboro in 2015.
