The Pittsburgh Pirates have sent Oneil Cruz to Triple-A Indianapolis to begin the season.

ESPN's Kiley McDaniel ranks Cruz as the No. 13 prospect in baseball.

"It was a development decision," Derek Shelton said. "There's still room for development and still things that we feel he can maximize on."

Cruz, 23, played 63 games at Double-A Altoona and six with Indianapolis before being called up to the majors at the end of last season.
