The Pittsburgh Pirates are calling up top pitching prospect Bubba Chandler, who will make his major league debut this weekend against the Colorado Rockies, according to a report from Alex Stumpf of MLB.com.
Chandler, who is the No. 7 overall prospect in baseball and the top amateur arm in the game, is thought to be used as a reliever at the outset this season, but as a starter in the rotation long-term.
