PITTSBURGH -- Baseball's top pitching prospect is getting called up to the majors. The Pittsburgh Pirates have decided to promote 22-year-old right hander Bubba Chandler ahead of their game Friday against the Colorado Rockies, a person familiar with the decision told The Associated Press on Wednesday.

On Tuesday, he debuted with Double-A Altoona, and at 19 years and 117 days old, he became the youngest player to suit up for the Curve.
