Baseball’s top pitching prospect is getting called up to the majors. A person familiar with the decision told The Associated Press that the Pittsburgh Pirates have decided to promote 22-year-old right hander Bubba Chandler ahead of their game Friday against the Colorado Rockies. The person spoke to the AP on condition of anonymity because the roster move was not yet official. Chandler got off to a hot start in Triple-A this year but has stumbled lately and is currently 5-6 with a 4.05 ERA this year for Indianapolis. The Pirates are shuffling their pitching rotation after sending veteran left-hander Andrew Heaney to the bullpen.
