The Pittsburgh Pirates will call up right-handed pitcher Bubba Chandler and add him to the big-league staff on Friday, MLB.com reports.

Right-hander Bubba Chandler was called up by the Pirates on Wednesday ahead of their three-game series against the Blue Jays, which starts on Friday.

Chandler is expected to initially work in a bulk bullpen role. He 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 in 100 innings pitched this year for Indianapolis.
