According to MLB.com insider Alex Stumpf, the Pirates are planning to call up the top pitching prospect in baseball, Bubba Chandler. Armed with a high-90s fastball, Chandler is ranked as the No. 7 prospect in the game, according to MLB Pipeline, and is the top pitching prospect in baseball.

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.
