The Pirates have outrighted Andy Oliver off of the club's 40-man roster, the team announced via press release. Oliver is a 26-year-old southpaw.
Oliver has not seen MLB action with the Pirates, and only made brief appearances with the Tigers in 2010-11. In 124 1/3 Triple-A innings last year, Oliver posted a 4.05 ERA with 10.0 K/9 and 8.1 BB/9. Obviously, he'll need to solve those control issues before having a chance at making an impact at the MLB level.
