PITTSBURGH (AP) -- The Pittsburgh Pirates placed Corey Hart on the 15-day disabled list Wednesday and promoted pitcher Chris Volstad to take his place on the active roster.
The 33-year-old Hart, who's made seven starts at first base and three in right field during his first season in Pittsburgh, is out because of a left shoulder impingement.
Volstad, a right-hander, allowed two or fewer runs in six of his past seven starts for Triple-A Indianapolis. The 28-year-old was 5-2 with a 3.43 ERA in 76 innings over 14 appearances (12 starts). He will pitch out of the bullpen for Pittsburgh.
