In his career at AAA prior to the injury, Barthmaier had put up a 3.53 ERA in 79 innings over 17 starts, with an 8.1 K/9 and a 3.3 BB/9 ratio. In his time with AA this year, Barthmaier really struggled. He pitched just three innings in five appearances, with a 12.00 ERA and a 2:5 K/BB ratio.
Barthmaier is 26, so the hope coming in to the season was that he could recover and provide the Pirates with some pitching depth out of AAA this season.
UPDATE 11:58 AM: According to Dejan Kovacevic, Diego Moreno has been activated from the disabled list. Good news, as Moreno is one of the more interesting relief prospects to watch in the Pirates’ system. Moreno missed 22 games with a strained rotator cuff.
