The Pirates claimed Chris Leroux off of waivers and designated Brian Bass for assignment, according to the team. Leroux, a 26-year-old right-hander, appeared in 17 games for the Marlins this year. He struck out 18 batters in as many innings, though he also walked 11. The Montrealer posted a 6.28 ERA in three minor league stops this year, but his strikeout (7.2 K/9) and walk (2.5 BB/9) numbers were good.
Bass, a 28-year-old righty, spent most of the season in the bullpen at Triple A Indianapolis, where he had strong numbers. In 69 innings, he posted a 3.26 ERA with 6.9 K/9 and 3.0 BB/9, though he struggled in 7.1 major league innings this year. He cleared waivers when the Pirates designated him for assignment earlier in the season.
