The Orioles announced Monday afternoon that they've acquired right-hander David Pauley from the Red Sox in exchange for right-handed reliever Randor Bierd.
Pauley, who went 14-4 with a 3.55 ERA in 25 starts with Triple-A Pawtucket in 2008, was removed from Boston's 40-man roster last week to make room for John Smoltz. Since being selected by the Padres in the eighth round of the 2001 First-Year Player Draft, he's found most of his success at the Minor League level.
In six appearances (two starts) for Boston in 2008, Pauley was 0-1 with an 11.68 ERA. While recording a professional career-high 14 wins and completing 147 innings for Triple-A Pawtucket last season, he registered 103 strikeouts and issued 41 walks.
Bierd, who was acquired from Detroit in the 2007 Rule 5 Draft, went 0-2 with a 4.91 ERA in 29 appearances for Baltimore. The 24-year-old right-handed reliever struggled with his control, registering 25 strikeouts and issuing 19 walks in 36 2/3 innings. He hadn't been in the Majors before the 2008 season.
