Red Sox, Orioles swap right-handers

Pauley heading to Baltimore in deal; Bierd joining Boston

Looking to add some starting pitching depth to their organization, the Orioles have dipped into Boston's surplus of arms.

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.
