Originally selected by Baltimore in the sixth round of the 1999 First-Year Player Draft, Bedard made his Major League debut with the Orioles in 2002. He won a career-high 15 games with the Orioles in 2006 while posting a 3.76 ERA in a career-high 33 starts. Bedard ranked third in the American League with 221 strikeouts while going 13-5 with a 3.16 ERA in 28 starts during his final season with Baltimore in 2007. He also ranked fourth in the league in ERA in 2007 and allowed the fewest hits per 9.0ip that season (6.973).
"Erik Bedard is a quality major league starting pitcher and we are pleased to add him to our club and starting rotation," said Pirates GM Neal Huntington.
In his Major League career, Bedard has gone 11-10 with a 3.35 ERA during the month of May and 11-6 with a 2.64 ERA during the month of June.
After being traded to Seattle in February 2008, Bedard spent two seasons with the Mariners before missing the entire 2010 campaign due to shoulder problems.
To make room for Bedard on the active roster, the Pirates have designated catcher Jason Jaramillo for assignment.
