Zduriencik announced today that the Mariners have acquired right-handed pitcher David Aardsma from the Boston Red Sox in exchange for minor league LHP Fabian Williamson.
With this trade, the Mariners 40-man roster is now full.
"Adding David to our roster gives us another quality bullpen arm," said Zduriencik. "He has over three years of Major League experience and is a former first-round draft pick. We are excited to give him the opportunity to help bolster our bullpen."
Aardsma, 27, pitched in a career-high 47 games last season with the Boston Red Sox. He went 4-2 with a 5.55 ERA (30 ER, 48.2 IP), averaging 9.06 strikeouts per 9.0 innings (49 K, 48.2 IP). He missed time during the season with two stints on the disabled list, July 20-Aug. 8 and Aug. 24-Sept. 10 with a strained right groin.
Entering his seventh professional season, Aardsma has compiled a career 10-3 record with a 5.29 ERA (85 ER, 144.2 IP) in 128 games (all in relief) with San Francisco (2004), Chicago Cubs (2006), Chicago White Sox (2007) and Boston (2008).
The product of Rice University was originally selected in the first round (22nd overall) of the 2003 June draft by the San Francisco Giants. A native of Denver, CO, Aardsma is the first player listed in the Baseball Encyclopedia, ahead of Hank Aaron.
Williamson, 20, went 4-3 with a 4.10 ERA (24 ER, 52.2 IP) in 11 starts for the Pulaski Mariners (short-season A) last season. He was selected by the Mariners in the 22nd round of the 2006 June draft out of Kennedy High School (Granada Hills, CA).
