Mariners general manager Jack Zduriencik continues to be busy making moves. After signing Erik Bedard and Aaron Heilman to one-year deals to avoid arbitration, Zdruiencik also announced that the Mariners have acquired right-handed reliever David Aardsma from the Boston Red Sox in return for minor league left-handed pitcher Fabian Williamson.
Aardsma was immediately placed on the 40-man roster giving the Mariners a full 40.
"Adding David to our roster gives us another quality bullpen arm," Zduriencik said in a press release.. "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 appeared in a career-high 47 games last season with the Red Sox. He finished 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 also missed some 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. The Red Sox had to designate him for assignment a few days back when the re-signed free agent outfielder/first baseman Mark Kotsay.
This will be 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).
Aardsma played collegiately at Rice and was a first round pick of the SF Giants (No. 22 overall) in the 2003 draft.
His other claim to fame is that he is listed as the first player in the baseball encyclopedia moving ahead of Hank Aaron.
As for the guy the Mariners gave up. Williamson is a 20-years-old and was taken in the 22nd round of the 2006 draft. He 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.
