SEATTLE, May 17 (UPI) -- Franklin Gutierrez hit an RBI single in the ninth inning Sunday to boost the Seattle Mariners to a 3-2 win over the Boston Red Sox.

The winner was reliever David Aardsma (1-1).

Boston's J.D. Drew had two hits -- one a solo homer in the fourth.

Jason Varitek had one RBI and Green added two hits for the Red Sox, who have lost four of five.

The losing pitcher was reliever Ramon Ramirez (4-1).

Boston starter Justin Masterson yielded two runs and nine hits in 6 1/3 innings with no walks and six strikeouts.
