Mariners 2, Red Sox 1: Kevin Millwood worked six strong innings and Dustin Ackley singled in a pair as host Seattle took the rubber game from fading Boston.

Millwood (5-12) allowed one run on four hits while walking three and striking out three to snap a six-start winless streak. Four relievers combined to work the seventh and eighth and Tom Wilhelmsen finished up with his 24th save for the Mariners, who pushed back to within four games of .500 (67-71).

Cody Ross had three hits and the lone RBI for the Red Sox, who dropped eight of nine on their West Coast trip while being outscored 63-21.

Seattle broke through against Aaron Cook (3-9) in the fourth. Two singles sandwiched around a walk loaded the bases before Brendan Ryan popped out. Cook got the ground ball he needed from Ackley but it found a hole, shooting straight back through the box and into center field to score Eric Thames and Mike Carp.

Ross doubled home Jacoby Ellsbury in the sixth and Boston put a runner on in each of the last three innings, but could not push across the tying run.

Cook ended up going six innings and was charged with both runs on seven hits. The veteran right-hander is 0-4 in his last five starts.
