Seattle, WA (Sports Network) - Clay Buchholz worked seven crisp innings and Victor Martinez drove in a pair of runs to lead Boston past Seattle, 5-1, to complete a three-game sweep.
Buchholz (16-7) yielded a lone run on four hits while walking three and fanning six for the Red Sox, who have won four in a row.

David Pauley (2-8) pitched well but took the loss after yielding a pair of runs -- one earned -- on six hits with two walks and four strikeouts over six frames for Seattle, which has lost seven straight.
Russell Branyan clubbed a solo home run to right field with two outs in the first inning to put the Mariners on top.
Seattle had runners at second and third with nobody out and again with two outs in the second but could not score. The complexion of the inning changed when Casey Kotchman was picked off at third for the first out.
Adrian Beltre's home run into the upper deck in left field tied the game in the fourth.
The Red Sox took the lead for good in the sixth when David Ortiz doubled with one out, moved to third on a Beltre fly out and scored when Chone Figgins could not field Daniel Nava's ground ball.
A base hit by Josh Reddick and a walk to Lars Anderson loaded the bases before Yamaico Navarro struck out to end the inning.
Ryan Rowland-Smith took over for Seattle in the seventh and was greeted by a leadoff single from Scutaro that was followed by Kalish's ground-rule double. Both runners scored when Martinez poked a double just inside the right-field line.
