DENVER (AP) - Jesus Montero and Justin Smoak hit back-to-back home runs, Blake Beavan tied a season-high with seven strikeouts and the Seattle Mariners held on to beat the Colorado Rockies 6-4 on Sunday to complete a three-game sweep.
Mike Carp also homered and Dustin Ackley had two hits for the Mariners.
Carlos Gonzalez homered among his three hits and Dexter Fowler also homered for Colorado, which has lost four straight overall and 8 of 10 at home in May.
Seattle was 8-4 on the road after sweeping a series in Detroit last month before losing 12 of their last 13 away from home.
Beavan (2-4) followed strong outings by Seattle's starters in the first two games with five-plus innings of two-run ball.
Colorado's Jeremy Guthrie (2-2) allowed three homers in a game for the fifth time in his career.
