SEATTLE -- Jon Lester's latest return to his home state didn't go as planned Monday night, and the Boston Red Sox matched their longest losing streak of the season as the Seattle Mariners cruised to an easy 11-4 victory.
Seattle jumped out to a 10-2 lead and piled up 15 hits while handing the Red Sox (54-37) their third consecutive loss.
The Mariners tagged Lester (8-5) for nine hits and five runs, doing most of their damage in the fourth, fifth and sixth innings. The native of nearby Tacoma labored through five-plus innings, eventually giving way to reliever Alex Wilson after allowing back-to-back singles to lead off the sixth.
Seattle's Raul Ibanez broke a 2-2 tie with a leadoff home run in the bottom of the fifth inning, his 22nd homer of the season and his eighth in the past 13 games, then added an RBI single with two outs in the sixth to give the Mariners a 6-2 lead.
Felix Hernandez (9-4) earned his first win since June 15, allowing six hits and two runs in seven innings of work.
Eight Mariners had hits in the game, led by Justin Smoak's 3-for-4 performance. Smoak had RBI doubles in the fourth and sixth innings, the latter of which gave Seattle a 7-2 lead while chasing Wilson from the game.
Seattle (40-49) won for the fifth time in its past seven games, and the Mariners have now hit a home run in 16 consecutive games. The 11 runs scored by Seattle were the most the Mariners had scored in a game since beating the New York Yankees 12-2 on May 15, when they had a season-high 16 hits.
The Red Sox have had four three-game losing streaks this season, but until Monday they had gone nearly eight weeks without dropping three in a row.
The Mariners scored twice in the fourth inning while sending eight batters to the plate.
Things could have been much worse for Boston, but a long fly ball from Nick Franklin with the bases loaded was caught on the warning track, leaving the Red Sox trailing at just 2-0.
NOTES: Red Sox LHP Andrew Miller, who was placed on the 15-day disabled list Sunday night, is scheduled to undergo season-ending surgery on his injured left foot, manager John Farrell said Monday. Miller has ligament damage in the foot. ... The Mariners designated RHP Jeremy Bonderman for assignment and called up LHP Lucas Luetge. Bonderman, 30, came back from 2010 Tommy John surgery but struggled in his past two starts, going 0-2 with a 10.80 ERA. The fill-in for Bonderman's scheduled Thursday start has not been determined -- Luetge is a reliever -- but Triple-A RHP Erasmo Ramirez seems a likely option. ... With singles in the second and fourth innings, Red Sox DH David Ortiz moved within four hits of tying the all-time record for career hits by a designated hitter. Harold Baines, with 1,688, holds the mark. ... Boston LF Mike Carp was a member of the Seattle organization until Feb. 20, when he was traded to the Red Sox for cash considerations. Carp told The Boston Herald on Sunday that he was eager to "do some damage against my old team."
