SEATTLE -- Seattle's bats woke up in New York, and the Mariners brought their power display back home Friday night.
Adrian Beltre's three-run homer, a 440-foot shot off the top of the
out-of-town scoreboard in left-center field, highlighted a three-homer
night for Seattle, and the
Beltre had two hits and a season-high four RBI. Randy Winn added three hits, including a three-run double in the fifth that gave Seattle a 12-6 lead. Ichiro Suzuki had three hits, including an RBI triple.
Richie Sexson and Raul Ibanez added solo home runs for Seattle in the third inning, the first time the Mariners have hit consecutive homers this season.
Seattle, which hit four homers in Wednesday's 13-9 loss to the Yankees, tied a season high with 15 hits.
The loss cost the Red Sox a chance to move into a first-place tie in the AL East with Baltimore, and was just their third loss in the last 13 games.
Julio Mateo (1-0) picked up the win in relief of starter Joel Pineiro, who didn't get out of the fourth after giving up six runs and eight hits.
Mateo worked 3 1/3 scoreless innings, allowing just two hits. He has allowed just one earned run in 22 innings this season.
Pineiro hasn't defeated the Red Sox since August 2002, and is 2-5 all-time against Boston.
Beltre's homer came in the fourth, after Seattle let 3-0 and 5-4 leads slip away. With one out, Suzuki and Winn each singled. Boston starter Jeremi Gonzalez (1-1) was pulled, and left-hander John Halama entered.
Beltre, hitting just .188 against lefties, jumped on Halama's first pitch for his fourth homer of the season. Seattle scored four times in the fifth off Halama, highlighted by Winn's one-out double to right-center.
Halama, who pitched for the Mariners from 1999-02, allowed five runs and four hits in 1 2/3 innings.
Mark Bellhorn homered for Boston during a four-run third. It was Bellhorn's first homer since last Sept. 15 -- a span of 156 at-bats. Further damage was avoided in the inning when Suzuki threw out Jason Varitek at the plate with two outs.
Johnny Damon singled in the third, extending his league-leading hitting streak to 18 games. Trot Nixon had a two-run homer in the fourth for Boston.
Sexson's homer gave him 10 for the season, surpassing his total from last year when he played in just 23 games before getting injured. He has five of Seattle's last 11 home runs.
Seattle won at home for the first time since beating Cleveland 9-1 on April 24 and is now 13-5 when hitting at least one homer.
Red Sox LHP David Wells threw a simulated game before Friday's game that included fielding. Both Wells and manager Terry Francona felt the session went well, but Francona would not put a timetable on Wells' return. "We need to see him bounce back. Tomorrow, we'll see how he feels." Wells went on the DL April 26 with a sprained right foot. ... Seattle manager Mike Hargrove said there could be changes in the order of the Mariners' starting rotation, but no one in the rotation would be replaced. ... Sue Bird of the WNBA champion Seattle Storm threw out the first pitch. ... The roof at Safeco Field was closed in the fourth inning.
