SEATTLE (AP) – Bronson Arroyo pitched seven shutout innings, and Manny Ramirez and Mark Bellhorn homered, leading the Boston Red Sox to an 9-0 victory over the Seattle Mariners on Saturday night.

With pro-Boston fans in the Safeco Field crowd of 44,401 chanting “Let’s Go Red Sox!” Boston stayed 21/2 games back of the New York Yankees in the AL East with their 28th win in 34 games. The Yankees beat Baltimore 5-2 earlier.

Arroyo (9-9) won his fourth straight decision, allowing four hits, no walks and six strikeouts. He came out with a 7-0 lead after making 85 pitches.

Mike Timlin and Alan Embree finished up the five-hitter, Boston’s 12th shutout of the season. The Mariners were shut out for the 11th time.

Seattle’s Ichiro Suzuki, who leads the majors with 229 hits, went 0-for-4 for the second straight night to drop his batting average to .373. He has 21 games left to tie the single-season major league record of 257 set by George Sisler in 1920 for the St. Louis Browns.

Ramirez got the Red Sox off to a quick start in the first inning when he hit his AL-leading 41st homer – and third in two games – on a 1-2 pitch from Jamie Moyer (6-11), a 429-foot shot to center.

Ramirez’s nine homers against Moyer is the most he has hit against any major league pitcher.

Bellhorn tagged his 16th homer of the season, a two-run shot, to cap Boston’s four-run fifth. His homer also came off Moyer, who has allowed a major league-leading 41 home runs, tying Robin Roberts (1955), Phil Niekro (1979) and Rick Helling (1999) for sixth place on the all-time homers allowed list. Bert Blyleven (1986) holds the major league mark with 50.

In the second, Boston increased its lead to 3-0 on Kevin Millar’s RBI double and Gabe Kapler’s run-scoring single.

In the fifth, Johnny Damon had a two-run double for the Red Sox before Bellhorn’s homer.

Moyer lost his career-high ninth consecutive decision and hasn’t won since June 18. Since then, he’s made 16 appearances – 15 starts -and has seen his ERA go to 5.09 from 3.64.

Moyer, 41, was an All-Star and a 21-game winner last season.
