Boston ? With trade rumors about Manny Ramirez swirling around Fenway Park and the fans booing the outfielder every time he stepped to the plate, the Boston Red Sox proved once again they can win under duress.

John Olerud hit a grand slam, and Boston scored three runs after a single by Johnny Damon to beat the Minnesota Twins, 8-5, Friday night for their third straight victory.

Minnesota Gold Glove center fielder Torii Hunter sprained a tendon in his left ankle trying to scale the outfield wall in the first inning and had to be taken off the field on a stretcher. X-rays taken at Fenway Park showed no fracture, and Hunter will remain with the Twins through the weekend, then go Monday to Minnesota for an MRI. The injury could be a huge blow to Minnesota’s postseason hopes.

Twins manager Ron Gardenhire said Hunter would be placed on the 15-day disabled list and that Minnesota was unsure how long Hunter would be out.

“It was pretty scary. We know it’s not good, but we’ll hope for the best,” Gardenhire said.

Boston's Manny Ramirez, right, congratulates John Olerud for his eighth-inning grand slam against Minnesota. The Red Sox beat the Twins, 8-5, Friday in Boston.

Ramirez went 0-for-3 with a strikeout and a walk in his first game at Fenway Park since it was reported he asked Red Sox management to trade him. Following the game, David Ortiz, one of Ramirez’s closest friends on the team, expressed dismay at the fan’s treatment of the mercurial slugger and said he couldn’t picture the Red Sox without him.

“It’s a crazy situation, but I don’t think what our fans did today to Manny was fair, at all,” Ortiz said.

“His numbers are always there every year, and this town should never feel that way about Manny Ramirez,” Ortiz said. “If Manny’s out of here, it’s going to be hard on everybody. It’s as simple as that. … How are you going to replace a guy like that?”

Bronson Arroyo (9-6), the subject of persistent trade rumors during the past two weeks, held Minnesota scoreless for six innings before allowing Joe Mauer’s solo homer. He allowed three runs and five hits in 71â3 innings in one of his best outings of the season.

With the Red Sox leading 4-3 in the eighth, Olerud put the game out of reach with Boston’s club-record 10th grand slam of the season. The home run was the 250th of Olerud’s career.

Athletics 8, Tigers 4

Oakland, Calif. – Mark Ellis hit a two-run homer in a four-run second inning, and Oakland won for the ninth time in 10 games and improved to 12-3 since the All-Star break.

Rich Harden (9-4) allowed a career-high 12 hits and four runs while laboring through 51â3 innings. In the third, he allowed his first earned run at home in a stretch of 24 innings since May 13.

Six A’s drove in a run while building an early 7-1 lead against Sean Douglass (3-1), who couldn’t escape the third inning in his first loss since joining the Tigers last month.

Angels 4, Yankees 1

New York – Garret Anderson hit a two-run homer, and Bengie Molina added a solo shot in the second inning as Los Angeles ended a four-game losing streak.

Los Angeles was coming off an 18-inning loss in Toronto on Thursday night and didn’t arrive in New York until 4 a.m. Ervin Santana (6-4), who warmed up in the bullpen during the 18th against Toronto, won for the first time this season on the road, allowing six hits in 61â3 innings.

White Sox 7, Orioles 2

Baltimore – Chicago’s Paul Konerko and Carl Everett both homered and drove in three runs to back a strong pitching performance by Orlando Hernandez (8-3).

Konerko put the White Sox up 4-1 with a three-run drive off Erik Bedard (5-3) in the third, and Everett made it 6-2 with a two-run shot off Todd Williams in the seventh.

Rangers 4, Blue Jays 1

Toronto – John Wasdin and three relievers combined on a six-hitter as Chan Ho Park’s replacements for Texas. Park was scratched just before his scheduled start because the Rangers planned to trade him to the San Diego Padres for slugger Phil Nevin, a deal that awaited approval from the commissioner’s office.

Wasdin allowed one run and four hits in 42â3 innings. Doug Brocail (4-2) got the win, pitching 21â3 perfect innings.

Indians 10, Mariners 5

Seattle – Victor Martinez singled, doubled and hit a three-run homer in his first three at-bats to lead Cleveland’s 17-hit attack. Kevin Millwood (5-9) pitched into the seventh for the Indians before he was ejected for hitting Yuniesky Betancourt in the hip with his first pitch of the inning.

Seattle starter Aaron Sele (6-12) lost his seventh straight start.
