New York ? Boston is halfway to a massacre of its own.

The Red Sox blew out the New York Yankees for the second straight day, hitting three more home runs and getting five shutout innings from Ramiro Mendoza in a 10-2 win Saturday that brought them within two games of the AL East leader.

“Everybody knows we swing the bat,” said David Ortiz, who homered twice for the second straight day. “We’re not afraid.”

Twenty-five years ago, the Yankees went to Fenway Park four games out in early September and swept four games by a combined score of 42-9, going on to win the division and the World Series.

Boston came to Yankee Stadium four games back Friday and has outscored New York, 20-5, in halving its deficit, hitting 10 homers off a staff that had allowed a league-low 70 in its first 83 games.

“They’re hot. They’ve been teeing off on a lot of people lately,” Derek Jeter said. “Usually with our pitching staff, you don’t see that.”

Roger Clemens fared no better than David Wells a day earlier, and it was Mendoza, not the six-time Cy Young Award winner, who defeated his former team.

Clemens (8-6) became the second straight Yankees starter to give up eight runs against the major leagues’ leading offense, which has a .298 team average. Eight of the nine batters in Boston’s starting lineup, all but leadoff man Johnny Damon, came in with batting averages of .300 or higher.

“It’s scary. It’s like a snowball effect,” Kevin Millar said. “It just keeps going and going and going.”

Boston broke on top in the second when Clemens hit Millar on the left hand with a pitch, and Trot Nixon homered on the very next delivery.

“That’s the best feeling there is,” Millar said.

Boston didn’t try to guess if Clemens was trying to back Millar off the plate.

“That’s something for him to answer himself,” Nixon said.

Clemens faulted Millar for getting hit.

“Guys don’t get out of the way of the ball anymore,” he said.

Ortiz had a solo shot in the fourth against Clemens and a two-run drive off Jason Anderson in the ninth. Before the series, Ortiz’s teammates were calling him “Juan Pierre,” a reference to the Florida outfielder who began Saturday with no homers in 363 at-bats.

In less than 24 hours, Ortiz raised his season home run total from five to nine and doubled his career multihomer games to four.

“Now they’re calling me ‘Furcal,'” he said, referring to Braves shortstop Rafael Furcal, who entered the day with 11 homers.

After the two early homers, the Red Sox broke open the game with a three-run fifth that included a two-run single by Damon, who had three RBIs.

Angels 6, Athletics 3

Oakland, Calif. — Tim Salmon homered twice, and Ramon Ortiz won for the sixth time in seven starts to lead Anaheim past Oakland. Salmon connected on a 2-0 pitch from Aaron Harang (1-3) for a three-run homer in the first inning, sending the ball deep into center field. Eric Byrnes jumped at the wall to try to make the catch, but had no chance. Salmon had homered only four times in his past 54 games and hit .215 in June.

Mariners 3, Rangers 2 (10)

Arlington, Texas — Dan Wilson’s RBI single with one out in the 10th inning lifted Seattle past Texas. Randy Winn greeted reliever Ugueth Urbina (0-4) with a single to open the 10th. Winn went to second on Jeff Cirillo’s sacrifice bunt and raced home on Wilson’s bloop single over the head of Rangers second baseman Michael Young. Juan Gonzalez hit a two-run homer, his 20th, and Kevin Mench went 3-for-4 for Texas.

Devil Rays 3, White Sox 2

St. Petersburg, Fla. — Javier Valentin hit a solo homer, and Jorge Sosa won for the first time since April as Tampa Bay beat Chicago for its first three-game winning streak under manager Lou Piniella.

Piniella pledged last month to dye his hair if his young team won three in a row at any point this season.

Lance Carter nearly blew a three-run lead in the ninth, allowing a solo homer to pinch-hitter Magglio Ordonez and a one-out RBI double to Frank Thomas.

Carter recovered to strike out Brian Daubach and retire Carl Everett on a flyout for his 14th save in 20 opportunities.

Valentin, the younger brother of White Sox shortstop Jose Valentin, snapped a scoreless tie with his fifth-inning homer off Esteban Loaiza (11-4).

Indians 13, Twins 2

Minneapolis — Casey Blake went 5-for-5 with two homers and seven RBIs against his former team, leading Cleveland past Minnesota. Matt Lawton — another former Twin — and Milton Bradley homered for the Indians, who received seven solid innings from starter Brian Anderson (6-6).

The left-hander won his third straight decision, allowing two runs and six hits, four for extra bases. He walked two and struck out four.

Matthew LeCroy and Corey Koskie hit solo homers for the Twins, who have lost 15 of 21 and again failed to build momentum from an emotional win — a 9-2 victory over Cleveland on Friday that featured a bench-clearing scuffle and five ejections.

Orioles 9, Blue Jays 2

Baltimore — Jeff Conine hit two homers and drove in five runs, and Sidney Ponson pitched eight strong innings to earn his 11th win as Baltimore breezed past Toronto. Brook Fordyce also homered, and AL batting leader Melvin Mora had four hits to help the Orioles extend their winning streak to four — tying a season high.
