Boston ? The Boston Red Sox were enjoying a record-breaking performance when a hush fell over Fenway Park.

Boston set a major league record by scoring 10 runs before making an out, scored 14 runs in the first inning and cruised to a 25-8 victory over Florida Friday night — but it was marred by a frightening injury to Marlins pitcher Kevin Olsen.

Todd Walker’s seventh-inning line drive hit Olsen in the head and 34,764 fans fell silent. He was carted off the field on a stretcher and taken to the hospital, where he was in good condition with minor injuries.

“After I hit the pitcher, I was concerned about him,” Walker said. “I couldn’t think of much else.”

The benches emptied after Boston reliever Hector Almonte was ejected for throwing behind a batter. And Marlins manager Jack McKeon accused the Red Sox of running up the score in one of their greatest offensive performances ever.

“I didn’t realize your pitching was that bad over here at Boston that you would try to add on a 16-run lead in the seventh inning,” he said.

He was upset that with the score 21-5, Walker tagged up from third on a short fly to center fielder Juan Pierre. Walker was thrown out, ending the inning, but Boston had two more sacrifice flies in the eighth.

McKeon didn’t blame Boston manager Grady Little, but Little understood the complaint.

“A couple of those balls went to the wall,” justifying a runner tagging up, he said, “but the one shallow fly ball that went to center field … I might even question that.”

Boston's Manny Ramirez, right, accepts congratulations from teammate Nomar Garciaparra (5) after belting a first-inning, three-run homer. The Red Sox scored 10 runs before making an out and hammered Florida, 25-8, Friday night in Boston.

That late offense contributed to Boston tying a team record with 28 hits and scoring the second most runs in team history. The records for runs and hits both came in a 29-4 win over the St. Louis Browns on June 8, 1950.

According to the Elias Sports Bureau, baseball’s statistician, the previous record for runs scored before making an out was nine, set by the Philadelphia Phillies on Aug. 13, 1948, against the New York Giants.

The Red Sox equaled the AL mark for runs in the first inning with 14, one shy of the major league mark set by the Brooklyn Dodgers in 1952, and raised their batting average from .294 to .297 in that inning alone.

But Fenway Park was quiet after Walker’s line drive hit Olsen on or just behind the right ear.

Olsen lay on the mound for nine minutes and moved his feet and blinked before being carried from the field on a stretcher. He was taken to Beth Israel Deaconess Hospital, a few blocks from the ballpark.

Olsen’s injury was considered minor.

For Boston, Bill Mueller had a career-high six RBIs, Jason Varitek had four and Johnny Damon, Manny Ramirez, David Ortiz and Walker three each.

Damon equaled a major league mark with three hits in an inning — a single, double and triple in the first.

“I had one of my worst batting practices of the year today,” Damon said.

White Sox 4, Cubs 3

Chicago — Jose Valentin hit a one-out homer in the bottom of the ninth as the White Sox beat the crosstown Cubs. Valentin sent a pitch from Antonio Alfonseca (0-1) well over the fence in right center for his 11th homer of the season, raising his arms in triumph and sprinting happily around the bases before he was mobbed at the plate.

The White Sox, winners of five of their last seven overall, have also captured three of the first four meetings with the Cubs in their spirited interleague series.

The Cubs, who have lost three straight overall, tying their season’s longest skid, scored two in the top of the ninth to tie the game on a bases-loaded sacrifice fly by Sammy Sosa and an RBI single by Moises Alou off Billy Koch (3-4).

Yankees 6 Mets 4

New York — Hideki Matsui and Jason Giambi hit early two-run doubles and David Wells hung on, leading the Yankees past the Mets. A crowd of 55,226 at Yankee Stadium saw the Yankees improve to 3-0 against the Mets in interleague play this season. The teams will meet in a two-park doubleheader today, starting in the Bronx by day and moving to Shea Stadium at night. Wells (10-2) won despite allowing 12 hits — one shy of his career high — in six innings.

Brewers 13, Twins 1

Minneapolis — Matt Kinney allowed eight hits in his first career complete game, and Richie Sexson had three hits and five RBIs to power Milwaukee past Minnesot. Sexson, John Vander Wal, Brooks Kieschnick and Eddie Perez each homered and Scott Podsednik had a career-high three hits for the second straight game for the Brewers.

Indians 3, Reds 0

Cleveland — Rookie Billy Traber pitched seven sharp innings for his first win as a starter and Cleveland snapped a three-game losing streak. Traber (3-4) allowed five hits in his longest career outing. The left-hander, who moved into the starting rotation in May when Jason Bere was lost for the season, walked one and struck out five.

Blue Jays 6, Expos 5

Toronto — Montreal reliever Julio Manon walked Toronto’s Shannon Stewart with the bases loaded in the bottom of the ninth inning. Toronto ace Roy Halladay failed to win his 12th straight start, allowing five runs on nine hits in eight innings for a no-decision.

D’backs 8, Tigers 3

Detroit — Arizona tied a franchise record with its ninth straight win. Chad Moeller scored on a wild pitch to break a 3-3 tie in the seventh, then added an RBI single in the eighth for the Diamondbacks, who have had three other nine-game winning streaks, the most recent from August 10-19, 2001.

Mariners 8, Padres 2

Seattle — Joel Pineiro pitched four-hit ball into the eighth inning and Carlos Guillen homered as Seattle beat San Diego. Pineiro (8-5) won his third straight start and improved to 4-1 over his last six with one of his best efforts of the season.

Phillies 4, Orioles 2 (17)

Baltimore — Jason Michaels hit a three-run homer in the 17th inning to carry Philadelphia past Baltimore in a marathon that featured poor clutch hitting and lasted 5 hours, 41 minutes. It was the Orioles’ longest game in innings since September 1974, when Baltimore needed 17 innings to beat Milwaukee 1-0.

Giants 6, Athletics 0

San Francisco — Jerome Williams pitched a seven-hitter for his first major league shutout, and Barry Bonds hit his 634th career homer as San Francisco beat Oakland. Pedro Feliz had a homer and a two-run single, and Jose Cruz Jr. also homered as the Giants evened the Bay Bridge Series at two games apiece. Oakland won two of three at the Coliseum last weekend. Bonds led off the sixth inning with his 21st homer of the season, putting Ted Lilly’s pitch into McCovey Cove beyond the right-field arcade.

Angels 3, Dodgers 0

Anaheim, Calif. — John Lackey pitched into the eighth inning, and David Eckstein’s RBI triple snapped a scoreless tie in the seventh as Anaheim beat Kevin Brown and Los Angeles. Lackey (5-7), who has struggled much of this year, outpitched Brown as the Angels beat the Dodgers’ ace for the second time in six days. Los Angeles took two of three in the first round of the Freeway Series last weekend.

Braves 8, Devil Rays 2

St. Petersburg, Fla. — Horacio Ramirez won his sixth straight decision and Chipper Jones went 4-for-5 with a two-run homer as Atlanta beat Tampa Bay. Gary Sheffield and Andruw Jones also homered to give manager Bobby Cox his 1,500th victory with Atlanta. Rafael Furcal hit a three-run double for the NL East-leading Braves (50-27), the first NL team this year to reach 50 wins.

Rangers 10, Astros 7

Houston — Rafael Palmeiro hit his 508th career homer, a three-run shot that led Texas past Houston. Before the game, Texas slugger Juan Gonzalez rejected a trade to the Montreal Expos, exercising a no-trade clause in his contract three days after the teams agreed to a deal. Gonzalez walked as a pinch-hitter in the ninth.
