SEATTLE (AP) _ Bernie Williams had three hits, including one of New York's four home runs, to lead the Yankees to a fight-interrupted 11-8 victory over the Seattle Mariners on Friday night.

Trouble started in the bottom of the eighth inning when New York reliever Jason Grimsley hit Edgar Martinez with a pitch following Alex Rodriguez's three-run homer. Home plate umpire Gary Cederstrom promptly threw Grimsley out without a warning.

In the top of the ninth, Frankie Rodriguez entered the game and hit Chuck Knoblauch with a pitch in obvious retaliation. Seattle manager Lou Piniella immediately pulled Rodriguez, but the pitcher, angered at something on-deck hitter Joe Girardi said, went to the batters box and took two swings at Girardi, knocking him down.

Waves of Yankees charged the field, led by Shane Spencer, Girardi and Jim Leyritz, intent on getting to Rodriguez, who backpedalled to the Mariners dugout.

After the fight, Girardi was ejected.

Paul O'Neill, Scott Brosius and Knoblauch also homered for the Yankees, who beat the Mariners for the second straight night and for the fourth time in five games this season.

The four homers were the most for one team since Safeco Field opened July 15.

In Thursday night's game, a 7-4 win by the Yankees, All-Star shortstop Derek Jeter was hit by a pitch in the left wrist by Jose Paniagua. Jeter sat out Friday night's game.

New York manager Joe Torre was thrown out of his second game this season for arguing too strongly with first base umpire Doug Eddings. He was ejected in the bottom of the eighth on a close play at first after Raul Ibanez's fielder's choice groundout.

Jeff Fassero (4-13) lost his fifth decision in a row and surrendered all of the Yankees' homers, giving him a major league-leading 34 homers allowed this season.

Williams hit a 441-foot shot to center, the longest homer in 16 games at Safeco, in the first inning after O'Neill had a solo shot. Brosius followed with a three-run homer to give New York a 5-0 lead in the first.

Knoblauch had a two-run homer in the fourth to put the Yankees in front 7-3.

Williams went 3-for-4, including a two-run single in the fifth when New York scored four runs to go ahead 11-4. Williams' three RBIs gave him 11 in his last three games.

The Mariners, who lead the majors with 178 homers, have been outhomered 6-2 by New York in the first two games of the series.

Allen Watson (1-1), signed by the Yankees July 3 after being released by Seattle on June 28, got the victory in relief of Orlando Hernandez, who only got one out in the first. It was Hernandez's shortest stint in 44 career starts.

Watson pitched three innings and gave up one run on four hits and a walk.

The Mariners scored three runs off Hernandez in the first on Ken Griffey Jr.'s RBI single, Rodriguez's sacrifice fly and a bases-loaded walk to Ibanez.

Rodriguez had five RBIs for the Mariners, including his 27th homer. David Bell, Edgar Martinez and Griffey each had three hits for Seattle.

Mariano Rivera came in after Grimsley was ejected and got the final six outs for his 30th save in 34 opportunities. He also had a save Thursday night.

In 3 1-3 innings, Fassero allowed seven runs on 10 hits and a walk.
