NEW YORK (AP) -- The much-anticipated rematch between Pedro Martinez and Roger Clemens was decided by some lesser names.

Ramiro Mendoza pitched 5 2/3 innings in relief of an injured Clemens, and Tino Martinez hit a tiebreaking homer in the eighth inning after Pedro Martinez had left, giving the New York Yankees a 2-1 win over the Boston Red Sox on Wednesday.

That was just what the Yankees did after Clemens worked out of a bases-loaded, one-out jam in the first inning -- the only inning he'd pitch before leaving with a strained right groin.

Manager Joe Torre said the injury, which first flared up in Atlanta 11 days ago, may force the right-hander to go on the disabled list.

Mendoza, one of New York's heroes last October when the Yankees beat the Red Sox in the ALCS, came through by allowing one run in 5 2/3 innings and leaving with the score tied at 1. Jason Grimsley (3-1) got four outs and Mariano Rivera finished for his 15th save.

"All in all it could have been worse if we had lost the game," Clemens said. "But Mendoza and the 'pen did a great job and Tino came through with the big hit."

	Pedro Martinez pitched well, but once his pitch limit hit 100, he got the rest of the afternoon off.

"We want to protect this kid," manager Jimy Williams said. "We had wanted him to throw about 100 and he was there."

Martinez, who had gone at least seven innings in all 10 starts this season, walked two and struck out seven in his first no-decision since Sept. 15, 1999, at Cleveland.

"I just pitched the count," Martinez said. "I felt good enough to pitch another inning or more but they said I was over 100 and it was time to go. I never dispute their decision."

Mendoza, bumped in the rotation by Clemens after Monday's rainout, pitched out of trouble much of the game as Boston stranded 12 runners, but had only two hits in 16 at-bats with runners on base.

"We had chances with the right people," Williams said. "We hit some balls good that were caught."

With two outs in the seventh, the Red Sox finally tied the game on a controversial home run by Nomar Garciaparra.

Ricky Ledee nearly made a spectacular catch, leaping into the stands. The ball hit his glove, but the glove hit a fan, the ball popped out, hit the top of the wall and ricocheted in front of the foul pole into foul territory for what should have been a ground-rule double.

Ledee landed and looked at his glove in disbelief as third-base umpire Travis Katzenmeyer ruled the ball a home run, generating cheers from the Red Sox fans at Yankee Stadium. The Yankees didn't argue the call.
