BOSTON – Bernie Williams’ glove wasn’t the only piece of equipment that hurt the Yankees yesterday at Fenway Park.

Williams’ bat didn’t produce a hit in four at-bats in a 7-6 loss to the Red Sox. It was Williams’ inability to make a catch in the eighth that helped the Red Sox score four runs.

Since going a combined 5-for-8 in games Tuesday and Wednesday, Williams is hitless in 10 at-bats, his average is at an unacceptable .214, he’s gone 42 at-bats without a homer, and he has only one RBI.

“You can’t assume it’s going to come – you have to keep working,” Williams said.

Along with calf and hamstring problems, Williams went through troubles with both shoulders in Florida. While he admits they aren’t 100 percent, he isn’t using them as alibis.

Alfonso Soriano wasn’t in the starting lineup because of a cramp in his left hamstring that he said wasn’t serious. He proved that in the ninth inning when he was nabbed trying to steal second for the final out of the game with Robin Ventura up.

As for his leg, Soriano said he would play today.

Pedro Martinez hit Giambi in the first and third innings. So when David Wells threw a pitch behind Trot Nixon’s head in the third, plate umpire Fieldin Culbreth warned both benches. That brought Torre out of the dugout.

“I made mention that we had Giambi hit twice. I just wanted to go on the record to make sure he was not going to keep Boomer from pitching inside,” Torre said.

Giambi, who got hit in the left elbow and left rib cage didn’t think Martinez was throwing at him.

“You dig in and they pitch inside,” Giambi said.
