His defensive presence inside was a major factor in the Cavaliers' 108-84 win, which pulled them within 2-1 in their Eastern Conference semifinal series.

Wallace helped hold Kevin Garnett to 17 points, blocked shots and drew offensive fouls as the frustrated Celtics never could overcome a 13-point first quarter.

Wallace finished with nine points _ a season playoff high _ along with nine rebounds and two assists.

An airball on a free throw attempt in the fourth quarter was his only ugly moment. A few seconds later he left the game to a standing ovation.

It appeared earlier in the day that Wallace wouldn't play. He missed the morning shootaround, and following the workout, coach Mike Brown said his best interior defender probably would sit.

However, Wallace had no problems while warming up, and about one hour before tipoff said he would try to play.

Wallace started Game 2 but played less than 4 minutes before leaving when he became dizzy. He had tests on Friday at the Cleveland Clinic.

Wallace said the symptoms have been tough to tolerate.

"It's like I'm in a wash cycle," he said. "My head starts spinning from time to time."

The Cavs described his ailment as a combination of allergies and an infection in his left ear.

The Celtics, who won the first two games of the best-of-seven series at home, lost their fourth straight road game of the postseason. Game 4 is Monday night in Cleveland.
