BOSTON (AP) -Rudy Gay scored 28 points to lead Memphis to a 111-91 victory over the Boston Celtics on Wednesday night and give the Grizzlies a franchise-record seventh straight road win.
It was the Grizzlies' first victory over Boston in seven tries since 2006.
O.J. Mayo scored 17 points and Zach Randolph had 13 points and 10 rebounds for Memphis.
Ray Allen and Rajon Rondo scored 17 points apiece, and Rondo added eight assists for the Celtics. It tied Boston's worst loss of the season - a 20-point loss to Cleveland last month that was the worst loss for the Celtics with Kevin Garnett in the lineup.
The Celtics lost in Milwaukee on Tuesday night to snap a four-game winning streak.
Memphis led by 15 after the first quarter, by 22 at the half and by 19 after three. The Grizzlies led by as many as 29 in the fourth quarter, when Garnett never got off the bench.
Celtics fans weren't about to sit still, though.
Having booed the team off the court at halftime, they emptied the TD Garden during a timeout midway through the fourth quarter. The 20-point defeat matched the worst with Garnett. They had a 31-point loss, also to Cleveland, in a game that Garnett missed last April with a knee injury.
Allen, who was 0 for 3 on Tuesday night, scored a team-high six points in the first quarter against Memphis - the only Celtic to make more than one basket in the period.
Memphis scored the last eight points of the quarter to take a 27-12 lead - a season low in points for Boston in the first quarter. The Grizzlies scored nine of the last 11 in the second quarter to make it 55-33; the 33 points also were a season low for a first half for Boston.
Fans booed lustily as the Celtics left the court at halftime. And many of them just filed out quietly during a timeout with 5:41 to play, with the Celtics losing 102-77 and both teams emptying their benches.
NOTES: Each Celtic had a signed boxing glove from Manny Pacquiao in his locker before the game. ``Pacquiao is a huge Celtics fan,'' Boston coach Doc Rivers said. ``He tried to get in our locker room before our game in Los Angeles.'' ... Brian Scalabrine was inactive for matchup reasons, Rivers said. ... Randolph returned to the floor after missing Memphis' previous game with tightness in his lower back. ... Michael Finley made his first appearance in Boston with the Celtics, scoring 10 in 14 minutes.
