Trailing by 10 in the fourth quarter, the Dallas Mavericks clamped down on the host Memphis Grizzlies in the final minutes Wednesday night and won, 81-80, for their 10th straight victory.
It was the 10th straight game an opponent has failed to reach the century mark against Dallas, a franchise record.
''We've been relying on the defense a lot more," said Jason Terry, who had 9 of his 15 points in the fourth-quarter comeback. ''That's starting to be the new motto for our team, starting to be our reputation now. Defensively, during this stretch that we've been playing well, we've been pretty much putting the lockdown on teams."
Dirk Nowitzki made two free throws with 7.2 seconds left, his only points of the fourth quarter, for the winning margin.
Mike Miller's drive with 3 seconds left bounced off the side rim, sending Memphis to its third loss in four games.
Ray Allen scored 32 points and Rashard Lewis added 26, leading the host Seattle SuperSonics to a 111-107 comeback victory over the Golden State Warriors.
The Warriors shot only 2 for 21 in the third quarter -- getting baskets by Derek Fisher and Baron Davis -- and Golden State had a season-low 9 points in the period to fall behind, 85-71. The Sonics had runs of 12-0 and 10-0 in the quarter.
Allen put the Sonics ahead to stay at 64-63 with a driving layup with 4:11 gone in the second half. The Sonics led by as many as 15 in the third period. Davis led the Warriors with a season-high 35 points.
Tim Duncan had 14 points and 17 rebounds, and the San Antonio Spurs won their fifth straight by beating the Trail Blazers, 86-82, in Portland.
Manu Ginobili had 22 points and Tony Parker added 20 for the Spurs, who have won nine of their last 10 games.
Zach Randolph led Portland with 25 points -- 19 in the second half -- and nine rebounds.
