Spurs 98, Nuggets 88
At Denver, Tim Duncan scored 25 points and Manu Ginobili added 20 off the bench in San Antonio's win over Denver.
With Ginobili still working his way back from a foot injury, the defending NBA champs now sport the league's best bench. Ginobili played 24 minutes and had his best performance since returning from an eight-game absence on Monday.
Reserve Robert Horry added 10 points, including critical 3-pointers that helped decide it in the third quarter. Michael Finley, who started for Ginobili, added 14 points.
Carmelo Anthony scored 25 points for the Nuggets, who have lost four of their last five at the Pepsi Center.
Grizzlies 100, SuperSonics 96
At Seattle, Dahntay Jones made a one-handed 4.3m shot with 6.6 seconds left, and Memphis held off Seattle.
Jones scored after Bobby Jackson appeared to travel. Jackson drove the lane and missed an underhanded layup badly. He grabbed the ball out of the air and passed to Jones, who leaned in and hit the shot to put Memphis ahead 98-94.
Officials said Jackson's shot had been partially blocked, but on television replays, the shot appeared to be untouched.
Rashard Lewis made two free throws with 3.3 left, but Jackson made a pair with 2.9 left for the final margin.
Pau Gasol led six Grizzlies in double figures with 22 points, eight rebounds and eight assists.
Ray Allen led Seattle with 28 points and Lewis added 19.
Celtics 111, Clippers 92
At Los Angeles, Ricky Davis scored 20 points, Paul Pierce added 19 and Boston downed the Los Angeles Clippers to snap a six-game road losing streak.
Cuttino Mobley scored 27 points and Sam Cassell had 24 for the Clippers, who lost for the seventh time in nine games. They have dropped 10 of their last 12 against Boston, including a double-overtime defeat last season at Staples Center.
The Celtics, who overcame a 20-point deficit to beat the Clippers the last time they faced each other last February in Boston, enjoyed a 20-point lead in the second quarter. Los Angeles rallied as both Cassell and Mobley had 12 points in the third quarter to pull the Clippers within 89-76.
Mobley's 3-pointer cut Boston's lead to 91-81 with 9 minutes to play, but the Clippers got no closer.
