Russell Westbrook had 37 points and 10 rebounds, Kevin Durant scored 26 and the host Oklahoma City Thunder held off a second-half charge to beat the improving Los Angeles Lakers 122-105 on Tuesday night.
The Thunder led from start to finish but had its 18-point lead whittled down to five midway through the fourth quarter. Serge Ibaka, who dodged a suspension after delivering a low blow against Blake Griffin in Oklahoma City's previous game, hit a 3-pointer and Westbrook had a two-handed slam as the Thunder scored the last 12 points. Los Angeles didn't score for the last 6:14.
Kobe Bryant scored 30 points after leaving the game with a right elbow injury in the first quarter. Steve Nash matched his season best with 20 points as the Lakers fell back below .500 after reaching the mark for the first time since December.
Oklahoma City tied an NBA record with two turnovers.
Nuggets 120, Kings 113: Ty Lawson had 24 points and Danilo Gallinari added 23 as Denver won its sixth straight game, defeating host Sacramento. The Nuggets scored 70 second-half points when they shot nearly 64 percent.
The Denver interior defense helped make it a difficult evening for Kings leading scorer DeMarcus Cousins. He missed 11 of 12 shots, was 6 of 10 from the free-throw line and finished with eight points, 13 rebounds and a career-high five blocks.
Celtics 109, 76ers 101: Paul Pierce had 18 points and 11 rebounds, and Avery Bradley scored 22 points to lead Boston to a win in Philadelphia. The Sixers lost for the ninth time in 10 games. The Celtics are 12-4 since Rajon Rondo was lost for the season with a torn knee ligament.
Timberwolves: J.J. Barea's confrontation with Ray Allen got him ejected from Minnesota's game against Miami on Monday night. One day later, the NBA ruled that Barea never should have been ejected. The NBA downgraded a Flagrant-2 foul on Barea to a Flagrant-1 foul, meaning Barea will not face a fine or suspension for his foul on Allen.
Knicks: Carmelo Anthony might miss Wednesday night's game against Detroit with a stiff and sore right knee that has been bothering him for a couple of weeks. He left Monday's victory over Cleveland in the middle of the second quarter.
