Kawhi Leonard scored 36 points, Landry Shamet hit two clutch 3-pointers late and the Los Angeles Clippers beat the Dallas Mavericks 110-107 Tuesday night for their fourth straight win.
Dallas ended a four-game winning streak, and more importantly, lost a key piece in center Dwight Powell just as they welcomed back Kristaps Porzingis.
Porzingis scored 10 points on 4-for-17 shooting in his return after missing 10 games with right knee soreness. Late in the first quarter, Powell went down on a non-contact play with a right Achilles tendon injury.
Luka Doncic had 36 points, 10 rebounds and nine assists for Dallas. He scored 24 points in the second half to help rally the Mavericks after they trailed by double digits from late in the second quarter through most of the third.
A see-saw fourth quarter turned on Shamet's 3 from the left wing to give Los Angeles a 100-98 lead with 2:48 to play. Montrezl Harrell added two free throws, then Shamet sank another 3 from straight-on to put the Clippers up by seven. He finished with 18 points.
Maxi Kleber's dunk brought the Mavs within 108-105, but after a Clippers turnover, Tim Hardaway Jr.'s potential tying 3 spun around and out. JaMychal Green missed two free throws, but then Doncic missed two -- the second intentionally -- and Leonard sealed it with two free throws.
With Powell out, Dallas got 16 valuable minutes from former Clipper Boban Marjanovic, who had 12 points and seven rebounds. His turnaround hook with 6:23 to play tied it at 90, capping a rally from a 14-point, second-half deficit.

Powell went down with 2:57 left in the first quarter. He started to drive toward the basket but fell to the ground and immediately slapped the floor in pain. He was helped to the locker room putting no weight on his right leg.
The team later announced that Powell had an Achilles tendon injury and he was out for the game. Powell's teammate J.J. Barea -- who tore his right Achilles tendon last season -- was distraught as Powell was taken off the court.
Powell was averaging nearly 10 points a game in 39 games prior to the injury. With Porzingis out, Powell averaged 13 points over 10 games on 71% shooting.
