Mavericks 117, Kings 116 (2 OT)
DALLAS -- Point guard Deron Williams nearly gave the Dallas Mavericks a victory at the end of regulation Tuesday night.
Instead, he did at the end of the second overtime.
Williams' 3-pointer from the corner at the buzzer finished off an 8-0 run that lifted the Mavs past the Sacramento Kings 117-116 in double overtime at American Airlines Center.
The Mavericks (20-15) snapped a two-game losing streak and beat the Kings for the 22nd consecutive time in Dallas.
Sacramento (14-21) had won its two previous games, including the franchise's first-ever victory in Oklahoma City on Monday night.
The Kings were in position to pull off another stunner when they led 116-109 with 1:20 left in the second OT.
Power forward Dirk Nowitzki's 3-pointer pulled Dallas within two points with 26 seconds left. The Kings were unable to get a shot off, setting up a final possession for the Mavs with 2.3 seconds left.
Williams (25 points) took a sideline inbounds pass in the corner and used one pump fake before draining the game-winner at the buzzer. He also hit a finger roll with 2.1 seconds left in regulation that gave Dallas a 98-96 edge.
The Kings were carried by center DeMarcus Cousins, who scored Sacramento's first nine points in the second extra session and finished with 35 points and 17 rebounds.
Cousins, who added six steals and four assists, sent the game into the first overtime with a driving layup.
Kings small forward Rudy Gay scored 31 on 13-of-20 shooting. His 3-pointer gave Sacramento a 116-109 lead late in the second OT.
Nowitzki scored 23 and shooting guard Wesley Matthews had 20 points. Reserve center JaVale McGee had first double-double in nearly three years with 13 points and 11 rebounds.
Dallas fans were anticipating the return of point guard Rajon Rondo, but the league's assist leader was out with a bad back. The back began giving him problems against Oklahoma City and worsened Tuesday morning.
Rondo and the Mavs were a bad fit last season after an early-season trade from Boston, and he left the team during the first round of the playoffs.
Mavs small forward Chandler Parsons exited the game with a right hip injury.
The Mavericks finish off a back-to-back Wednesday night at New Orleans. Sacramento returns home Thursday to play host to the Los Angeles Lakers.
