DALLAS -- After hitting the buzzer beater in overtime, the Warriors' Stephen Curry smiled at Dallas and gestured to the crowd as he repeated the line, "We out."
Curry used his go-to move, hitting a step-back jump shot with one-tenth of a second left in the extra period as the Warriors escaped Dallas with a 122-120 overtime win with their position in the standings much more secure.
Curry regained his balance to shoot over Dallas' Jose Calderon for a win that couldn't have come at a better time for the Warriors. With eight regular season games left, they pushed their lead above the Western Conference's No. 7 and No. 8 teams Memphis and Phoenix to two games. The Warriors also won the season series against Dallas to earn the tiebreaker for a team they lead by 21/2 games in the standings.
"You enjoy the moment," Curry said. "The atmosphere was crazy."
Coach Mark Jackson celebrated his 49th birthday with a big road win with the team's front office in attendance and said Curry's shot looked good all the way.
"I almost started moon-walking," he said.
The Warriors, who leave for San Antonio to face an opponent Wednesday riding an 18-game winning streak, got 23 points and 10 assists from Curry and contributions across the board as they came through in the final minute of overtime.
Jermaine O'Neal, taking over the lineup spot for an injured Andrew Bogut, tied the score at 120 with a dunk with 28.5 seconds left before blocking Monta Ellis on the other end to set up Curry's game-winner.
The 18-year veteran finished with 20 points and eight rebounds in 33 minutes while Draymond Green had nine points, seven rebounds and a career-high six assists starting in place of an injured David Lee.
Klay Thompson led the Warriors with 27 points and tied the score at 108 with a 3-pointer with 1:01 left in regulation. But neither team would score until overtime as Marreese Speights had a dunk blocked and Curry missed a 3-pointer in the Warriors' final possession before the extra period.
"We never hang our heads," Thompson said. "We might have done that last year, but this is a changed team."
Dirk Nowitzki led all scorers with 33 points and had 11 rebounds while Ellis added 27 points. Dallas led 62-53 at halftime and took control of the game with a 41-point second quarter, marking the most number of points the Warriors have given up in any quarter this season. The Mavericks saw Vince Carter hit back-to-back 3-pointers and Nowitzki do the same while scoring 11 straight points for Dallas.
But when the Mavericks made their runs, the Warriors had answers. Jordan Crawford added 19 off the bench, going 7 for 10 from the field to give his team offense when it needed him most.
At halftime, neither Curry nor Thompson had made a single 3-pointer, as they each missed three attempts from beyond the arc. They combined for seven made 3-pointers in the second half.
The Warriors have now won 16 of their past 21 road games, excelling away from Oracle Arena and seeing this win coming two days after a home setback against New York.
This time with neither Bogut (pelvic/groin contusion) nor Lee (right hamstring strain) available to play, the Warriors fared better. Dallas did shoot 57.1 percent from the field and connect on 15 of 31 shots from 3-point range, but Golden State stopped the former Warrior Ellis in the end.
"For us to be holding the fort down without Bogs or DLee, without losing any ground, this is huge for us to try to capitalize," Curry said.
Curry, who passed up the shot and committed a turnover in the final sequence against New York, did his part at Dallas.
"He's become a real good closer," Thompson said. "I've got to guard him in practice, so I know what it's like when he hits those kinds of shots."
