ATLANTA — Kevin Durant scored 29 points despite a sore ankle and Russell Westbrook hit a clinching 3-pointer, leading the Oklahoma City Thunder to a 111-104 victory over the Atlanta Hawks on Friday night.

Durant sprained his left ankle two nights earlier and wasn't cleared to play until an hour before the game, but the NBA's leading scorer turned in his usual performance. He came in averaging 28.4 points a game.

Westbrook hit the biggest shot of all. After Marvin Williams' putback pulled the Hawks within 102-100, the man wearing zero took a pass from Durant, picked up a screen from Nick Collison and swished a wide-open jumper from behind the arc.

As he headed back down the court, Westbrook blew on both hands as though they were six-shooters and mimicked sticking them in his holster. He finished with 28 points.

Joe Johnson led the Hawks with 24 and Kirk Hinrich added 21.

Durant wasn't expected to play after twisting his left ankle against Indiana. But he was able to take part in the morning shootaround, came out to do some additional shooting just before the game and declared himself ready to go.

He sure was.

Durant torched the Hawks for 12 points in the first quarter, then hit consecutive 3-pointers late in the second to complete an 18-point half that lifted the Thunder to a 56-51 lead heading to the break.

Atlanta was coming off its biggest comeback win of the season, having wiped out a 19-point deficit to beat the Chicago Bulls. The Hawks fell behind 14-0 in that one, so they made a point to get off to a fast start against Oklahoma City.

Hinrich came out flying, hitting a 20-foot jumper right off the tip, then swishing a long 3 that gave the Hawks an 11-4 lead less than 3 minutes into the game.

But Durant went to work, evening the score at 16 with a fadeaway jumper, and James Harden scored on a burst to the basket with the clock winding down to put the Thunder up 31-26 at the end of the quarter.

The Hawks trailed by as many as 13 in the final quarter before making a late run. When Williams grabbed the rebound off Hinrich's miss, banking it in to cut the deficit to a mere basket, the crowd of nearly 18,000 was on its feet imploring Atlanta to make one more defensive stop.

It didn't happen. Westbrook, who had jawed earlier in the quarter with Hinrich, finished off the Hawks by knocking down his only 3-pointer of the night with 1:11 remaining.

The Hawks played their second game in a row without forward Josh Smith, sidelined by a sprained right knee. He cheered on his team from the bench, wearing a suit and tie.

Smith's absence forced the Hawks to go deeper into their bench than normal. Etan Thomas made his first appearance since Jan. 22.
