Rookie James Harden scored six of his 11 points in overtime, helping the Oklahoma City Thunder salvage a 30-point outing by Kevin Durant and win their preseason home opener by beating the Phoenix Suns 110-105 on Monday night.

Amare Stoudemire scored 20 points for the Suns, who twice rallied from double-digit deficits _ the second time with backups _ and never led until overtime. Phoenix was up 103-100 before the Thunder closed the game on a 10-2 run. D.J. White put Oklahoma City ahead for good at 104-103 with a jumper with 2:55 left and Michael Harris followed with a three-point play.

Durant went 5 of 5 from 3-point range as the Thunder finished 9 of 17 from behind the arc.

Jeff Green scored 15 points and Russell Westbrook just missed a triple-double with 10 points, 10 rebounds and nine assists for Oklahoma City.

Phoenix rallied from a 16-point first-quarter deficit to tie the game early in the third quarter and missed a chance to go ahead when Stoudemire muffed a dunk. Green hit two 3-pointers to put Oklahoma City back ahead.

Thanks to Durant's 19 third-quarter points, the Thunder built its lead to 90-73 by the end of the quarter and was up 97-77 with 8:16 left. But Oklahoma City managed only one more basket and didn't score in the final 3:38 of regulation.

With both teams using mostly subs, Phoenix tied the game at 99 on a driving layup by Carlos Powell with 30.6 seconds left. Phoenix's Earl Clark, then Oklahoma City's Shaun Livingston both missed shots in the final seconds of regulation.

Thabo Sefolosha scored 12 points on 5 of 6 shooting in his preseason debut for Oklahoma City. Sefolosha sustained a mild concussion during a practice on Oct. 5 and didn't play in the Thunder's first two preseason games, road losses to Memphis and New Orleans.

He started quickly Monday, scoring two baskets and assisting on another as Oklahoma City scored the first 11 points. His 3-pointer seven minutes into the game gave the Thunder a 22-6 lead.

Phoenix didn't score until Stoudemire's basket more than four minutes into the game and the Suns missed eight of their first nine shots.

The Suns spent the rest of the half playing catch-up, twice closing within five points. Oklahoma City led 53-47 at halftime. Stoudemire scored the first six points of the second half to tie the game before missing the dunk.

Phoenix fell to 1-2 in exhibitions, having beaten Partizan Belgrade and lost to Golden State. The Suns played without center Robin Lopez, who is out for six to eight weeks after breaking the fifth metatarsal in his left foot during an intrasquad scrimmage.

Jared Dudley was the only other double-digit scorer for Phoenix, finishing with 12 points. Steve Nash had nine points and seven assists in a little more than 25 minutes but joined most of the Suns' regulars on the bench in the fourth quarter and overtime.
