OKLAHOMA CITY — Russell Westbrook and Thabo Sefolosha made big baskets in the final 2 minutes Wednesday night, leading Oklahoma City to an 88-83 victory over the Washington Wizards for the Thunder's first three-game winning streak of the season.

Sefolosha made a reverse layup with 1:47 to play, pushing Oklahoma City's lead to 84-81. A jumper by Westbrook with 33.3 seconds remaining stretched the lead to five and Nenad Krstic added two free throws with 9.5 seconds left.

Krstic finished with 18 points, Sefolosha had 15 and Westbrook 12 with eight assists for the Thunder. Nick Collison added 12 points and 10 rebounds.

Antawn Jamison had 29 points and 10 rebounds for Washington, which failed to score in the final 2› minutes. Andray Blatche, starting in place of injured Caron Butler, and Darius Songaila scored 14 each.

The Thunder were without their top two scorers, Kevin Durant and Jeff Green, but Washington was short-handed as well, playing without Butler.

Sefolosha scored seven in a row, including a 3-pointer, to give the Thunder a 59-52 lead midway through the third quarter. Oklahoma City got a boost from Damien Wilkins later in the quarter when he made three baskets to stretch the lead to 67-58.

The Wizards cut the margin to five by the end of the period, then outscored Oklahoma City 14-4 in the first 5 minutes of the fourth quarter to take a four-point lead.

Jamison had 17 points in the first half when the Wizards opened as much as a seven-point advantage. Three straight baskets by Krstic and a shot by Westbrook brought the Thunder back before Jamison ended the run with a drive inside.

The Wizards consistently scored in close during the first half. They outscored the Thunder 30-24 on points in the paint and had a 14-2 edge in second-chance points. Songaila did a lot of that damage, scoring 10 first-half points.

Jamison had just one field goal in the third quarter when the Thunder went ahead by nine. Collison had six of his rebounds during the period.

Oklahoma City coach Scott Brooks again dipped deeper into his bench, with good results. Robert Swift, playing in his third straight game after missing 20 of the previous 21, contributed six points and three rebounds in 16 minutes. Wilkins also came off the benth and finished with eight points and seven rebounds.

Notes: Butler, averaging 20.3 points per game, missed his second straight game due to tightness in his left hamstring. ...
