Kevin Durant scored 40 points, Russell Westbrook added 22 points and 11 assists, and the Oklahoma City Thunder avenged a loss at Memphis earlier this week by beating the Grizzlies 109-100 on Saturday night.

Durant eclipsed 40 points for the second time in two weeks, hitting a pair of free throws and then a jumper from the left elbow after Memphis had pulled within two in the final 2 minutes.

The Thunder then put it away from the foul line, ending Memphis' bid to win four straight games for only the second time this season.

Zach Randolph had 27 points and 16 rebounds — including nine on the offensive end — and Rudy Gay scored 20 for the Grizzlies. Memphis beat Oklahoma City 110-105 on Tuesday night in Tennessee.

The Grizzlies trailed almost the entire night but got within two points on five separate occasions in the final 6 minutes. Yet Memphis never got the chance to take a shot to forge a tie or take the lead, as Oklahoma City answered each time.

Durant, who was the Western Conference player of the month in December, kept up his hot stretch but fell just shy of his season-best 44 points that came Christmas night against Denver.

He went 13 for 24 from the field and added 13 free throws, eight rebounds and four assists. Jeff Green had 15 points and Oklahoma City outrebounded the Grizzlies 47-40 despite being outscored 60-38 in the paint.

After Oklahoma City had let a 12-point lead slip away, Durant led the way as the Thunder restored their lead with a 14-4 run late in the third quarter. Durant dunked with two hands, hit a fadeaway jumper and then made a 3-pointer from the left wing before Westbrook's two free throws made it 81-71.

Memphis stayed right in the thick of it with O.J. Mayo's dunk and Sam Young's reverse layup at the end of the third, and Darrell Arthur's jumper to begin the fourth quarter cut the deficit to four.

Serge Ibaka had a two-handed putback dunk to start an 11-2 run that finished with James Harden hitting three free throws to extend Oklahoma City's lead to 39-27 with 8:36 left in the first half.

Greivis Vasquez converted a three-point play to start a 7-0 response by the Grizzlies, and Memphis was back within 49-47 by halftime. Randolph put back offensive rebounds on consecutive possessions to give the Grizzlies their first lead at 57-55 early in the third quarter.

NOTES: Memphis rookie and Oklahoma City native Xavier Henry missed his seventh straight game with a sore right knee. ... A new NBA commercial shows Durant sitting with high-school teammates, who included the Grizzlies' Vasquez. In it, a man tells Durant he'll someday play for the Oklahoma City Thunder (who didn't exist at the time). "It's footage of me from high school, but that guy wasn't there," Durant said. "He wasn't there that day. I had a dream about something like that. It wasn't that exact thing, but I had a dream about something like that and it was cool that they brought that to life."
