PHOENIX (AP) -- When Kevin Durant takes over a game, it's quite a show.
This time, it was at the expense of Marcin Gortat and the rest of the Phoenix Suns.
Durant scored 27 of his 41 points in the second half -- 19 in the fourth quarter-- and the Oklahoma City Thunder became the NBA's first 30-game winner this season by beating the Suns 102-90 on Monday night.
Russell Westbrook added 36 for the Thunder, but it was Durant who took over late in his fourth 40-point game, falling one shy of the season-high 42 he scored two games earlier against the Los Angeles Lakers.
Durant sank an array of pull-up jumpers, added a couple of casual 3-pointers, made a handful of layups, then punctuated his night with a spectacular dunk over Gortat for a three-point play.
"I am just having a lot of fun out there," he said. "I got away with a carry on that (last) play, but I was able to free myself up. I saw the lane. Everyone knows he does a great job of contesting in the lane. I just tried to finish with some strength."
Durant and Westbrook accounted for 47 of Oklahoma City's 51 second-half points.
"We basically lost to Russell Westbrook and Kevin Durant," Gortat said. "These two guys were just outstanding. They played great. The pick-and-roll between these two guys is just ridiculous."
Durant said the two-player dominance in the second half "was just the natural flow of the game -- how they were playing us."
"We set nice screen and rolls and we thought we could find some good stuff in the pick and rolls," he said. "Russ got it going early and I just tried to play off of everybody, and my teammates just told me to go be aggressive and luckily my shots were falling."
Oklahoma City won its fourth straight, the last three on the road to improve their NBA-best record to 30-8. Durant scored 33 Sunday night in an 87-83 win at Portland.
Shannon Brown scored 21 for the Suns. Gortat had 19 points and 15 rebounds, but was the unfortunate would-be defender on Durant's spectacular dunk late in the game.
Kevin Martin was the only other Oklahoma City player in double figures with 12 points.
The Thunder were without Serge Ibaka for the second game in a row with a chest contusion. Phoenix didn't have Jared Dudley (right wrist strain) or Jermaine O'Neal (back spasms).
Down 68-54 after Westbrook's layup, the Suns finished the third quarter with a 14-4 run, cutting it to 72-68 on Michael Beasley's 3-pointer with 3.3 seconds left in the period. Oklahoma City didn't get a field goal in the final 5:23 of the quarter, its only points coming on Durant's four field goals.
But the Suns never got any closer.
Durant opened the fourth quarter with a fastbreak layup, sank a 19-footer, then followed with a 3-pointer and the Thunder led 79-72. Westbrook's 3-pointer put Oklahoma City up 87-77 with 4:49 to play, then Durant put on a final show.
He sank a 3-pointer, followed with a 19-footer, then scored on a layup. The spectacular finish came on Oklahoma City's next possession when he drove the lane and soared over Gortat for the dunk. Gortat fouled him on the play and Durant made the free throw to put the Thunder up 97-81 with 2:23 to play.
"I ain't going to deny it. That was probably one of the top three dunks of the year," Gortat said. "At least I'm going to be out there. I'm just going to try to be silly about it. I'm not going to cry. It's just part of the game. I already knew what was going on when he took off. I didn't lift my hands up. I just tried to get out of the picture and at least smile."
Oklahoma City used a 17-5 run to go up 45-35 on Martin's 3-pointer with 3:09 left in the first half.
The Suns went 4 minutes, 15 seconds without a point in the early stages of the Thunder outburst.
Brown scored on a drive to the basket and was fouled for a 3-point play with 1.8 seconds left to cut Oklahoma City's lead 51-45 at the break.
