Pascal Siakam scored 33 points and grabbed 13 rebounds to lead the Toronto Raptors to a 123-114 overtime win against the host Oklahoma City Thunder on Wednesday night.
The Raptors dominated overtime, outscoring the Thunder, 13-4, after letting a big 19-point, second-half lead slip away.
Oklahoma City didn't score in the extra period until 31.5 seconds remained.
Kawhi Leonard scored five of his 22 points in overtime, and Fred VanVleet finished with 23 points for the Raptors.
Toronto was firmly in control for much of the game until a late push by the Thunder cut the lead to two on Paul George's 3-pointer with 40.9 seconds left.
George scored nine consecutive Oklahoma City points to put the Thunder back in the game, but he wasn't around for the end after picking up his sixth foul on the ensuing possession.
However, Oklahoma City forced a stop, and then Russell Westbrook gathered a head of steam and finished with a layup to tie the game with less than five seconds remaining.
The Thunder had the chance to win in regulation after Dennis Schroder drew a charge as Siakam attempted what would've been the game-winner.
Westbrook's 3-point attempt at the buzzer fell short to send the game to overtime.
Westbrook, returning from a one-game suspension and coming off a 2-for-16 shooting performance Saturday in a loss to the Golden State Warriors, helped lift the Thunder as George mostly struggled until his late push.
Westbrook finished with 42 points and 16-of-29 shooting, including 5-of-10 accuracy from behind the 3-point arc.
George finished with 19 points but was just 3 of 10 from behind the arc.
With the win and Milwaukee's loss to Cleveland earlier in the night, the Raptors are just two games behind the Bucks for the top spot in the Eastern Conference.
While the Raptors are surging, the Thunder's fade continued. Since the All-Star break, Oklahoma City is only 5-10, including defeats in each of the past four games.
Oklahoma City and the Raptors meet again Friday in Toronto.
Before the game, Nick Collison's number was retired by the Thunder, the first number retirement since the franchise moved to Oklahoma City.
Collison played all 14 seasons of his career with the franchise before retiring after last season.
