Ibaka finished with 17 points, seven rebounds and three blocks. Durant was 10 for 16 from the floor, helping the Thunder outshoot the Warriors 50.6 to 44 percent.
Bogut exited with 2:55 remaining in the quarter, went to the locker and did not return. The team said Bogut sprained his left ankle, which he broke in January of 2012 and underwent microfracture on last April.
In the meantime, Durant and Westbrook got rolling late in the second half, including that incredible series that led to Durant's dunk and will surely fill the highlights.
"When I said killed them, I mean our attitude was straight focused, laser-focused, ready to play every possession, locked in on every possession at both ends," Durant said. "We knew what we were playing for. We know every game is important. So we were locked in from the beginning. That's what we need to do."
The Thunder's defense smothered Golden State's shooters in the third quarter to put the game away. They started the third quarter on a 22-5 run, and they took a 94-73 lead on Durant's 3-pointer in the final minute of the third quarter.
Oklahoma City played the second half without its center, too, due to an injury that seems far less serious. Kendrick Perkins sat out the final 24 minutes because of right hamstring tightness, but said he'll be fine.
With the Thunder in full control, there was no need to play anyway.
The only drama left was whether Durant would get his second triple-double of the season against the Warriors. Instead, Brooks replaced Durant with 8:14 remaining with his team still up 20 points.
Durant recorded his first career triple-double in a 119-109 win over the Warriors in Oklahoma City on Nov. 18.
"He's one of the greatest players in the game," said Warriors reserve Draymond Green, who got turned around when Durant threw down his dunk. "We have to be more physical."
NOTES: Martin left in the fourth quarter with lower back tightness but said he'll be fine. ... The Thunder won the season-series 3-1. ... Curry joined Ray Allen (2005-06), Dennis Scott (1995-96) and George McCloud (1995-96) as the only players in NBA history to make at least 250 3-pointers in a season.
