(Reuters) - The Los Angeles Clippers rallied for a wild 101-99 victory over the Oklahoma City Thunder on Sunday to even their best-of-seven Western Conference semi-final at 2-2.

The Clippers overcame a 22-point hole in the first quarter and never led until the final minutes, yet found a way to avoid being pushed to the brink of playoff elimination.

Reserve Darren Collison sparked the Clippers with 12 of his 18 points in a wild fourth quarter, scoring four straight to put Los Angeles ahead 101-97 with 32 seconds left.

Thunder guard Russell Westbrook missed a potential game-winning three-pointer at the buzzer.

Kevin Durant had a game-high 40 points and added seven rebounds in the crushing defeat.

Blake Griffin tallied 25 points, while Chris Paul put up 23 and 10 assists for the Clippers' attack.

Game Five is Tuesday in Oklahoma City.
