Brandon Jennings hit the go-ahead layup with 56 seconds remaining in overtime as the visiting Milwaukee Bucks ended their season Wednesday with a 110-106 win over the playoff-bound Oklahoma City Thunder.

Jennings had the final 10 points of the extra period to lift the Bucks (35-47) to the upset victory. He finished with 16 points while John Salmons added 15 and Ersan Ilyasova had 14.

Russell Westbrook poured in 20 points for the Thunder (55-27), who lost for just the second time in their last 15 home games. The loss guaranteed Oklahoma City a first-round matchup with their Northwest Division rival, the Denver Nuggets.

With the Thunder trailing by three points at halftime, Durant and Westbrook made the most of their limited second-half action, combining to score 12 points during an 18-5 run that spanned the middle of the third quarter. Durant kicked it off with a layup and Westbrook capped it with a thunderous dunk to put Oklahoma City up, 66-55.

The Bucks stormed back and drew within three in the final minute. Oklahoma City's Nazr Mohammed was called for offensive goaltending and Ilyasova evened the score on a 3-pointer with 23 seconds left.

Oklahoma City had a chance to win in regulation, but Mohammed missed a 15-footer at the buzzer.
