Dallas, TX (Sports Network) - Kevin Durant posted a career-high 52 points and hit the go-ahead shot with 16.5 seconds left in overtime to boost the Oklahoma City Thunder to a dramatic 117-114 win over the Dallas Mavericks.
Durant topped the 40-point mark for the third time in his last five games and made all 21 of his foul shots, but his best was saved for last against the team the Thunder swept in the first round of the playoffs in 2012.
Dirk Nowitzki, who had 18 points on 5-of-19 shooting for the Mavericks, made 1-of-2 foul shots with 41.8 seconds left to tie the game at 114.
Durant then drove to the foul line and lifted a shot over Shawn Marion to give the Thunder the lead.
A 3-point shot from Mike James caromed off the front of the rim, and Russell Westbrook sank 1-of-2 free throws with 2.7 seconds to go.
Oklahoma City, which gained its sixth straight win and moved to an NBA-best 32-8, held on when Vince Carter's 3-point try from the right corner came up short.
Westbrook ended with 31 points, while the Mavericks were paced by Carter's season-bet 29 points in a reserve role. Dallas had a four-game winning streak broken and fell to 1-8 in overtime this season.
