DALLAS -- Kevin Durant scored a career-high 52 to lead the Oklahoma City Thunder to a hard-fought 117-114 overtime victory Friday night over the Dallas Mavericks at American Airlines Center.
Oklahoma City (32-8) won its sixth game in row in its first return trip to Dallas since beating the Mavericks in the first round of the playoffs last season. Both meetings between these clubs separated by about three hours of highway have gone into OT this season, with the Thunder taking both.
The Mavericks trailed for most of the evening, but repeatedly fought back, usually behind reserve Vince Carter. They led by three points on two occasions in the fourth quarter, but needed a desperation 3-pointer from O.J. Mayo with 2.3 seconds left in regulation to force the extra session.
The Mavericks (17-24) also held a three-point edge in OT but Durant drilled a 3-pointer with 2:05 left to put Oklahoma City back on top, 112-110. Durant scored nine points in overtime, including a floater for a 116-114 lead with 16.5 seconds left.
The All-Star Game starter made all 21 of his free throws, and has hit the 40-point mark in three of his last five games. Durant's previous career best was 51 points against Denver last season.
Durant didn't do it alone. Russell Westbrook added 30 points, six assists and five rebounds. Serge Ibaka grabbed 14 rebounds and picked up a double-double with 11 points.
The Thunder won despite shooting 41.1 percent.
Carter's 29 points paced the Mavs, who saw their season-high four-game winning streak snapped. Carter missed a running 3-pointer at the OT buzzer.
Dirk Nowitzki responded from a slow start to score 18. Mayo also had 18 and dished out seven assists. Backcourt mate Darren Collison scored 15.
The Thunder had the game on the verge of a blowout in the first half, opening up as much as a 14-point lead in the second period. Westbrook and Durant combined for 31 points by halftime, but the pesky Mavs wouldn't go away.
Dallas finished the half with a push led by Carter, cutting the deficit to seven at 53-46. Carter had 12 off the bench, while Collison added 11. The Mavericks were in it despite Nowitzki shooting 1 of 9 in the first half.
Westbrook scored 10 in the first quarter, as the Thunder outscored Dallas, 30-22.
