SAN ANTONIO, March 14 (UPI) -- Tim Duncan dominated the inside Thursday and San Antonio survived a late surge to fight off Dallas 92-91 and clinch a spot in the post-season.

The Spurs won their 50th game of the campaign thanks to 28 points and 19 rebounds from Duncan, who because of a sore knee sat out last Tuesday's stunning loss to Minnesota.

San Antonio held an eight-point lead with 2:30 to play, but the Mavericks scored the last seven points of the game.

Dirk Nowitzki brought the Mavericks within one by hitting a jumper with 28 seconds left and Dallas regained the ball after a miss by Manu Ginobili.

Vince Carter, however, misfired on a 3-pointer with a second to play.

San Antonio wrapped up a playoff spot for the 16th straight season. Gary Neal added 16 points for the Spurs and Kawhi Leonard had 12.

Dallas had been riding a season-best, four-game winning streak. Nowitzki led the Mavericks with 21 points and 11 rebounds.
