Thunder Top Mavs to Sweep Preseason December 21, 2011 at 4:10 AM CST - Updated June 26 at 3:58 AM OKLAHOMA CITY (AP) - The Oklahoma City Thunder took some satisfaction in sweeping Dallas during the NBA's shortened preseason - even if it wasn't the Western Conference finals. James Harden had 13 points, seven rebounds and five assists, Russell Westbrook added 12 points and the Thunder beat the Mavericks for the second time in three days, winning 87-83 on Tuesday night. Oklahoma City won 106-92 at Dallas on Sunday, although Dirk Nowitzki and Jason Kidd didn't play for the Mavericks in that game. Both saw action Tuesday but mostly struggled. Jerome Randle led Dallas with 17 points while Brandan Wright had 12. Oklahoma City star Kevin Durant, a 2-time NBA scoring champ, had 10 points on 4 of 9 shooting in 21 minutes. He sat out the entire fourth quarter, as did Nowitzki and Kidd. Copyright 2011 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
