The AP reports: The Charlotte Bobcats finally lost, but are still in the playoff hunt. The San Antonio Spurs won again and now await what might be a playoff preview. Tim Duncan had 18 points and 11 rebounds, and the Spurs halted Charlotte’s franchise-record winning streak at six with a 100-86 victory Tuesday night. Roger Mason and Tony Parker added 21 points apiece for the Spurs, who will take a three-game winning streak into Thursday’s home game against the Los Angeles Lakers, a marquee meeting of the Western Conference’s top two teams… Raymond Felton had 15 points and Gerald Wallace 14 for Charlotte.
