The AP reports: LeBron James scored 33 points—four more than his good buddy Dwyane Wade—and took on the challenge of guarding the NBA’s leading scorer down the stretch as the Cavaliers remained the league’s only unbeaten team at home with a 93-86 win over the Miami Heat on Sunday night… Mo Williams scored 20 before fouling out and Ben Wallace had 14 rebounds for the Cavs (26-4), who won their sixth straight. In the final seconds, Wallace and Varejao played a game of volleyball over the basket, tipping missed shots repeatedly before one dropped through to seal Cleveland’s win… Miami rookie G Mario Chalmers strained his right hamstring in the fourth.
