The AP reports: LeBron James scored 21 points before spending part of the fourth quarter on the bench playing air guitar and dancing as the Cavs avenged an embarrassing loss to one of the league’s weaker teams by thumping the rival Wizards 98-86 on Wednesday night to improve to 38-1 at home. The win lowered the Cavaliers’ magic number for locking up home-court advantage for the Eastern Conference playoffs to one. A Cleveland win on Friday night at Philadelphia or a Boston loss to Miami will give the Cavs (63-15) the East’s top seed… Mo Williams scored 14 points and Zydrunas Ilgauskas had 13 rebounds for the Cavs, who for the first time in four years will not see the Wizards in the first round of the postseason… Nick Young scored 16 to lead the Wizards, who stunned Cleveland last week and handed the Cavs two of their 15 losses this season. Washington’s Gilbert Arenas didn’t play, choosing to rest his surgically repaired right knee. Arenas’ return had sparked the Wizards to their upset over the Cavs last week.
