LeBron James scored 24 points with 12 assists as the Cleveland Cavaliers made more history with a 102-74 win over the Dallas Mavericks on Sunday, extending their winning streak to a franchise record 12 straight. The Cavs, who earlier this week surpassed the club mark for wins in a season, trailed 35-20 in the first quarter and 49-47 at halftime. But Cleveland outscored Dallas 30-11 in the third quarter and 55-25 in the second half to improve to a league-best 35-1 at home. Cleveland is the 61st team to win 60 games in the regular season. Dirk Nowitzki scored 20 for the Mavericks. Celtics 103, Thunder 84: At Boston, Paul Pierce had 27 points and Eddie House scored 14 of his 16 in the second half to lead the Celtics. Glen “Big Baby” Davis had 19 points and 10 rebounds and reserve Mikki Moore scored 12 with 11 boards for Boston. Rajon Rondo had 12 assists to help the Celtics win for the sixth time in seven games despite missing All-Star forward Kevin Garnett, who sat out for 15th time in 19 games to rest a strained right knee. Russell Westbrook scored 23 points and Kevin Durant added 21 for the Thunder, which lost their third straight and fifth of six. Hawks 86, Lakers 76: At Atlanta, Mike Bibby scored 21 points – including an improbable 3 off the top of the backboard – and the Hawks took advantage of a tough outing for Kobe Bryant, knocking the Lakers another game behind Cleveland in the race for the NBA's best overall record. The Lakers had won five straight, locking up the top seed in the Western Conference, but an ailing Bryant had just 17 points on 7-of-19 shooting against Atlanta. Pau Gasol was the only other Los Angeles player in double figures, leading with 21 points, as the Lakers made just 35 percent (28-of-80) from the field. Zaza Pachulia had 11 points and 13 rebounds, leading a strong effort by the thin Hawks bench. The reserves combined for 29 points and 15 rebounds.
