Miami Heat's Chris Bosh (1) goes to the basket as Charlotte Bobcats' D.J. White (8) watches the play in the first half of an NBA basketball game in Miami, Sunday, Jan. 1, 2012.

MIAMI — Chris Bosh scored 17 of his 35 points in the fourth quarter, LeBron James added 18 and the Miami Heat survived another shaky offensive night to beat the Cleveland Cavaliers 92-85 on Tuesday night.

Bosh made 10-of-16 shots and reached the 30-point mark for the fourth time this season for Miami, which improved to 4-1 against Cleveland since James joined the Heat. The 35 points matched Bosh's high since joining Miami.

Kyrie Irving — Cleveland's No. 1 overall draft pick last year and a friend of James, who the Cavaliers drafted No. 1 in 2003 — scored 17 points on 7-for-11 shooting. Samardo Samuels made his first seven shots and finished with 15 points for the Cavs, who got 11 points and 11 rebounds from Anderson Varejao and 10 from Ramon Sessions.

MAGIC 102, PACERS 83: At Indianapolis, Ryan Anderson had 24 points and eight rebounds to help Orlando cruise past Indiana. Dwight Howard had 14 points and nine rebounds and became the Magic's all-time leading scorer. He came in needing just eight points to break the record.

KNICKS 111, BOBCATS 78: At Charlotte, N.C., Tyson Chandler had 20 points and 17 rebounds as New York snapped a six-game losing streak and handed Charlotte its fifth straight defeat. Chandler shot 9-for-10 from the field as the Knicks won despite a career-low one point from star Carmelo Anthony. Amar'e Stoudemire added 18 points and eight rebounds for the Knicks.

RAPTORS 99, SUNS 96: At Phoenix, Andrea Bargnani returned after missing six games with a left calf strain to score 27 of his 36 points in the second half, and Toronto snapped an eight-game losing streak with their first win over the Suns in eight years. Marcin Gortat had 21 points and 12 rebounds and Steve Nash had 17 points and 14 assists for the Suns.

BLAZERS 97, GRIZZLIES 84: At Portland, Ore., Lionel Aldridge scored 22 points and Marcus Camby had a season-high 22 rebounds as the Trail Blazers snapped a seven-game winning streak by Memphis.

WASHINGTON — Seeking different strategies at both ends of the court and improvement from a roster filled with young players such as John Wall, the NBA-worst Washington Wizards fired coach Flip Saunders on Tuesday after a 2-15 start and replaced him with assistant Randy Wittman.

"I'm not the miracle-maker here," said Wittman, who was given the top job through the end of the season. "We've got to change our outlook on how we play. Sometimes, when you have such a young team, players get a little confused, I think, when the word 'development' is used; that they're going to be able to develop just playing. Development has to happen on the practice floor."

The Wizards fell to 0-7 on the road with a 20-point loss to the Philadelphia 76ers on Monday. Washington's next game is at home tonight against the Charlotte Bobcats.

A 25-minute news conference Tuesday with Wittman and team president Ernie Grunfeld ended with Grunfeld answering a question by saying: "Just because you're losing, you're not a loser."

It began with him explaining the coaching switch.

"I felt like at this time, our players were not responding, and I think we needed a different voice. This doesn't change our overall plan, which always has been very transparent for us, which is to build through the draft, get salary-cap space going forward and develop our young players," Grunfeld said. "They probably haven't developed as quickly as we'd like for them to develop. That's something we need to continue to work on."
