DALLAS — O.J. Mayo scored 32 points, his second consecutive 30-point game at home, and the Dallas Mavericks used a fourth-quarter surge for a 114-91 victory over the Portland Trail Blazers on Monday night.

Mayo, one of a trio of Mavericks newcomers who scored in double figures, made six 3-pointers on his 25th birthday and capped his night with a running dunk with 1:18 left. He scored 30 in the home opener two nights earlier.

Chris Kaman had 16 points on 8-of-10 shooting while Darren Collison had 14 points and 13 assists with only one turnover for the Mavericks. It was Collison’s second consecutive double-double.

The Trail Blazers are coached by Terry Stotts, a Mavericks assistant the past four seasons under Rick Carlisle.

LaMarcus Aldridge, a Dallas native, and Wesley Matthews had 20 points each for Portland. Nicholas Batum had 14 points, while J.J. Hickson had 11 rebounds.

Dallas led only 85-83 with 10:17 left before ending the game with a 29-8 run, even using plenty of its bench players. Kaman, who was 8-of-9 shooting in his Dallas debut, started that run by making his sixth consecutive shot.

The Mavericks shot 62 percent (48 of 78) from the field, and have been better than 60 percent in both home games.

The only sour note for Dallas, which is already without Dirk Nowitzki (recovering from arthroscopic knee surgery), was Shawn Marion leaving the game in the third quarter with a strained right knee. He had eight points and seven rebounds in 24 minutes.

Mayo hit 3-pointers from the right wing and then the left wing earlier in the third quarter. He hit another from long range to put Dallas up 70-67 with 5 1/2 minutes left in the quarter.

Knicks 10076ers 84

PHILADELPHIA — Carmelo Anthony scored 21 points and JR Smith had 17 to lead the New York Knicks to a 110-88 win over the Philadelphia 76ers on Monday night.

Raymond Felton scored 16 points and Tyson Chandler had 14 to lead the Knicks to their first 3-0 start since the 1999-2000 season. The Knicks beat the Sixers 100-84 on Sunday in the opener of the home-and-home series.

The Knicks busted the game open in the third quarter, stretching the lead to 21 points. They got a surprising third from 38-year-old Rasheed Wallace, who scored eight points and hit a couple of 3-pointers, including a 26-footer at the buzzer to end the quarter.

After a solid first, the Sixers fell apart, and got nothing going with their set offense. Jrue Holiday led them with 17 points.

Heat 124Suns 99

MIAMI — LeBron James had 23 points and 11 rebounds, Dwyane Wade scored 22 points and Miami beat Phoenix.

Chris Bosh finished with 18 points and Ray Allen had 15 for the Heat, who are averaging 111.8 points in their first four games. Allen became the 24th player in NBA history to eclipse the 23,000-point mark when he made a free throw with 1:01 left in the third quarter.

Shannon Brown led Phoenix with 18 points off the bench, making five 3-pointers. Luis Scola had 15 points, Goran Dragic finished with 13 points and nine assists, and Marcin Gortat scored 12 for the Suns.

The Heat put the game away with a 23-6 run in the third, a spurt fueled by 10 points from James and five 3-pointers in a span of less than 5 minutes.

T-Wolves 107Nets 96

NEW YORK — Rookie guard Alexey Shved and Chase Budinger led a furious rally from 22 points down, and Minnesota stunned Brooklyn.

Shved made the go-ahead basket with 2:35 remaining and had a pair of 3-pointers in the fourth quarter after going scoreless for the first three. The Timberwolves scored the final 11 points in an impressive rally on the second night of back-to-back games. Seemingly out of the game early in the second half, they overwhelmed the Nets in the fourth quarter with a brilliant effort from their bench.

Shved, a point guard from Russia, hit from in the lane, then Nikola Pekovic scored inside and Budinger made a 3-pointer with 38 seconds to go, making it 103-96 in front of a stunned crowd in the second game at the new Barclays Center.
