Celtics 121, Knicks 112

Kyrie Irving had 31 points, nine rebounds and eight assists, leading Boston over host New York on Saturday for its second victory in two nights since the All-Star break.

Irving scored 15 points in a dazzling third quarter and then helped the Celtics finish it off with his passing in the fourth, highlighted by a behind-the-back dish to Jaylen Brown for a dunk that made it 115-106.

Brown had 24 points for the Celtics, who went into the break with three straight losses but came back with a victory in Detroit on Friday.

Trey Burke scored 26 points off the bench for the second straight game for the Knicks, but they couldn’t win this one after beating Orlando on Thursday to end an eight-game skid.

76ers 116, Magic 105

Joel Embiid had 28 points and 14 rebounds, and host Philadelphia extended its season-high win streak to seven with a victory over Orlando.

Six 76ers scored in double figures. Ben Simmons had 17 points and seven assists, and 3-point specialist J.J. Redick added 16 points on 6-for-8 shooting — and just one 3-pointer. Marco Belinelli had 15 points, Robert Covington had 12 and Dario Saric scored 11.

Aaron Gordon led Orlando with 20 points, including four 3s, to go with seven rebounds and seven assists. Evan Fournier scored 16 points, and former Sixer Nik Vucevic had 15 points and nine rebounds for the Magic, who have lost five straight.

Heat 115, Grizzlies 89

Tyler Johnson scored 23 points to lead six players in double figures, and host Miami stopped a three-game slide when it beat reeling Memphis.

The Grizzlies lost their ninth game in a row, the longest active streak in the NBA, and their second in as many nights.

Justise Winslow scored a season-high 17 points for the Heat. Reserve Wayne Ellington went 5 for 10 from 3-point range and scored 15.

Miami’s Dwyane Wade was limited to 18 minutes by foul trouble and scored six points. But the Heat, scrambling for a playoff berth, still managed to win for only the second time in the past 10 games.

Warriors 112, Thunder 80

Kevin Durant scored 28 points for visiting Golden State while avenging an embarrassing home loss to his former Oklahoma City team earlier this month and another on the road in November, leading the Warriors past the Thunder.

Stephen Curry added 21 points with five 3-pointers, nine rebounds, six assists and three steals as Golden State put on the kind of defensive performance coach Steve Kerr has been seeking from the defending champs.

Russell Westbrook had 15 points, 12 rebounds and seven assists for Oklahoma City.
