SYRACUSE, N.Y. — Jason Richardson made a three-point play and hit a pair of 3-pointers to start the fourth quarter, and the Philadelphia 76ers held on to beat the New York Knicks 98-90 on Monday night in an exhibition game in the Carrier Dome, spoiling Carmelo Anthony’s return to his college roots.

It was an outcome Anthony was unaccustomed to in the Carrier Dome. As a freshman at Syracuse in the 2002-03 season, he led the Orange to a 17-0 record at home in the dome en route to the national championship.

Anthony and Raymond Felton each finished with 23 points for the Knicks (2-3). Anthony also had six rebounds, five assists and four steals. Felton was 5 of 7 on 3-pointers, and Chris Copeland added 15 points.

Richardson had 23 points and Thaddeus Young 22 for Philadelphia (6-1).

Philadelphia led by as many as 24 on Young’s floater in the lane early in the third period before the Knicks came alive from beyond the arc. Felton hit a pair of 3-pointers, and Anthony and Jason Kidd each chipped in with one to narrow the lead to 74-65.

Anthony’s stepback 3 in the final minute of the period made it 76-72 entering the fourth, and it could have been more. Fouled on the shot by Damien Wilkins, Anthony missed the free throw and an ensuing 3 after Steve Novak corralled the rebound. Novak snared the rebound of Anthony’s miss and also misfired from beyond the arc before the buzzer.

New York pulled within a basket three times before Richardson gave the Sixers some breathing room.

The Sixers gained a big lead in the first half with a 19-6 spurt that started with Spencer Hawes’ 3-pointer from the left wing in the final minute of the opening period. That broke a 23-all tie and the Knicks then went cold, missing five shots and committing a turnover.

Hawes hit a hook in the lane and Royal Ivey and Nick Young hit consecutive baskets to give Philadelphia a 34-25 lead. Richardson and Ivey completed the run with 3-pointers, giving the Sixers a 42-29 lead with 7:09 left in the second.

Two free throws by Tyson Chandler narrowed the lead to 11, but after Felton’s 3 closed the gap to 48-36, the Sixers ended the half with a 14-8 rush to lead by 18.

Anthony started the game with a turnaround jumper to send the Knicks on a 7-0 surge. The Sixers answered with a 14-0 run keyed by five straight points from Richardson and a 3 from the left corner by Ivey that completed it.
