SAN ANTONIO — Instead of watching their season-opening winning streak come to a messy end, the New York Knicks served notice that they can’t be counted out in the fourth quarter.

Raymond Felton scored 25 points and New York stayed undefeated by rallying late to beat the San Antonio Spurs 104-100 on Thursday night.

Trailing by 12 with seven minutes left in the game, the Knicks (6-0) closed on a 22-11 run to remain the NBA’s only unbeaten team.

“It shows me that this team is for real,” New York coach Mike Woodson said. “We beat a great team tonight — a well-coached team. It’s the first time I’ve ever won in San Antonio, so I feel pretty good about that. It’s tough to win here.”

J.R. Smith added 17 points, Jason Kidd had 14 and Tyson Chandler 13 for the Knicks. Tony Parker led San Antonio (7-2) with 19 points and 12 assists.
