Carmelo Anthony traded from New York Knicks to Oklahoma City Thunder.

NEW YORK — After scoring more than 10,000 points for five coaches over seven seasons without all that much to show for it, Carmelo Anthony is finally leaving New York.

The New York Knicks on Saturday agreed to trade Anthony, a 10-time NBA AllStar and one of the league’s great offensive players, to the Oklahoma

City Thunder in exchange for Enes Kanter, Doug McDermott and a second-round draft pick, according to a league official briefed on the negotiations.

The deal, completed just two days before the start of Knicks training camp, will allow Anthony, 33, to join forces in Oklahoma City with two other marquee players — Russell Westbrook, the NBA’s reigning most valuable player, and Paul George, a four-time All-Star — as the Thunder begin a wildly ambitious bid to challenge the supremacy of the Golden State Warriors, who have claimed two of the last three NBA championships and are strong favorites to win another next season.

At the same time, the Knicks can finally close the chapter on Anthony’s turbulent tenure in New York and try to move on without him. Anthony, who desperately wanted out of New York, had been determined to join the Houston Rockets. But as training camp neared, he agreed to waive his no-trade clause for a couple more teams, including the Thunder.

It will not take Anthony long to see his old team again: The Knicks are scheduled to play their season opener in Oklahoma City on Oct. 19.

With Saturday’s deal, the Knicks signaled the continuation of a youth movement centered on Kristaps Porzingis, their 22-year-old power forward. But their defense remains in some doubt.

Kanter, a 25-year-old center from Turkey, averaged 14.3 points in 21.3 minutes a game for the Thunder last season. But Billy Donovan, coach of the Thunder, had such little faith in Kanter’s defensive abilities that he could not keep him on the court in a playoff series against the Rockets last season.

In May, Kanter made international headlines when he was detained in Romania after the Turkish government canceled his travel documents.

McDermott, a 25-year-old forward, averaged 9 points a game last season.
