BOSTON -- Carmelo Anthony scored 21 points and the New York Knicks held on after blowing most of a 26-point lead to beat the Boston Celtics 88-80 in Game 6 on Friday night and advance in the postseason for the first time since 2000.
Iman Shumpert scored 15 of his 17 points in the second half, when the Celtics cut a 75-49 deficit to four points. But Anthony made a jumper to give New York an 81-75 lead and then sank a 3-pointer, then J.R. Smith converted a three-point play to restore the double-digit lead the Knicks had nursed most of the game.
Jeff Green scored 21 points for the Celtics, who had rallied from a 3-0 deficit in the series and had a chance, at home, to force a decisive seventh game.
No NBA team has advanced in the playoffs after losing the first three games.
Paul Pierce scored 14 points on 4-for-18 shooting, making one of nine 3-point attempts. Anthony also struggled from in- and outside the arc, going 7 for 23 from the floor and missing his first five 3-point attempts -- that was 20 in a row in the series -- before sinking the key basket with 1:43 to go.
The Knicks had not won a playoff series since Patrick Ewing and Latrell Sprewell (and current backup center Marcus Camby) helped them reach the 2000 Eastern Conference finals.
Kevin Garnett had 15 points and 10 rebounds for the Celtics, who now face another offseason of talk whether to break up the aging core that won the franchise’s record 17th NBA title in 2008 and returned to the finals two years later. Reserve Jason Terry scored 14 points -- the only points the Celtics got from their bench.
