Celtics grind past nemesis Heat in double overtime

BOSTON — Paul Pierce hit a go-ahead jumper with 31 seconds left in the second overtime and the Boston Celtics beat the Miami Heat 100-98 on Sunday, then learned All-Star point guard Rajon Rondo will miss the rest of the season with a knee injury.

Rondo will have surgery for a torn anterior cruciate ligament in his right knee. He was hurt late in Boston's 123-112 loss, also in two overtimes, to the Atlanta Hawks on Friday night.

Kevin Garnett had 24 points and 11 rebounds, and Pierce added 17 points, 13 rebounds and 10 assists for the Celtics, who ended a six-game losing streak, their longest in six seasons.

LeBron James scored 34 points for the Heat, who had won four in a row.

LOS ANGELES — Kobe Bryant had 21 points, 14 assists and nine rebounds, Steve Nash added seven of his 17 points in the final 5 1/2 minutes, and the Lakers held off the NBA-leading Thunder.

Pau Gasol scored 16 points in a reserve role as the Lakers picked up the most impressive victory of their thoroughly unimpressive season, coolly maintaining a small lead down the stretch of their second straight win after a four-game skid.

Kevin Durant scored 35 points and Russell Westbrook had 17 points, 13 assists and nine rebounds for the road-weary Thunder, who finished their longest trip of the season at 3-3.

NEW YORK — Carmelo Anthony tied a franchise record with nine 3-pointers, then converted a go-ahead, three-point play with 12.5 seconds left to cap a 42-point night and lead the New York Knicks to a victory over the Atlanta Hawks.

Amare Stoudemire and J.R. Smith each had 18 points for the Knicks.

Jeff Teague scored 27 points for the Hawks. Josh Smith added 20 and Al Horford had 16.
