NEW YORK -- LeBron James alternated fouls and fumbles, the crowd howling in delight with every one of his mistakes.
Finally forced to sit for most of the third quarter, James wasn't mad, and the Miami Heat weren't worried.
"We had the lead going into the fourth quarter on the road, and then we had the best player in the game coming in. So we were fine," Dwyane Wade said.
And James, over the final 12 minutes, was exceptional.
James scored 32 points, including eight straight to start the fourth quarter and break open the game, and the Heat took a 3-0 series lead, sending the New York Knicks to an NBA postseason-record 13th straight loss, 87-70, on Thursday night.
James had 17 points in the final period for the Heat, who held the short-handed Knicks to eight field goals in the second half and will go for the sweep Sunday afternoon.
"He just has to stay with it," Heat coach Erik Spoelstra said. "He had some turnovers, he had some mistakes but he was able to keep his head in it."
Wade added 20 points for the Heat and Mario Chalmers had 19.
Carmelo Anthony scored 22 points but shot 7 of 23 for the Knicks, who are playing without Amare Stoudemire, Jeremy Lin and Iman Shumpert and needed a super effort from Anthony that he didn't come close to providing.
"When you can't score the basketball, that makes the game extremely hard, no matter how much defense we go down there and play," Anthony said.
Thunder goes up 3-0
DALLAS -- Kevin Durant finally found his postseason shooting touch to get Oklahoma City off to a quick start, and the Thunder never trailed on the way to a 95-79 victory over the Dallas Mavericks for a commanding 3-0 series lead over the defending NBA champs.
After two close games on their home court, the young Thunder ran away with Game Three.
They will run away with the first-round series with one more win. Game Four is Saturday in Dallas.
Durant finished with 31 points on 11-of-15 shooting. Russell Westbrook added 20 points for the Thunder.
