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 Eastern Conference series lead, sending the host 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, hitting consecutive three-pointers in the fourth quarter when the Heat finally brought some beauty to what had been an ugly game.
"My mindset was to make plays for our team to try and help us win down the stretch," James said. "I was able to come in and make some plays to help us win."
Carmelo Anthony scored 22 points but shot 7-for-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.
The Knicks broke the record set by Memphis from 2004-06. They haven't won a playoff game since April 29, 2001, Game 3 of a best-of-five series against Toronto.
No NBA team has overcome a 3-0 deficit.
Chris Bosh had nine points and 10 rebounds hours after the birth of his first child. He flew to New York with the Heat on Wednesday, then quickly hopped on a flight back to Miami after learning his wife was in labor. He returned Thursday afternoon following the birth of his son, arriving at the arena about 30 minutes before the game.
Lin is practicing again after knee surgery but is not ready to return. Shumpert tore a knee ligament in Game 1, and Stoudemire is hoping the hand injury he sustained punching a fire extinguisher case following Game 2 is healed enough to let him play Sunday.
At Dallas, Kevin Durant scored 31 points on 11-for-15 shooting, and the Thunder never trailed en route to a 95-79 victory over the Mavericks for a commanding 3-0 Western Conference series lead over the defending NBA champs. Game 4 is Saturday in Dallas.
Dirk Nowitzki had 17 points to lead Dallas.
