MIAMI (AP) Down by 16 points in the second half, the Dallas Mavericks were in big trouble.
For a couple minutes, anyway.
The Mavericks pulled off the ultimate turnaround - going from the receiving end of a blowout to administering one, and doing so with almost unbelievable speed and ease.
A 37-2 run was more than enough, and the Mavericks embarrassed Miami with a 93-72 win on Friday night. It was the 600th regular-season victory for Dallas coach Rick Carlisle and another troubling chapter in the erratic story of the Heat season.
''At some point you say, `This is enough,''' Heat coach Erik Spoelstra said. ''We don't know how we get into these situations, but it will change.''
Dallas trailed 49-33 in the third quarter.
The score the rest of the way: Dallas 60, Miami 23.
No Dwyane Wade, no Luol Deng, and no chance for the Heat once the run started for the Mavericks.
Charlie Villanueva scored 14 of his season-high 20 points after halftime for Dallas, which got 12 points apiece from Dirk Nowitzki and Monta Ellis, and an 11-point, 13-rebound effort from Tyson Chandler.
''You've got to beat the guys that are out there and Miami is well-coached, they're athletic, they're going to play hard, so we had to take this game,'' Nowitzki said. ''They weren't going to give it to us and that's what we did there in the second half.''
Miami's Hassan Whiteside had 16 points and 24 rebounds, matching the second-most for a single game in franchise history. James Ennis scored 15, Chris Bosh had 12 and Mario Chalmers scored 10 for the Heat, who now head out on a weeklong road trip clinging to the No. 7 spot in the Eastern Conference.
''Speechless,'' Whiteside said, when asked about the second-half collapse.
Whiteside was dominant early with 14 rebounds in the first 8 minutes alone, and the Heat led 45-33 at the half. When Whiteside went out late in the third, Miami led 60-51.
When he returned, Miami was down 72-60, having been outscored 21-0 during his absence - and the run just kept going.
So now, without Wade on Friday night - and probably for a few more games - because of his strained hamstring, the Heat need ''all hands on deck,'' Spoelstra said.
Some of those hands on Friday?
Norris Cole shot 1 for 10, Shawne Williams shot 1 for 6, Danny Granger shot 0 for 6. Take away Whiteside's 7-for-11 night, and the rest of the Heat shot 22 for 77 - 29 percent.
''Just a tough one,'' Heat guard Tyler Johnson said.
Mavericks: It was Villanueva's first 20-point game since he finished with 21 against San Antonio on Feb. 8, 2013. ... F Chandler Parsons missed the game because of an illness. It forced the Mavs into using their 10th lineup of the season. ... Dallas went from down 16 to up 26 at one point in the second half, a 42-point swing in about 20 minutes.
Heat: Wade will not accompany Miami on at least the first part of its weeklong road trip that starts Sunday in Boston, staying home to continue rehabbing his strained hamstring. ... Deng (calf) is improving and will travel, Spoelstra said after Miami used a 19th lineup in 46 games. ... Johnson made his home debut, getting three assists in the second quarter.
Retired NBA player Shane Battier, who ended his career with the Heat and won two championships in Miami, was working again in the arena on Friday night. Battier, who has kept his South Florida home, got a loud ovation from early arriving fans when he walked onto the court about 40 minutes before tip-off.
FIRST QUARTER BLANKS
Dallas won despite shooting just 18 percent in the first quarter. Miami led 15-13 after the opening 12 minutes, despite shooting 23 percent - days after shooting 71 percent in the first quarter against Milwaukee and actually trailing 30-29 after that period.
Mavericks: At Orlando on Saturday.
Heat: At Boston on Sunday.
