He made sure Miami didn't waste its chance Sunday to knock off the NBA-leading Spurs.
Wade had 13 of his 28 points in the fourth quarter, including a jumper with 25.1 seconds left, helping Miami beat San Antonio 96-92 -- the first time the Heat downed the Spurs since Feb. 1, 2002.
"It's a big win," said Wade, who hit five of his final seven shots and added six assists and five rebounds. "Everything didn't go smooth for us, but what's important is we beat a great team that's playing well right now."
The game between conference leaders -- San Antonio's 40-12 record leads the NBA, and Miami's 39-14 mark has it seven games ahead of Detroit in the East -- was classic, with 22 lead changes and 22 ties and with neither team ever leading by more than six points.
Back and forth they went until the Heat stepped up in the final minutes.
"That is the best I have felt about our team in a long time," Heat coach Stan Van Gundy said. "Not just because we got a win against a great team, but the way we got it. It was a very hard fought game and we really had to battle to win."
Manu Ginobili, who led San Antonio with 24 points, put the Spurs ahead 85-83 with 4:15 remaining on a layup. Shaquille O'Neal hit a free throw for Miami 20 seconds later and then caught a long outlet
from Wade, spun and found Damon Jones for a 3-pointer to put Miami up for good with 3:06 left.
The Heat became just the fifth team to overcome a halftime deficit against the Spurs. San Antonio was 34-4 when leading at the break this season.
Wade had six points in the final 2:47, including a driving layup to put Miami up 93-87 with 1:33 left. Ginobili had five straight to draw the Spurs within one, but Wade's jumper with 25.1 seconds left sealed it for the Heat.
"He's a great player and he was very aggressive tonight," said Spurs guard Tony Parker, who had 22 points -- his fifth straight game of at least 20 points. "He had some huge baskets down the stretch."
O'Neal added 27 points and seven rebounds for Miami, which shot 52.2 percent from the floor, compared to 39.2 percent by San Antonio. Eddie Jones chipped in with 12 points even though he played much of the game with a broken left index finger.
Tim Duncan had 17 of his 20 points after halftime for the Spurs, who got 11 rebounds from Rasho Nesterovic. The Spurs shot 52.9 percent (9-for-17) from 3-point range and just 35.5 percent (22-for-62) from two-point land.
"They made a couple of big shots. We didn't," Ginobili said. "That's why they won the game."
The sellout crowd included former Heat center Alonzo Mourning. He agreed to a buyout worth between $9 million and $10 million on Friday with the Toronto Raptors, who acquired him in the trade that sent Vince Carter to New Jersey.
Mourning, who never played for the Raptors and has said he'd like to sign with the Heat once he clears waivers Tuesday, wouldn't comment Sunday. An arena security guard sat on the stairs next to Mourning and kept people away. Heat officials also again declined comment on Mourning.
"I'll welcome him if he comes," O'Neal said after the game. "It'll be another big body we can use."
The Heat didn't need their former franchise player Sunday, outrebounding the Spurs 41-38 and holding a 48-34 edge in points in the paint -- only the ninth time San Antonio has been outscored around the basket this season.
The game got off to a bit of slow start, with San Antonio leading 42-41 at the break.
Ginobili hit two free throws to cap an 8-0 spurt and give San Antonio a 37-31 lead with 3:47 left in the half. Miami responded with 10 unanswered points; O'Neal punctuated the run with a dunk that put the Heat ahead 41-37 with 53.9 seconds left.
But Parker had the final five points, including a 3-pointer with 0.7 seconds left before intermission. Miami, however, held Parker to a 2-for-7 shooting performance in the second half.
"We made too many mistakes down the stretch and didn't play smart the last three or four minutes," Parker said.
Parker had two assists, giving him 1,500 in his regular-season career. He's on his longest 20-plus scoring run since six straight games two seasons ago. ... Wade scored in double digits for the 27th straight game, extending his career-long streak in that department. ... Lenny Kravitz, who makes his home in South Florida, sat courtside, three seats to the right of Heat owner Micky Arison. ... Van Gundy is now 50-17 in home regular-season games. ... Eddie Jones said he'll have to wear a splint for at least three weeks to protect his finger.
