Miami ? Dwyane Wade didn’t pause for a second when he was asked about his plans for Father’s Day.

“Winning the game,” he said.

Wade scored 43 points, the final two on a pair of free throws with 1.9 seconds left in overtime, as the Miami Heat took advantage of a mistaken timeout and won their third straight game in the homey series, 101-100 over the Dallas Mavericks on Sunday for a 3-2 lead in the NBA finals.

Wade’s free throws gave him a finals-record 21 and capped perhaps the most memorable game of this remarkably tight postseason. His latest virtuoso performance sent the teams to Dallas for Game 6 on Tuesday night. Game 7, if necessary, will be Thursday night.

When the Mavericks’ final shot – because of Josh Howard’s error, all they could manage was a half-court heave by Devin Harris – was off the mark, streamers fell from the top of AmericanAirlines Arena, hosting its final game of the season.

“We can smell it,” Wade said. “Dallas plays well at home, but we are a confident bunch so we’ll see what happens.”

When it ended, Dallas owner Mark Cuban ran onto the floor, complaining about the final two seconds when there was confusion over Dallas’ final timeout.

Cuban, wearing a blue jersey bearing the name of suspended Dallas reserve Jerry Stackhouse, stood with his hands on his hips in disbelief as the Mavericks headed to the locker room to begin getting ready for Game 6.

Wade made 21-of-25 free throws, matching Dallas’ total, and came through again when the Heat needed their shooting star most.

After Nowitzki’s jumper with 9.1 seconds to go gave the Mavericks 100-99 lead, Wade took an inbounds pass, wove and dribbled his way seemingly all over Florida and was fouled on a drive to the basket by Nowitzki.

Wade made the first, and the officials awarded Dallas a timeout even though Mavericks coach Avery Johnson was arguing that he didn’t want one until Wade’s second attempt. The officials huddled and said the Mavs had asked for a timeout and gave them their last one.

“We gave the signal, ‘Second free throw, timeout.’ One of our players was saying timeout. I said, ‘Yeah, after the second one,”‘ Johnson said.

“Pretty much most people who have ever been involved in the NBA for 20, 30 years, know we wouldn’t want one anyway with only one timeout,” he said. “So we were pretty dumbfounded that that couldn’t get relayed.”

Crew chief Joe Crawford, speaking for the officials, said: “Josh Howard goes to Joe DeRosa and not only once, but twice asks for timeout. Forced to call it, simple as that.”

The timeout took away Dallas’ ability to inbounds the ball at halfcourt, costing them 45 precious feet. Wade then knocked down his second free throw, and when Harris’ shot was way off, this series had its latest controversy.

On the way to the locker room, Nowitzki kicked a stationary bike and Cuban spent another 10 minutes pleading to anyone who would listen.

The Heat, who finished 10-1 at home in these playoffs, are now one win away from that victory parade down Biscayne Boulevard that Shaquille O’Neal promised when he signed with the Heat.

O’Neal scored 18 points with 12 rebounds, but he was just 2-for-12 from the free-throw line.

Jason Terry had 35 points for the Mavericks. Howard added 25, and Nowitzki had 20.
