MIAMI >> Maybe in a video game. Possibly in the pregame layup line.

But shoot this way in the NBA Finals, against the two-time defending champions?

"It’s not something you can plan for," San Antonio reserve Manu Ginobili said. "There was no magic plays. We just moved the ball and every shot went in."

Not quite every shot. But just about.

Kawhi Leonard scored a career-high 29 points, and the Spurs made a finals-record 75.8 percent of their shots in the first half in a 111-92 victory over the Miami Heat on Tuesday that gave them a 2-1 series lead. 

The Spurs made 19 of their first 21 shots and finished 25-for-33 in the first half, bettering the 75 percent shooting by Orlando against the Lakers in the 2009 finals.

"It’s a hit-or-miss league," Miami’s Dwyane Wade said.

The Spurs didn’t do much missing.

"I don’t think we’ll ever shoot 76 percent in a half ever again," Spurs coach Gregg Popovich said.

The Spurs led by as much as 25 and were only briefly challenged in their second lopsided victory in the series.

LeBron James and Dwyane Wade had 22 points for the Heat, who host Game 4 on Thursday.

Returning to the arena where they were oh-so-close to winning a fifth championship last year, the Spurs came out playing like they were trying to build a lead that was impossible to blow.

They shot 13-for-15 and led 41-25 lead after the first quarter, then hit their first six shots of the second in front of a stunned crowd in Miami to go ahead 55-30.

Leonard scored only 18 points in the first two games, looking frustrated while getting into foul trouble trying to defend James in Game 2. But he had his outside shot working early, making his first six shots and finishing 10-for-13 from the field.

"I just found a rhythm and my teammates found me the ball. I made shots," Leonard said.

The last three NBA seasons ended in this building, the last two followed by Heat championship parades.

The Spurs nearly canceled the last one, building a five-point lead in the final half-minute of regulation of Game 6, a title seeming so certain that workers were already making preparations around the court. 

But the Heat rallied to win in overtime and took Game 7, leaving the Spurs with a summer to think about the one that got away.

They’re in good shape to get another chance.

With the league scrapping the 2-3-2 format for the NBA Finals –in which the lower seed played three consecutive home games — the Spurs would have a chance to wrap it up in San Antonio on Sunday in Game 5 if they can win Thursday.

Chris Bosh took only four shots and scored nine points for the Heat, who for the second straight year will have to overcome a 2-1 finals deficit after being blown out in Game 3.

This rout came on their home floor, where they had been 8-0 this postseason and had won a franchise-record 11 in a row since the Spurs beat them in Game 1 last year.

San Antonio inserted Boris Diaw into the lineup, countering Miami’s small lineup and creating more ball movement that clearly helped Leonard. The game got off to a crisp start, with the Spurs making their first five shots and Miami opening 4-for-4.

Turned out the Spurs were just getting started.

Coach Erik Spoelstra planned to communicate with James to make sure there were no lingering problems from the cramps that forced him to miss the final minutes of the opener. But there was no way he could rest James early, since he was the only one keeping the Heat in the game. He had 14 of their first 20 points, but even James couldn’t keep up with the Spurs’ pace.

The Spurs "came out at a different gear than what we were playing at, and it just seemed we were on our heels the most part of the first half," Spoelstra said.

San Antonio led 71-50 at halftime. It was the first 70-point first half in the finals since the Lakers scored 75 against Boston in Game 2 in 1987.

The Heat finally got into it in the third, running off 10 straight points to cut a 17-point deficit to 81-74 on a drive by Norris Cole, who had replaced an ineffective Mario Chalmers.

That was as close as Miami would get, as the Spurs pulled away in the fourth.
