CLEVELAND >> Kevin Durant released his deep shot, the one he always makes in his dreams.

As the ball hung in the air, his plan to win a championship, Golden State’s grip on the series, Cleveland’s last-gasp attempt to defend its title, all of it was on the line.

Perfect.

Durant drained the shot of his professional life — a 3-pointer over LeBron James with 45.3 seconds left — and scored 31 points as the Warriors, pushed harder than they have been throughout their pristine postseason, moved within one win of a title and payback by rallying to beat the Cleveland Cavaliers 118-113 tonight to take a 3-0 lead in the NBA Finals.

The Warriors trailed by six with three minutes left before Durant, criticized for leaving Oklahoma City last summer to chase a championship, brought them back, scoring 14 in the fourth.

“He took over,” Warriors coach Steve Kerr said. “You can tell, he knows this is his moment. He’s been an amazing player in this league for a long time, and he senses this is his time, his moment, his team.”

With their 15th straight win, the Warriors now have the longest postseason streak for any team in the four major professional sports.

But that means little to Golden State’s players, who with a win in Game 4 on Friday night can exorcise those haunting demons from last June when the Warriors blew a 3-1 lead in the Finals to the Cavaliers.

No team has ever overcome a 3-0 deficit, and it doesn’t appear any team is equipped to hang with these Warriors, who may go down as one of the best ever.

“It’s not over,” Durant warned. “The job’s not done. I don’t want to relax. This is a crazy game, anything can happen.”

Klay Thompson added 30 points and Stephen Curry had 26 for this California Dream Team now one win from its second title in three years.

James shook off a knee-buckling blow to the chin while scoring 39 and Kyrie Irving added 38 for the Cavs, who took a 113-107 lead with 3:09 left on J.R. Smith’s 3-pointer.

Curry hit a layup and after both James and Irving missed for the Cavs, Durant dropped his 3 — a shot that could be the one most remembered in this magnificent run by the Warriors.

“All I was looking at was the bottom of the net,” Durant said. “I saw he (James) was playing his heels behind the 3-point line. I’ve been working on that shot my whole life. To see that go in, that was liberating, man. We’ve got one more to go.”

After Golden State went up, Irving missed a 3 from his favorite spot on the right side and the Warriors closed it out with four free throws in the final 12.9 seconds before celebrating briefly on the floor and then charging down the hallway to their locker room.

After winning Games 1 and 2 by a combined 41 points at home, the Warriors had to scrap for all 48 minutes to take down the Cavs, who will need a similar effort to avoid being swept by a team with few — if any — weaknesses.

“It’s the most firepower I’ve played in my career,” James said. “I’ve played against some great teams, but I don’t think no team has had this type of firepower.”

James and Irving were relentless in the second half and it appeared they had done enough to get Cleveland over the top and perhaps back in the series.

Durant, though, was not going to be denied. Not after getting this close, not after enduring so much heat for turning his back on the Thunder, not with a chance to put the Cavaliers in an insurmountable hole.

The 7-footer finished 10 of 18 from the field with eight rebounds and four assists. Curry, who has benefited more than any other player by Durant’s arrival and is healthy in these Finals, added 13 rebounds and six assists.

With Kerr back on the bench for the second straight game after battling back pain, Golden State, which made a record 9 3-pointers in the first quarter and finished 16 of 33 behind the arc, also got just what it needed from its reserves as Andre Iguodala had several big plays, none bigger than stripping James of the ball on a potential tying 3-pointer with 12.6 seconds left.

Cleveland had collapsed in the third quarter of the first two games, letting the Warriors run away and hide.

Irving didn’t let that happen.

Showing off his ability to spin in shots high off the backboard, Irving scored 16 in the third and the Cavs held the Warriors to 22 points in their lowest scoring output in any quarter in this postseason.

The Cavaliers, though, couldn’t get far enough ahead in the fourth to get comfortable and the Warriors kept chipping into their lead before Durant’s defining 3-pointer.

James was knocked flat in the first quarter, when he accidentally got blasted in the chin by teammate Tristan Thompson’s shoulder. A hush fell over Cleveland’s crowd as the three-time champ laid in the foul lane like a boxer sprawled on the canvas. James shook it off, got up and moments later drove for a layup.

Golden State landed the next blows, but the Cavs kept coming back and were moments away from climbing back and maybe mounting another comeback.

With the flick of his wrist, Durant shot them down.
