LeBron James made a three-pointer to force overtime before the Los Angeles Lakers moved to the brink of a series victory in the NBA play-offs.

The NBA’s four-time Most Valuable Player levelled the score with 13 seconds left against the Houston Rockets and almost clinched victory as he hit the rim with a three-pointer on the buzzer.

But the Lakers went on to win 112-108 in overtime to claim a 3-0 lead in the best-of-seven first round of the play-offs.

James, 41, again stepped up in the absence of the injured Luka Doncic and Austin Reaves, claiming a team-high 29 points and 13 rebounds.

Marcus Smart also recorded a double-double, scoring eight of his 21 points in overtime and adding a team-high 10 assists.

“With two of our best players down, we’ve got to play desperate,” said Smart. “We’ve got to be the most desperate team.

“That’s how we’ve been playing, and that’s how we’re winning, right? The chemistry has been good, and you’re starting to see guys’ confidence go up because of that.”

An ankle sprain ruled out Houston’s leading scorer Kevin Durant for the second time in the series.

The Rockets also host game four on Sunday and must win to prevent the Lakers earning a sweep of the series and booking their place in the Western Conference semi-finals.

Conference rivals San Antonio lead the Portland Trail Blazers 2-1 after fighting back to claim a 120-108 win on the road.

Stephon Castle scored 33 points for the Spurs while rookie reserve Dylan Harper added career bests of 27 points and 10 rebounds.

Victor Wembanyama was on the Spurs bench but could not play as this season’s defensive player of the year remained in concussion protocol after suffering a head injury in game two on Tuesday.

The Boston Celtics took a 2-1 lead over Eastern Conference rivals Philadelphia as they claimed a 108-100 win at the 76ers.

Jayson Tatum scored 11 of his 25 points in the fourth quarter while Jaylen Brown also scored 25 points for Boston.
