Despite playing through a calf strain, Jamal Murray hit a pull-up 14-footer with 3.6 seconds remaining, and the Denver Nuggets beat the Los Angeles Lakers 108-106 on Monday for a 4-1 series win.

Murray, who also hit a buzzer-beater to win Game 2, was a game-time decision due to his calf injury but scored 12 of his 32 points in a fourth quarter in which the teams repeatedly traded leads.

LeBron James hit a pair of free throws to tie the game with 26 seconds left to give the Lakers hope, but Murray drove to his left with help from a high ball screen and pulled up for the go-ahead jumper over Austin Reaves.

Without any timeouts to advance the ball, the Lakers managed only a desperation heave from Taurean Prince at the buzzer which never had a chance.

Much like last year, when the Nuggets swept the Lakers in the Western Conference finals, Denver’s late-game execution proved to be the difference.

Nikola Jokić finished with 25 points, 20 rebounds and nine assists, while Michael Porter Jr. concluded his impressive series with a 26-point performance.

James led the Lakers with 30 points and 11 assists. Anthony Davis had 17 points and 15 rebounds but was not involved much in the offence late while playing through a shoulder injury.

The Nuggets will continue their championship defence with a second-round series against the Minnesota Timberwolves, who advanced Sunday by completing a sweep of the Phoenix Suns.

Denver eliminated Minnesota in the first round of last year’s playoffs with a five-game series win.

Thunder complete sweep of Pelicans

Shai Gilgeous-Alexander and Jalen Williams each scored 24 points to lead the Oklahoma City Thunder to a 97-89 win over the New Orleans Pelicans and secure a four-game series sweep.

The youngest team ever to secure a conference’s No. 1 seed, the Thunder answered questions about play-off inexperience by easily securing their place in the second round, outscoring New Orleans by an average of 15.8 points per game.

Oklahoma City trailed 71-70 to start the fourth quarter but held the Pelicans to 18 points in the final frame.

Williams scored 11 of his points in the fourth quarter, including his own 8-0 run that put the Thunder up 93-82 with 3:08 remaining.

The Pelicans played the series without Zion Williamson due to a hamstring strain, with Brandon Ingram and CJ McCollum failing to rise to the challenge.

Ingram shot under 35 percent from the field during the series and was 2 of 14 in Game 4. McCollum had 20 points on 9-for-16 shooting Monday but was just 7 of 29 from 3-point range in the series.

Celtics rout Heat for 3-1 series lead

Derrick White scored 38 points, and the Boston Celtics overcame an injury to Kristaps Porzingis to beat the Miami Heat 102-88 for a 3-1 series lead.

Porzingis exited with 2:27 remaining in the second quarter with right calf tightness and did not return. Al Horford started the second half in Porzingis’ place.

White, who is better known for his defensive contributions, went 8 of 15 from 3-point range en route to his 38 points, a career high for both the regular season and post-season.

Bam Adebayo led the way for the Heat with 25 points, 17 rebounds and five assists.
