The Los Angeles Lakers issued a reminder of their quality as the reigning NBA champions outclassed the Phoenix Suns 109-95 to seize control in the Western Conference first-round series.

Injuries crippled the Lakers for most of the season as they slipped down to the play-in tournament and the seventh seed, but Anthony Davis and LeBron James starred at Staples Center on Thursday.

Davis posted a dominant double-double of 34 points and 11 rebounds and James put up 21 points as the Lakers claimed a 2-1 series lead following back-to-back victories against the second seeds in the playoffs.

Giannis Antetokounmpo and the Milwaukee Bucks, meanwhile, are poised to sweep the Miami Heat after easing to a 113-84 win.

Bucks superstar Antetokounmpo posted 17 points and 17 rebounds to go with five assists, while Khris Middleton (team-high 22 points) and Jrue Holiday (19 points and 12 assists) contributed en route to a commanding 3-0 series lead.

The Bucks – who are eyeing their first championship since 1971 – can seal a sweep on Saturday.

Jokic inspires Nuggets

MVP frontrunner Nikola Jokic was at his brilliant best as the Denver Nuggets outlasted the Portland Trail Blazers 120-115 on the road. Jokic scored 36 points and collected 10 rebounds to guide the third-seeded Nuggets to a 2-1 series lead in the west. Damian Lillard's 37 points and Jusuf Nurkic's 13-point, 13-rebound double-double were not enough for the Trail Blazers.

Milwaukee's Holiday produced another impressive display against the Heat following his 15-assist performance in Game 2 as he became the first Bucks player with back-to-back 10-plus assist games in the playoffs since Sam Cassell in 2001. The 2013 All-Star was plus-37 in Game 2 and plus-42 in Game 3. According to Stats Perform, Holiday became the first NBA player to have a plus-minus of plus-37 or better in back-to-back games since Kobe Bryant in 2003.

Miami's shooting woes

The less said about the Heat's shooting on Thursday, the better. As a team, Miami were just 37.6 per cent from the field – making 32 of their 85 shots. From three-point range, the Heat were only 28.1 per cent (nine of 32). Goran Dragic (eight points) finished three-for-14 shooting in 29 minutes, while Duncan Robinson (two points) was one of six from the field, having missed all four three-pointers.

Chris Paul and Devin Booker were not at their usual high standards for the Suns. Paul, who hurt his shoulder in Game 2, was three-for-eight shooting for just seven points. All-Star team-mate Booker had 19 points, but it was on six-for-19 shooting from the field in 41 minutes. He only made one of four attempts from beyond the arc.

Rivers lights up fourth quarter

Denver's Austin Rivers was in red-hot form in the final period against the Blazers. Rivers scored 16 of his 21 points in the fourth to help the Nuggets to victory.
