LeBron James' double-double fired the Los Angeles Lakers back to winning ways, while James Harden stepped up to rally the Kyrie Irving-less Brooklyn Nets past the high-flying Phoenix Suns.

James put up 30 points, 13 rebounds and seven assists as the reigning NBA champions leaned on their defense in the 112-104 victory over the last-placed Minnesota Timberwolves.

Without the injured Anthony Davis, Dennis Schroder played the supporting role for James, posting 24 points, while the Lakers battled to claim eight steals and seven blocks in a closely fought contest.

After taking a two-point lead into the fourth quarter at Target Center, the road side pulled away in the closing stages to improve to 22-7 in second place in the Western Conference.

Harden pulled out the stops with a double-double to lead the Nets to a sensational 128-124 comeback win against the Suns, despite playing without Irving after the star guard felt tightness in his lower back.

Nets coach Steve Nash revealed Irving received treatment at half-time of Brooklyn's win against the Sacramento Kings on Monday but expects the six-time All-Star to only be sidelined in the short term.

The Nets surged, scoring 40 fourth-quarter points to turn around a 24-point deficit, with Harden (38 points, 11 assists and seven rebounds) backed up by Joe Harris (22 points) as they halted the Suns' six-game winning streak.

Jokic burns Celtics but Nuggets fall short, Zion on target for Pelicans

Nikola Jokic lit up the Boston Celtics, scoring 43 points, but the Denver Nuggets could still not make triple-digits as their three-game winning stretch was ended in a 112-99 loss.

Zion Williamson shot an efficient 31 points, sinking 13 of his 16 field-goal efforts and going four-of-four from the free-throw line, as the New Orleans Pelicans snapped a three-match losing run with a 144-113 win over the Memphis Grizzlies.

Meanwhile, Damian Lillard’s 31-point, 10-assist double-double led the Portland Trail Blazers past the Oklahoma City Thunder in a 115-104 win, while centre Enes Kanter pulled down 21 rebounds.

Bazley struggles to take his chances

The Thunder never recovered against the Blazers after falling 34-21 behind in the first quarter and forward Darius Bazley was one player that could not find his range.

Bazley shot four from 16 from the field for 14 points during his 36 minutes on court, only dropping one his seven efforts from three-point range.

Giannis powers up but the Raps edge the Bucks

Giannis Antetokounmpo proved unplayable at times, scoring 34 points in the Milwaukee Bucks' 124-113 loss against the Toronto Raptors, as he ghosted past three defenders for one of his buckets.
