Los Angeles Lakers head coach Darvin Ham labelled LeBron James as "phenomenal" after scoring his 38,000th NBA career point, while the four-time MVP refused to discuss the milestone after another loss.

The Lakers slumped to a 19-24 record with Sunday's 113-112 loss to the Philadelphia 76ers where Russell Westbrook failed to get a clear shot or pass away on the final play.

Earlier, James made history in the first quarter by bringing up his 38,000th career point, joining only Kareem Abdul-Jabbar with that milestone.

James is on track to usurp Abdul-Jabbar's all-time NBA record of 38,387 points next month, although he would not be drawn on that after the game.

Instead, Ham offered praise for James, who finished with 35 points, eight rebounds and 10 assists.

"I thought Bron was phenomenal," Ham told reporters. "Really playing downhill. Playing the right way, running off the ball.

"Really finding guys as well. I thought he was really, really good."

James' performance was his 525th career 30-point game, while he is averaging 35.2 points, 10.0 rebounds and 8.5 assists across the past six games.

The 38-year-old was not in a reflective mood after the game, ignoring the 38,000-point milestone for concern about a disappointing loss.

"We got a stop, gave ourselves a chance to win the game and we didn't," James said about the final play.

"It's just frustrating, getting in those positions and not being able to come away with the victory."
