The second-round victory was James' 162nd of his postseason career, passing Derek Fisher for first all-time.
Fisher had a less-heralded career than these stars, but he won five titles with the Lakers, also spending time with the Golden State Warriors, Oklahoma City Thunder, Utah Jazz and Dallas Mavericks over his 18 years in the NBA.
James was able to pass this mark in his 17th season while continuing an incredible career of playoff success.
The 35-year-old reached the postseason in each year from 2006-18 until last year's injury-filled campaign broke that streak. He had also reached the NBA Finals in eight straight seasons with the Cleveland Cavaliers and Miami Heat.
Though his teams have only won three NBA titles, LeBron has found unparalleled success during his playoff career.
James will try to add another championship to his resume this year with the Lakers, currently up 2-1 in the Western Conference Semifinals.
