Los Angeles Lakers superstar LeBron James capped a championship-winning campaign with a fourth NBA Finals Most Valuable Player award.

James secured a fourth title and the Lakers claimed their first championship since 2010 after routing the Miami Heat 106-93 in Game 6 on Sunday.

The 35-year-old's 11th Finals triple-double of 28 points, 14 rebounds and 10 assists helped deliver a 17th championship to the Lakers at Walt Disney World Resort.

James is now the first player in NBA, MLB, NFL and NHL history to win the Finals MVP with three different teams, having also received the honour with the Cleveland Cavaliers and Miami Heat.

In his 17th season, James moved clear of Magic Johnson, Shaquille O'Neal and Tim Duncan with a fourth MVP – now only trailing Michael Jordan (six).

James also set another NBA playoff record, appearing in his 260th postseason game.

He moved into first place on the all-time list for playoff appearances, surpassing Derek Fisher.

Of the 4,489 players to have participated in an NBA regular-season contest, 63 per cent have not reached 260 games.
