LeBron James scored 45 points to lead the Cleveland Cavaliers to a 105-101 win over the Indiana Pacers and into the second round of the NBA play-offs.
The 33-year-old, who has won three NBA Championships, faced elimination in the first round for the first time.
But he produced his third 40-point game of the series as Cleveland wrapped up the best-of-seven Eastern Conference series 4-3.
It earned them a second-round meeting with East top seeds Toronto Raptors.
The Pacers had ensured a tense deciding contest with a comprehensive 121-87 victory in game six on Friday.
But James made his first seven shots of the finale and finished the first half with 26 points, five assists and four rebounds.
He also became the first player to score 20 or more points 200 times in the play-offs and surpassed the record of Chicago Bulls great Scottie Pippen for most career post-season steals.
