The Cleveland Cavaliers beat the Chicago Bulls 94-73 on Thursday to clinch their Eastern Conference semi-final series in six games.
This will be the first time the Cavaliers have advanced to the conference finals since 2009.
It also marks the fifth straight conference finals appearance for LeBron James.
James struggled to score in Game six, netting only 15 points for Cleveland.
He shot 7 of 23 from the field and missed all four 3-point attempts in the game.
After missing the last two games with a hamstring injury, Pau Gasol was back in the Chicago line-up and he helped the Bulls get off to a good start.
The Spaniard finished with eight points and five rebounds in 24 minutes.
The 34-year-old said he had tried his best to improve and to play in the game.
"I mean, they deserved to move on. We were banged up, unfortunately I had to miss the two previous games and I couldn't help my team, you know, and I tried my best to heal or improve to the point that I could play tonight and be out there but you know it wasn't enough."
The Cavaliers will next face the winner of the series between Washington and Atlanta.
