The Los Angeles Clippers completed a Game 6 comeback to beat the Utah Jazz 131-119, winning the series 4-2.
The Clippers are headed to their first Western Conference finals in franchise history.
The Clippers were led in scoring by Terance Mann, who finished with 39 points while hitting 7 of 10 from three.
"I just had to lock in and do what I had to do," said Mann. "They were leaving me open."
The team trailed by 22 at halftime and completed the largest halftime comeback in a series-clinching game in league history. They outscored the Jazz 75-40 to end the game.
"This was my first time experiencing a crowd like this," said Paul George, who had 28 points, nine rebounds, and seven assists. "It was just a special night. You felt it, the cheers, the excitement. You felt the monkey off of the Clippers' back in terms of getting out of the second round."
Patrick Beverley put the achievement in perspective.
"I was here when we were an eighth seed, celebrating just to get into the playoffs. To finish a game like this, to make history, it's special because [I've poured] blood, sweat and tears into this s---. Injuries, friends getting traded ... to be the last man standing and write history is special."
