Team Liquid defeated Clutch Gaming in the 2019 LCS Summer Semifinals and will move on to the Finals to face Cloud9. Both summer finalists will qualify for the 2019 League of Legends World Championship — the winner through auto-qualification and the runner-up through circuit points.
Team Liquid entered the Semifinals with the most circuit points in the LCS due to the team's 2019 Spring Split Championship and 1st seed qualification in the 2019 LCS Summer Playoffs. Since TSM was eliminated by Clutch Gaming in the Quarterfinals, Cloud9 entered the Semifinals with the second most circuit points due to the team's 3rd place finish in the Spring Playoffs and it 2nd seed qualification in the Summer Playoffs.
If Team Liquid manages to make history and win a fourth consecutive split, the reigning champion of North America will qualify for Worlds as the 1st seed. If Cloud9 is able to win its first domestic title in five years, then C9 will be the primary representative of the LCS at Worlds with Team Liquid qualifying on circuit points.
Either way, Team Liquid and Cloud9 will join 1st seed from the LEC G2 Esports and 1st seed from the LCK Griffin as the team's locked in for Worlds 2019.
With the Finals set, the four teams in the 2019 LCS Regional Finals have also been confirmed. TSM will serve as the final boss at the end of the regional gauntlet, and FlyQuest will be starting at the bottom rung of the tournament after following up at 4th place spring finish with a 9th place finish in summer. Clutch Gaming and Counter Logic Gaming will occupy the two middle slots in the Regional Finals, with the higher seeded team being decided by CG and CLG's 3rd place match in Detroit.
