South Korean team DRX were crowned League of Legends world champions on Saturday after scoring a surprise 3-2 victory over compatriots T1 in a thrilling final of the eSports tournament in San Francisco.

T1, the most successful team in eSports history, started as favorites and took the lead in the first round of the competition.

But DRX took command after many upsets, in particular thanks to 19-year-old Kim "Zeka" Geon-woo.

Their win, the team's first-ever, was highly anticipated for talented 26-year-old Kim "Deft" Hyuk-kyu, who started competing in 2014 but had only made it past the quarterfinals once, also in 2014.

No player so "old" had ever won the world championships until this year.

The final took place at the Chase Center in San Francisco, home to the Golden State Warriors NBA team, in front of some 16,000 spectators.

The League of Legends World Championship is considered one of the most prestigious eSports tournaments.
