OG, Team Spirit and Team Falcons separated themselves from the pack by going 3-0 through three matches at DreamLeague Season 27 on Friday.

Another nine teams sit right behind at 2-1, including BetBoom Team, which entered the day atop the group-stage standings but suffered its first loss, 2-0 to OG.

The $1 million Dota 2 event features 24 teams starting in a Swiss System group stage. All matches are best-of-three, with the top eight teams advancing to the double-elimination playoffs, which run from Dec. 17-21.

Playoff matches will all be best-of-three ahead of the best-of-five grand final.

The championship team will receive $200,000 in prize money and a $30,000 club reward. The runner-up side will get $125,000 and a $25,000 club reward.

On Friday, OG annihilated BetBoom Team in a quick 21 minutes on red and 33 minutes on green. Nikko 'Force' Bilocura of the Philippines posted an average kills-deaths-assists ratio of 8.5-2.5-10.5 to lead OG.
