Nigma swept Team Unique (1-3) in Group A action, and VP.Prodigy outlasted FlyToMoon (2-2) by a 2-1 margin in Group B. They were left as the only unbeaten teams after Vikin.gg (3-1) were swept by Team Secret (3-1) in a battle of Group A contenders.

ESL One Birmingham, a $300,000 Dota 2 major, had been scheduled for this week in Birmingham, England, before plans were changed due to the coronavirus pandemic. The tournament was separated into four online regional competitions: Europe/Commonwealth of Independent States, North America/South America, China and Southeast Asia.

The $40,000, six-team Southeast Asia event began last week and runs through Sunday. The other three divisions -- Europe/CIS (16 teams, $200,000), the Americas (six teams, $40,000) and China (eight teams, $55,000) -- will conclude June 7.

The Europe/CIS event features two eight-team groups for round-robin play in best-of-three matches. The top two teams in each group advance to the upper bracket of the double-elimination playoffs, and the third- and fourth-place teams earn spots in the lower bracket. The bottom four teams in each group are eliminated.

The playoffs are set to start Tuesday. All playoff matches will be best-of-three until the best-of-five final.

Nigma dispatched Unique in a total of 65 minutes, comfortably the quickest match of the day.

VP.Prodigy required more work. After they took the first game in 41 minutes, FlyToMoon responded with a 53-minute victory. VP.Prodigy recovered to win the final game in 30 minutes and clinch the match.

Secret took down Viking in a total of 78 minutes, while Na'Vi sandwiched wins of 26 and 40 minutes around a 36-minute loss to Family.

OG and HellRaisers split a pair of 34-minute games -- the first going to OG -- before HellRaisers captured a back-and-forth, 49-minute game in the decider.

Cyber Legacy took the first game from NiP in 42 minutes, dropped a 36-minute game and then won a 35-minute game to close out the victory.
