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.

On Saturday, Secret posted wins in 28 and 19 minutes, respectively over Na'Vi, while Unique outlasted Vikin.gg with wins in 26 and 63 minutes sandwiched around a default.

Alliance made short work of previously undefeated VP.Prodigy, registering wins in 35 and 27 minutes, respectively.

Family Team registered victories in 37 and 29 minutes over Gambit, while NiP took care of OG with wins in 28 and 30 minutes.

FlyToMoon finished the day with victories over Winstrike in 34 and 30 minutes.
