ESL One Birmingham, a $300,000 Dota 2 major, had been scheduled for May 26-31 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 runs through Sunday. The other three divisions -- the Americas, Europe/CIS (16 teams, $200,000) and China (eight teams, $55,000) -- will conclude June 7.

The Americas event has the six teams playing a single round robin of best-of-three matches. The top two teams will advance to the upper bracket of the double-elimination playoffs, and the third- and fourth-place teams will earn spots in the lower bracket. The bottom two teams will be eliminated.

The playoffs are set to start June 4. All playoff matches will be best-of-three until the best-of-five final.

On Thursday, CR4ZY won the opening game in 50 minutes before Evil Geniuses leveled the score with a 26-minute win. CR4ZY captured the decisive third game in 37 minutes.

beastcoast produced a 28-minute win before business associates earned their own 28-minute victory. The last game resulted in a 35-minute beastcoast victory.

Three matches are scheduled for Friday. Evil Geniuses will oppose beastcoast, and Quincy Crew will take on Thunder Predator. Evil Geniuses will then complete a doubleheader, facing business associates in the makeup of a match that was postponed from Monday.
