With one round left, three teams find themselves knotted atop the standings following Sunday's action in the ESL Pro League Season 12: North America Event.

FURIA Esports dropped their first match of the season with a 2-0 loss to 100 Thieves. That loss, coupled with wins from Evil Geniuses and Team Liquid, leave FURIA, EG and Liquid tied at 5-1 with one match left for each before the playoffs.

Team Liquid dispatched Gen.G Esports 2-0 on Sunday. Evil Geniuses scored a 2-1 win over winless Triumph, and Chaos Esports Club took out Cloud9 2-0.

100 Thieves (3-3) stunned FURIA with a 16-12 win on Train, then cruised to a 16-8 win on Nuke. Aaron "AZR" Ward powered 100 Thieves with 46 kills and a plus-14 kill-to-death differential.

Team Liquid won 16-10 on Nuke in its opener, then finished off Gen.G (2-4) with a 19-17 overtime victory on Mirage. Keith "NAF" Markovic led Liquid with 46 kills and had a plus-8 differential.

Chaos Esports Club (3-3) had no issues whatsoever with Cloud9 (1-5), as they ran away with wins of 16-3 and 16-5 on Nuke and Overpass, respectively. Edgar "MarKE" Maldonado had 39 kills, and posted the best differential in the league on Sunday with a plus-22 margin.

Evil Geniuses needed three maps to get by Triumph (0-6). After winning 16-9 on Inferno, EG suffered a 16-12 loss on Nuke before rebounding to win 16-10 on Train. Vincent "Brehze" Cayonte posted match highs of 66 kills and a plus-18 differential.

The top two teams in the standings of the $225,000 Counter-Strike: Global Offensive tournament will advance to the upper bracket of the double-elimination playoffs. The third- and fourth-place sides will move on to the lower bracket of the playoffs.

All matches except for the final are best-of-three. The Sept. 27 championship match will be best-of-five, with the team emerging from the upper bracket starting with a one-map lead.

Week 4 begins Tuesday with four matches: Evil Geniuses vs. Team Liquid, Gen.G Esports face Cloud9, FURIA Esports battle Chaos Esports Club, and 100 Thieves take on Triumph. It will be the final round of group play.
