Cloud9 and G2 Esports each completed a sweep on Wednesday in the upper-bracket quarterfinals of Group D at the ESL Pro League Season 18 event in Malta.

Cloud9 blanked Eternal Fire 2-0, while G2 downed Lynn Vision Gaming 2-0.

The other Group D winners on Wednesday were Complexity Gaming, who beat 9INE 2-1, and Virtus.pro, who edged Team Liquid 2-1.

Wednesday's four losers were relegated to the mid bracket.

The $850,000 Counter-Strike: Global Offensive event features 32 teams broken up into four groups of eight. Group-stage winners advance to the quarterfinals; runners-up advance to the Round of 12 as the high seeds; third-place teams advance to the Round of 16 as the high seeds; and fourth-place teams advance to the Round of 16 as the low seeds.

The group stage is triple elimination with upper, middle and lower brackets. All matches are best-of-three until the grand final, which is best-of-five.

The tournament runs through Oct. 1. The winner earns $200,000 and qualifies for the 2024 IEM Katowice event and the 2023 BLAST World Final.

On Wednesday, Cloud9 won 16-11 on Vertigo and 16-12 on Overpass. Russian Sergey "Ax1Le" Rykhtorov led the winning side with a match-high 52 kills to go along with a plus-19 kills-deaths differential. All five of Eternal Fire's members had negative K-D ratios.

G2 Esports opened with a 19-16 overtime victory on Anubis before cruising to a 16-5 triumph on Inferno. G2's Rasmus "HooXi" Nielsen of Denmark led all players with 49 kills and a plus-14 K-D differential.

After Complexity took Anubis 16-11, 9INE prevailed 16-12 on Vertigo to level the match. Complexity clinched by prevailing 16-13 on Ancient, getting a huge boost from Norwegian Hakon "hallzerk" Fjaerli, who racked up 75 kills for the match.

Dzhami "Jame" Ali posted 67 kills and a plus-22 K-D differential for the all-Russian Virtus.pro squad, which sandwiched wins on Inferno (16-11) and Anubis (16-14) around a 19-17 overtime setback on Mirage to get past Liquid.
