M80 emerged with a 2-0 sweep of Fnatic on Wednesday at the ESL Pro League Season 20 in Saint Julian's, Malta, and the Group C upper-bracket semifinal qualified as one of the matches of the year.

M80 won the first map 37-34 on Anubis in a whopping eight overtimes. The second map also went to OT, with M80 prevailing 16-13 on Inferno.

The United States' Ethan "reck" Serrano compiled 75 kills and a plus-16 kill-death differential for M80. Denmark's Benjamin "blameF" Bremer logged 72 kills and a plus-14 K-D differential for Fnatic.

The result sends M80 to the Group C upper-bracket final on Saturday against Imperial Esports, who got past MOUZ 2-0 in another match that featured a pair of overtime maps. Imperial won 16-14 on Dust II, then 16-13 on Inferno.

Brazil's Lucas "decenty" Bacelar paced Imperial with 60 kills and a plus-28 K-D differential. Adam "torzsi" Torzsas produced 44 kills and a plus-4 K-D differential for MOUZ.

The group stage of the $750,000 Counter-Strike: Global Offensive event split 32 teams into four groups that are competing in triple-elimination brackets, with each match best-of-three. The top four teams from each group will move into the playoff bracket.

Group winners will advance straight into the playoff quarterfinals. Runners-up will advance to the Round of 12, third-place teams will move to the Round of 16 as high seeds and fourth-place teams will start in the Round of 16 as low seeds.

The single-elimination playoff bracket will feature best-of-three matches until the best-of-five grand final on Sept. 22.

The winner will receive $170,000 and will qualify for the first ESL Pro Tour Championship of 2025.
