G2 Esports and Team Spirit advanced to the upper-bracket final of Group A on Sunday at the Intel Extreme Masters Krakow tournament in Poland.

G2 fought past FUT Esports 2-1, and Team Spirit beat Natus Vincere 2-0.

The lower bracket of Group A kicked off with FURIA and Astralis advancing by 2-1 decisions, while in Group B, MOUZ blanked NRG 2-0 and Aurora Gaming outlasted Team Falcons 2-1 in their openers.

The $1 million Counter-Strike: Global Offensive tournament started with 24 teams and is currently in a 16-team double-elimination group stage involving best-of-three matches. The group winners earn spots in the playoff semifinals, the group runners-up head to the playoff quarterfinals as high seeds and the third-place teams go to the playoff quarterfinals as low seeds.

The playoffs will consist of a single-elimination bracket of best-of-three matches until the grand final on Feb. 8, which will be best-of-five. The championship team will receive $400,000, and the runner-up will get $180,000.
