G2 Esports won eight of the final nine rounds to complete a 2-1 series win over BIG on Wednesday and advance to the final of the DreamHack Masters Spring's European event.
G2 will oppose the lower-bracket winner for the championship on Sunday.
MAD Lions and Ninjas in Pyjamas stayed alive Wednesday with 2-1 lower-bracket wins over Fnatic and Team Vitality, respectively.
The DreamHack Masters Jonkoping, a $250,000 Counter-Strike: Global Offensive event, originally was scheduled to be contested with 16 teams from this week in Jonkoping, Sweden. However, the coronavirus pandemic forced the event to move to an online format featuring regional competitions for Europe, North America, Asia and Oceania.
The DreamHack Masters Spring - Europe bracket, with 16 teams split into four groups competing for $160,000, runs through Sunday. Each group played a round robin of best-of-three matches.
All playoff matches are best-of-three except for the grand final (where G2 will begin with a 1-0 advantage as the upper-bracket winner). The champion will receive $54,000 from the $160,000 prize pool, plus 400 Pro Tour points.
