Team Vitality, The MongolZ and Team Spirit finished off sweeps in their respective upper-bracket quarterfinals to open Group B play of the BLAST Open Spring on Thursday in Copenhagen, Denmark.

PARAVISION also won its opening match to remain in the winner's bracket. 9z Team, MOUZ, Team Liquid and Ninjas in Pyjamas each lost their opening matches and will face elimination on Saturday.

The 16 teams in the $400,000 Counter-Strike: Global Offensive event were split into two groups of eight that will contest a pair of double-elimination brackets. The top three finishers in each bracket will advance to the six-team playoffs. All matches will be best-of-three until the best-of-five grand final on March 29.

The winning team will earn $150,000 along with three BLAST Frequent Flyer tokens.
