The MongolZ cruised to a pair of 2-0 wins on Tuesday and captured first place in Group B at the Thunderpick World Championship in Berlin, sealing a berth in the quarterfinals.

After downing Cloud9, The MongolZ got past Fnatic, which had rallied past 9z Team 2-1 earlier in the day. In the Group B elimination match, Cloud9 ousted 9z Team 2-0.

The last playoff berth from the group will be determined on Friday when Cloud9 face off against Fnatic.

The $850,000 Counter-Strike: Global Offensive tournament began Monday and runs through Nov. 3.

A series of qualifiers in Europe, North America and South America set the 16-team field for the World Championship. The teams are divided into four groups of four teams. Each group plays a double-elimination tournament (best-of-three format), with the group winner advancing to the quarterfinals and the second- and third-place teams playing a decider match for the group’s other spot in the quarterfinals.

The single-elimination playoffs are best-of-three except for the final, which will be best-of-five. The championship team will take home $500,000, while the runner-up will get $150,000.

The MongolZ began play Tuesday with two tight map wins over Cloud9, 13-11 on Dust II and 13-11 on Ancient. Munkhbold “Senzu” Azbayar logged 40 kills and a plus-10 kill-death differential for the all-Mongolian winning side.
