100 Thieves and G2 Esports will open their Champions Shanghai playoff campaigns against each other in an all-Americas upper quarterfinal on October 8. The best-of-three begins at 11:00 AM CEST, with the winner moving to an upper semifinal. The loser drops to the lower bracket, so the series changes each team’s route but does not immediately eliminate either one.
The matchup is the only same-region pairing in the opening playoff round. That familiarity gives the series a different context from the international cross-region quarterfinals: both teams have competed in the Americas league, and each enters with a view of the other’s regional style. The event setting still changes the pressure because the match is part of a double-elimination bracket.
100 Thieves qualified with a 2-0 group-stage record. It entered the playoffs without needing a decider, which gives the roster a straightforward route into the bracket and a chance to carry its early-stage momentum forward. Group results do not guarantee a playoff win, but they provide a clean point of comparison for the teams’ recent form.
G2 needed a longer route. After losing to Paper Rex, it defeated Team Liquid in the decider to claim its playoff place. That path gave G2 a high-stakes elimination series before the bracket began. THESPIKE’s preview notes that the team looked more dangerous internationally than during its regional campaign, making this series a test of whether that event form continues.

Different group routes lead to the same bracket test
The records should be read with their match context. 100 Thieves finished its group stage 2-0, while G2 advanced through a sequence that included both a loss and a decider win. The first figure shows consistency across the group phase; the second shows that G2 handled an elimination match. Neither record alone decides the quarterfinal.
G2’s international performance has been a point of discussion because it has appeared more threatening on the global stage than in its regional matches. A familiar opponent may challenge that version of G2 in a new way. 100 Thieves has already seen the region’s tactical trends and can prepare specifically for the map pool selected by both sides.
The best-of-three format rewards preparation across the veto and adaptation between maps. A team can lose its preferred map and still recover on the next selection, but there is less room for a slow start than in a longer series. The event page confirms the format; exact map picks will only become known when the veto is completed.
The bracket creates pressure without making this a final-life match. The winner advances in the upper bracket and remains on the more direct route toward the upper final. The defeated team moves to the lower bracket, where it can still progress by winning subsequent matches. That distinction is important when describing the stakes: the quarterfinal is decisive for seeding path, not the end of the tournament.
Because the teams share a region, the contest can also test how much each has changed since its domestic preparation. Familiarity can help coaches identify patterns, but international opponents and the stage environment introduce new variables. Any tactical expectation beyond those points remains analysis, not confirmed match information.
The result changes the route, not the tournament status
100 Thieves will look to turn its unbeaten group record into a bracket win. G2 will try to extend the international form that carried it through the decider. Those are the narratives supported by the teams’ routes; neither should be treated as a prediction that one side is certain to win.
A 2-0 score would send the winner forward cleanly, while a three-map series would reveal how well each team can adjust after an opponent’s pick. In either case, the victor earns an upper semifinal place and the defeated side remains eligible to continue from the lower bracket. The next event page update will confirm the veto, map scores and advancement.
For viewers, the key comparison is the contrast in preparation paths: 100 Thieves arrived with two group wins, while G2 had to prove itself in a decider. The best-of-three will show whether the steadier record or the tougher elimination test translates better into the playoffs. Until the match starts, the exact tactical balance remains unknown.

The October 8 quarterfinal puts 100 Thieves’ 2-0 group record against G2’s decider-tested route. The winner reaches the upper semifinal; the loser drops to the lower bracket and can still continue in Champions.
