The first three groups of GSL Code S were packed with upsets as former champions were eliminated left and right.
Group A: herO and DongRaeGu advance - VOD



Against herO, Rogue essentially got out-Zerged by his opponent's mass Gateway style, unable to overcome waves of Zealot-Stalker forces. As for his match against DRG, Rogue's first loss came due to some uncharacteristic errors as he allowed Baneling runbys to kill far too many of his Drones. However, the second win was more to DRG's credit, as he simply played a great all-around game and beat Rogue in the Muta wars. This is now the third time Rogue has been eliminated from the first round of Code S shortly after winning a major championship (the first time came after BlizzCon 2017 and the second time was after IEM Katowice 2020).
In the end, it was herO who advanced in first place, alongside DongRaeGu who earned his just reward of second place by upsetting the reigning champion.

Group B: Bunny and soO advance - VOD
Group B saw a former champion fall out as well in the form of

There was also a pleasant surprise in the form of

Group C: Zoun and Dark advance - VOD
Group C was the one that went relatively as expected, with




Dark took game one on Hardwire with one of his signature Nydus all-ins, but Zoun rallied to tie things on 2000 Atmospheres with a masterful late-game performance. Dark might be known as one of the best late-game players amongst Zergs, but he couldn't outtrade an exceedingly patient and efficient Zoun in the end. Zoun then closed out the 2-1 victory on Berlingrad, holding off an early game Ling-Ravager strike from Dark and counterattacking to force the GG.
While there's no real seeding advantage as players advance to the RO10, it will be a nice confidence boost for Zoun who once again showed his knack for beating Dark in important matches.
Unfortunately for Ryung, having to play his weak match-up of TvZ proved to be too big of a hurdle to overcome, and he went out in last place with losses to Dark and Armani. As for Armani, he put up a very respectable 4-5 map record despite being eliminated in third place, even managing to take a map off Dark in a straight-up macro game.
