The prelims, which took place on Sept. 14, started with 16 teams hoping to snag one of four qualifier slots. That number was cut in half on Day 1, and the eight teams left standing — SK, NRG, Liquid, Echo Fox, OpTic Gaming, Renegades, Immortals, and TSM — faced off on Sept. 15.

First up was Immortals versus Team SoloMid, with Immortals sweeping TSM 2-0 with a narrow 16-14 victory on Mirage followed by 16-10 on Cobble. Immortals's Lucas "lucas1" Teles dominated the series with 52 kills to 34 deaths and 97.7 ADR.

NRG had the poor luck to go up against SK Gaming in their Day 2 match. With the return of Fernando "fer" Alvarenga to active duty, the ESL One: Cologne 2016 champions were eager to stretch their legs. They won the match 2-0, taking Dust 2 at a handy 16-8, with both Marcelo "coldzera" David and fer boasting 101.2 ADR on the map.

Overpass went to SK at an even handier 16-7. On the second map, the Brazilians dominated on CT with 14 rounds to NRG's one. NRG held off defeat on the switch-over for several rounds, walking away in defeat but not in shame.

SK's ESL One Cologne 2016 rivals, Team Liquid, went up against Echo Fox in the third match of the day. The first half of Mirage was pretty even at 8-7 in Liquid's favor, but the house Spencer "Hiko" Martin built pulled ahead after the half, winning Game 1 16-11.

However, it was Echo Fox that dominated Nuke, taking 11 rounds on T to Liquid's 4 and closing out the second half 16-9 on CT.

The third game saw a wild comeback from Echo Fox. Liquid gained a massive 12-4 lead over Echo Fox, but Fox came back swinging, able to overtake Liquid with a 16-13 final score. Shahzeb "ShahZaM" Khan rocked a notable 1.93 KDR. With the Game 3 win, Fox took the match and advanced to ELEAGUE Season 2.

The final match of the day saw OpTic Gaming take an impressive 13-2 lead over Renegades in the first half of Cache. Renegades nearly came back in the second half, but OpTic managed to secure the three rounds needed to win the map 16-13.

Map 2 was Dust 2, with Renegades taking a strong 10-5 lead at the half, but things fell apart for the Australians on their CT-side. They could only muster three rounds, and OpTic pulled off the comeback to take the map 16-13 and qualify for ELEAGUE 2-0 over Renegades.

The groups for ELEAGUE Season 2 have yet to be announced, but the league will kick off on Oct. 21, and will end on Dec. 3.
