Six teams. Three days. One trophy. The BLAST Open Spring 2026 playoffs kick off on Friday, March 27 at Rotterdam’s Ahoy Arena, and the bracket is loaded with narratives that the group stage spent a full week building.

Vitality and NaVi earned direct semifinal byes after topping their respective groups without a single series loss. The remaining four teams enter the quarterfinals on Friday, where single elimination means one bad map veto can end your tournament. Every match is Bo3 except the Grand Final, which is a Bo5 scheduled for Sunday, March 29 at 12:30 CEST.

Here is every matchup, the context behind it, and where the smart money should be looking.

Quarterfinal #1: Aurora vs. The MongolZ (March 27, 15:00 CET)

Aurora are the higher seed here after finishing second in Group A behind NaVi. The all-Turkish core of XANTARES, woxic, and MAJ3R beat FaZe in the opening round and only dropped maps to NaVi across the entire group stage. On paper, this should be comfortable.

The MongolZ tell a different story. They scraped into the bracket from the lowest possible position, surviving through the Group B lower bracket after a 0-2 loss to Vitality in the upper round. But they peaked exactly when it mattered: mzinho put on a masterclass against Spirit in the final elimination match, winning the series 2-0 and knocking a top-5 team out of the tournament entirely. Spirit’s exit was the biggest shock of the group stage.

Aurora and The MongolZ have become one of CS2’s most recurring playoff matchups, with multiple elimination-stage meetings across 2025 alone, including a memorable quarterfinal at BLAST Bounty Fall where The MongolZ completed an infamous 0-11 to 16-13 comeback on Mirage. Aurora are favored, but The MongolZ play with zero fear on LAN and their confidence is sky-high after eliminating Spirit. Do not sleep on this one.

Quarterfinal #2: PARIVISION vs. Falcons (March 27, 18:30 CET)

This is the headline match of the opening day and the result of the BLAST Open Rotterdam bracket that everyone circled the moment groups ended. It is a direct rematch of the PGL Cluj-Napoca quarterfinal, which Jame‘s PARIVISION won 2-1 over Falcons just last month. That result still stings in the Falcons camp.

PARIVISION enter riding enormous momentum. They won BLAST Bounty Winter 2026 in January, reached the Cluj-Napoca Grand Final in February (losing only to Vitality), and now have a roster that is genuinely dangerous at every position. Jame remains the tactical anchor and AWP threat, BELCHONOKK provides firepower, and zweih, poached from Spirit at the end of 2025, has elevated the ceiling of this team dramatically. Their group stage run in Rotterdam was clean until Vitality swept them 2-0 in the upper bracket final. That loss is the only blemish.

Falcons had a rough start. Rifler kyousuke missed the opening match against NRG due to visa issues, forcing the team to play with academy stand-in NucleonZ. Even after kyousuke joined, Falcons lost to NaVi in the upper bracket and had to grind through the lower bracket, beating TYLOO 2-1 and outlasting FURIA 2-1 to survive. They are battle-tested but bruised. Coach zonic has been publicly vocal about demanding more from his players heading into the playoffs.

The question is whether Falcons can flip the Cluj-Napoca script. PARIVISION have the form, the confidence, and the recent head-to-head. Falcons have the individual talent ceiling with karrigan calling and a stacked rifle core. This match could go the distance.

Semifinal #1: Vitality vs. QF1 Winner (March 28, 15:00 CET)

Vitality are the world #1 and it is not particularly close. apEX, ZywOo, ropz, flameZ, and mezii went through the group stage without dropping a single map: three series, six maps, zero losses. They swept 9z, The MongolZ, and PARIVISION in succession. ZywOo produced a ridiculous 1v5 clutch against PARIVISION in the upper bracket final that essentially sealed the semifinal bye.

The reigning back-to-back Major champions have won PGL Cluj-Napoca 2026 and IEM Krakรณw 2026 already this year. They held a 30-match LAN win streak in 2025 that only broke mid-year. No team in the server looks as composed, as structured, or as individually lethal.

Whoever emerges from Aurora vs. The MongolZ faces a near-impossible task. Vitality are the clear tournament favorites and would need to collapse for this semifinal to be competitive.

Semifinal #2: NaVi vs. QF2 Winner (March 28, 18:30 CET)

NaVi arrive on the back of an ESL Pro League Season 23 title won just days before BLAST Open started. makazze earned his first MVP award at EPL, and the 19-year-old has looked like a different player since replacing jL in the lineup. Alongside Aleksib calling, w0nderful on the AWP, and b1t and iM providing consistent rifle support, this NaVi roster finally looks like it has an identity again.

In the group stage, NaVi dropped maps to both B8 and Falcons in the opening rounds but cleaned up with a convincing 2-0 over Aurora in the upper bracket final. They are not flawless, but they are dangerous. B1ad3 has this team peaking at the right time, and the Major qualification implications add extra urgency.

If PARIVISION win the quarterfinal, NaVi vs. PARIVISION would be the most anticipated semifinal. B1ad3 has publicly stated he believes PARIVISION have exploitable weaknesses. Jame would love nothing more than to prove him wrong on the Rotterdam stage.

The Bigger Picture

This is not just about the $400,000 prize pool or even the trophy. BLAST Open Spring results feed directly into the Valve Ranking System, and the April 6 VRS deadline for IEM Cologne Major 2026 invites is ten days away. For teams like Falcons, The MongolZ, and Aurora, a deep run in Rotterdam could be the difference between a Major invite and an open qualifier. For Spirit and FaZe, who both crashed out in groups, the damage is already done.

Vitality and NaVi look destined for a Grand Final collision. But the quarterfinals on Friday might produce the best CS2 we see all weekend. Tune in Friday at 15:00 CET on Twitch and YouTube.
