Dallas Fuel completed their perfect run through the Overwatch Champions Series' North America Stage 1, taking down Spacestation Gaming 4-1 in the grand final on Sunday.

The Fuel beat Spacestation for the second straight day after prevailing 3-1 in the upper-bracket final on Saturday. Spacestation recovered, sweeping Team Liquid 3-0 earlier in the day Sunday in the lower-bracket final.

Dallas took home $30,000 while Spacestation settled for the runner-up prize of $15,000. But both teams will receive berths in the OCS Champions Clash, scheduled for May 22-24 in Tokyo.

The Overwatch 2 online competition, with a prize pool of $75,000, began with six teams playing a regular season with a round-robin format.

The top four teams advanced to the regional playoffs, and all sealed berths in North America Stage 2. All playoff matches were first-to-three except for the grand final, which was first-to-four.

On Sunday, Spacestation barely let Team Liquid on the scoreboard -- taking Busan Control 2-0, Blizzard World Hybrid 3-1 and Aatlis Flashpoint 3-0.

Then they ran into a Dallas Fuel team that went 5-0 in the regular season, dealing Spacestation their only loss in the early phase.

The Fuel opened the grand final by winning 2-0 on Busan Control and 2-1 on Midtown Hybrid. Spacestation answered with a 3-1 victory on Rialto Escort, but it wasn't enough to turn the tide. The Fuel took Suravasa Flashpoint 3-2 and clinched the championship with a 142.41m-7.48m blowout on Esperanca Push.
