Dallas Fuel completed an unbeaten playoff run with a 4-0 sweep of Team Liquid on Sunday in the grand final of the Overwatch Champions Series' North America Stage 3.

Team Liquid had blanked Spacestation Gaming 3-0 earlier in the lower-bracket final to earn a rematch with Dallas Fuel, which had defeated Spacestation 3-0 on Friday and Team Liquid 3-1 on Saturday.

The tournament's regular season began Oct. 10 with six teams competing in a round-robin format. All matches were first-to-three. The top four teams advanced to the double-elimination regional playoffs, which ran through Sunday. All matches in the $75,000 tournament were first-to-three except for the grand final, which was first-to-four.

The top three teams -- Dallas Fuel, Team Liquid and Spacestation Gaming -- earned berths in the Overwatch Champions Series' World Finals, scheduled for Dec. 2-6 in Guangzhou, China.

Team Liquid and Dallas Fuel each finished 4-1 in the regular-season standings, with Liquid winning their head-to-head matchup 3-2 on Oct. 18. Spacestation, which opened the regular season with a 3-1 win over Liquid on Oct. 10, finished 3-2 and placed third.

On Sunday, Team Liquid swept Spacestation by winning 2-1 on Ilios Control, 3-1 on Suravasa Flashpoint and 5-4 on Eichenwalde Hybrid in the lower-bracket final.

Dallas, however, did not lose a map in the first-to-four grand final, defeating Team Liquid 2-0 on Busan Control, 3-2 on Route 66 Escort, 2-1 on Paraiso Hybrid and 117.07 meters to 51.56 meters on Runasapi Push.
