The Dallas Fuel capped off a dominating performance in the West Region by sweeping the San Francisco Shock in the best-of-seven grand final of the Overwatch League Summer Showdown to win the tournament Sunday in Toronto.

After the Fuel handed the Shock their only loss during qualifying and swept them 3-0 in Saturday's upper-bracket final, San Francisco got one more shot at Dallas by winning the lower-bracket final earlier in the day Sunday. The Shock got past the host Toronto Defiant 3-1 to arrange the rematch.

But Dallas took care of business one final time, with four close map victories, to win the grand final and the $75,000 first prize at the $330,000 tournament.

The Fuel prevailed 2-1 on Lijiang Tower, 3-2 on Hollywood, 2-1 on Dorado and 1-0 on Colosseo.

In the lower-bracket final, the Defiant grabbed the early lead with a 2-0 win on Nepal. San Francisco bounced back with a 2-1 win on Hollywood and stayed in control from there, prevailing 3-2 on Dorado and 1-0 on Colosseo to advance.

Also Sunday, the Shanghai Dragons won the East Region grand final 4-2 over the Seoul Dynasty. The Dynasty reached the grand final by beating the Philadelphia Fusion 3-1 in the lower-bracket final.
