The Toronto Ultra and Seattle Surge opened Call of Duty League Stage 4, Week 3 with victories on Thursday in the Los Angeles Thieves home series.

The Ultra swept the Los Angeles Guerrillas while the Surge outlasted OpTic Chicago in a back-and-forth affair.

The Ultra made quick work of the Guerrillas, winning 250-136 on Garrison Hardpoint, 6-3 on Express Search and Destroy and capping the victory 3-1 on Raid Control.

The Surge, however, had to work for their victory. Seattle opened with a 250-232 win on Raid Hardpoint. OpTic Chicago responded with a 6-3 win on Moscow Search and Destroy. Surge went back with a 3-1 decision on Checkmate Control. But OpTic took Checkmate Hardpoint 250-227 to force a fifth map. The Surge then clinched it 6-4 on Raid Search and Destroy.

It snapped a 10-match losing streak for Seattle, which hadn't won since April 8.
