After losing their playoff opener, the Los Angeles Thieves reeled off five straight wins, culminating in a victorious battle over OpTic Texas on Sunday in the grand final of the Call of Duty League Stage 3 Major in Atlanta.

Los Angeles won the best-of-seven final 4-3 to earn $150,000 and 100 CDL points. OpTic Texas, which had advanced to the final with a 3-2 win over Toronto KOI earlier Sunday in the upper-bracket final, collected $90,000 and 75 points.

The Thieves' path began with a 3-2 setback to FaZe Vegas in the upper-bracket quarterfinals. That dropped them to the first round of the lower bracket, where they dispatched GS Minnesota 3-1. A 3-0 sweep of the Riyadh Falcons in the quarterfinals matched them up with FaZe Vegas in Sunday's lower-bracket semifinal, which Los Angeles won 3-1.

Texas surged ahead with wins on Den Hardpoint (250-242) and Scar Search and Destroy (6-4), only for the Thieves to win the final two maps, 5-4 on Scar Overload and 6-2 on Den Search and Destroy.

OpTic Texas defeated Toronto KOI 3-2 in the upper-bracket final earlier on Sunday. Texas won 250-152 on Gridlock Hardpoint, then Toronto drew even with a 6-1 win on Raid Search and Destroy.

The back-and-forth continued, as OpTic won 5-4on Exposure Overload, then KOI triumphed 250-212 on Scar Hardpoint. Texas won 6-2 on Scar Search and Destroy to capture the match.

OpTic's Otell was Match MVP with 83 kills and a plus-4 K-D differential. Tobias 'CleanX' Jonsson of Denmark paced Toronto with a match-high 106 kills and a plus-18 K-D differential.

Toronto KOI dropped down to the lower-bracket final, where they were swept 3-0 by the Thieves. Los Angeles won 250-93 on Sake Hardpoint, 6-4 on Den Search and Destroy and 4-0 on Den Overload.
