BALTIMORE (AP) — Patrick Mahomes put on a scintillating show while outperforming Lamar Jackson, and the Kansas City Chiefs deftly played the role of defending Super Bowl champions in a 34-20 thumping of the Baltimore Ravens. Just about everything Mahomes did worked against an overmatched Baltimore defense that had allowed only two touchdowns in its first two games. Mahomes threw four touchdown passes to help the Chiefs emphatically ended the Ravens’ 14-game regular season winning streak while extending their own run to 12 games, including playoffs. Jackson is 21-4 as the Ravens' starting quarterback, with three of those losses to Mahomes and the Chiefs.
