GLENDALE, Ariz. (AP) — Patrick Mahomes saw his first extended action of the preseason, throwing for 105 yards and a touchdown, and the Kansas City Chiefs beat the Arizona Cardinals 38-10 on Saturday night in the second preseason game for both teams. The reigning MVP for the defending Super Bowl champs completed 10 of 15 passes, playing the entire first quarter. The Chiefs’ first-team offense wasn’t very crisp during its first two drives, fighting through a few dropped passes and penalties. But Kansas City found the end zone on its third try when Mahomes rolled out to his right and hit Justin Watson for an 18-yard touchdown and a 7-0 lead.
