Denver, CO (Sports Network) - Peyton Manning threw for 338 yards and three touchdowns in a near-flawless performance, and the Denver Broncos erupted for 27 unanswered points in the second half to record a 37-6 rout over the Oakland Raiders at Sports Authority Field at Mile High.

Manning completed a crisp 30-of-38 passes in the most impressive outing of the offseason acquisition's four-game tenure with the Broncos, while Willis McGahee rushed for 112 yards and a touchdown to help Denver (2-2) halt a two-game losing streak.

Demaryius Thomas added 103 receiving yards on five catches and Eric Decker had seven catches for 79 yards and a touchdown for the Broncos, who piled up 503 total yards and also ended a string of four straight Raider victories in Denver in the series.

Oakland (1-3), which was coming off a 34-31 come-from-behind triumph over Pittsburgh last week for former Denver defensive coordinator Dennis Allen's first win as head coach, managed just 237 total yards and 12 first downs, with star running back Darren McFadden held to 34 yards on 13 carries by a swarming Broncos' stop unit.

Carson Palmer finished with 202 yards on 19-of-34 passing for the Raiders in their final contest before a Week 5 bye.
