When was the last time the chargers beat the ravens?

On December 5, 2010, the Raiders defeated the Chargers, 28-13, at San Diego. It gave Oakland a rare season's sweep over their longtime rivals in Southern California.

Earlier, Chargers hadn't lost a regular-season game to the Oakland Raiders since September 28, 2003 at Oakland -- a streak of 13 games. But on October 10, 2010, the Raiders upset the Chargers, 35-27, with two touchdowns in the final four minutes.
