The win was San Diego's first in 15 regular-season visits to Pittsburgh and snapped a four-game losing streak. The Chargers (5-8) dominated from the outset, never letting Steelers quarterback Ben Roethlisberger get comfortable in his first game in nearly a month.
Roethlisberger completed 22 of 42 passes for 285 yards and three second-half touchdowns. But he also threw an interception and had a botched screen pass turn into an easy Chargers touchdown as the Steelers (7-6) hardly played like a team readying for a postseason run.
