UNDATED (AP) -- The Pittsburgh Steelers made the defending AFC champions look rather average during their visit to Foxborough.

Ben Roethlisberger threw two touchdown passes during a string of 30 unanswered points as the Steelers humbled the New England Patriots 33-10.

Jeff Reed added four field goals for Pittsburgh, which at 9-and-3, maintains a one-game lead over Baltimore atop the AFC North. The Patriots fall to 7-and-5 and into a second-place tie with Miami in the AFC East.

The Patriots could manage only 267 yards against the NFL's top defense. Matt Cassel (KA'-sihl) lost two fumbles and was picked off twice in the second half.

The Steelers have held all 12 opponents to under 300 yards.
