PITTSBURGH (AP) — Chris Boswell tied a franchise record with six field goals and the Pittsburgh Steelers limited Lamar Jackson and the NFL's top-ranked offense in an 18-16 victory over the Baltimore Ravens on Sunday. The Steelers (8-2) won their fifth straight behind Boswell and a defense that never let Jackson, Derrick Henry or the rest of the offense get into a rhythm, opening up a little breathing room atop the AFC North. Baltimore (7-4) was held to season lows in points and yards (329) while committing 12 penalties and turning the ball over three times — each miscue leading to a Boswell field goal — as Pittsburgh won for the seventh time in its last eight meetings in a rivalry that remains as chippy as ever.
