Terry Bradshaw, passing with precision on a frigid, snow-covered field, threw for three touchdowns to lead the Pittsburgh Steelers to a 35-13 victory over the Baltimore Colth today.

Amid temperatures in the mid-20s, both sides slipped and shivered as the Steelers raised their record to 13-2, assuring them of the home-field advantage if they make it to the American Congerence title game.

The Colts, whose white uniforms blended with the playing field's halfinch cover of snow, fell to 5-10.

Bradshaw hit 11 of 18 passes for 240 yards and touchdown passes of 31 yards to John Stallworth, 12 yards to Randy Grossman and 29 yards to Jim Smith.

Bradshaw said he enjoyed the weather conditions, despite the freezing temperature.

"We threw everything at them. I came out and decided to just keep throwing at them and see what happened," Bradshaw said. "I had a lot of time. The snow was a luxury, really. The footing was bad, and the Colts couldn't get in."

The Steelers, who clinched the AFC Central title last week in Houston, had a 21-7 halftime lead with the help of two short touchdown runs by Franco Harris.

Baltimore cut the nargin to 21-13 early in the third quarter when line-backer Derrel Luce returned a Brad-shaw fumble 44 yards for a touchdown. A 57-yard kickoff return by Larry Anderson set up the first of Bradshaw's two second-half touchdown passes.

In the first quarter, Pittsburgh drove 55 yards to score on Bradshaw's 31-yard pass to Stallworth, who was sidelined the second half by a stomach virus.

Late in the first quarter, Bradshaw hit Lynn Swann on a 62-yard pass play to set up a three-yard touchdown by Harris on the opening play of the second quarter.

Swann, who spun loose from a pack of defenders on the long pass, sat out the second half with a head injury.
