No. 8 Ohio St. 31, No. 21 Iowa 6

A.J. Hawk and the Ohio State defense stuffed Iowa's running game and kept Hawkeyes quarterback Drew Tate on the run all day.

Troy Smith threw two touchdown passes to Anthony Gonzalez and ran for two scores to support a dominant defensive performance by the eighth-ranked Buckeyes in a 31-6 victory over No. 21 Iowa on Saturday.

"The key was when they started out trying to run the ball and we were able to stop them," Ohio State defensive coordinator Jim Heacock said. "Once that happened, that gave us some flexibility to turn those guys loose.

Iowa (2-2, 0-1 Big Ten) finished with 18 rushes for minus-nine yards. Led by Hawk and Mike Kudla, the Buckeyes (3-1, 1-0) sacked Tate five times for minus-43 yards.

The Hawkeyes, averaging 428 yards per game, mustered just 70 through the first three quarters and 137 for the game. They were forced to punt on their first seven possessions, running one play in Ohio State territory -- and by that time the Buckeyes were in control 24-0.

"It was pretty much a one-sided football game both ways," Iowa Coach Kirk Ferentz said.
