Carlos Hyde ran for 149 yards, including 106 yards and two touchdowns in the second half, to lead No. 4 Ohio State to a 34-24 victory over Iowa on Saturday.
It was the Buckeyes' 19th consecutive victory, the most in the nation and tying the second-best streak in school history.
But it didn't come easy. The Hawkeyes (4-3, 1-2 Big Ten) dominated offensively in the first half and led 21-14 at the break behind the passing of Jake Rudock and running of Mark Weisman and Damon Bullock.
Hyde tied it with the first rushing TD against Iowa this season on Ohio State's first drive of the third quarter, and the Buckeyes took over.
