COLUMBUS, Ohio (WCMH) -- Ohio State turned a 7-0 halftime lead into a dominant 35-7 win over Iowa as the third-ranked Buckeyes improved to 5-0 heading into a highly anticipated top ten showdown at Oregon next week.  Emeka Egbuka led the way with three touchdowns, including the first score of the day after catching a 14-yard throw on the opening drive to give OSU an early 7-0 lead.  The game became a defensive battle for both sides until the third quarter when Jeremiah Smith made two highlight worthy catches to double the Buckeyes lead. The freshman wideout hauled in a 53-yard pass from Will Howard to get inside the redzone before making a one-handed grab in the endzone for his sixth touchdown of the season.
