IOWA CITY, Iowa — Fourth down, 10 yards and most likely the season was on the line for Ohio State.
The Buckeyes put the ball in Terrelle Pryor's hands, and he used his legs to help them escape Iowa with their Rose Bowl hopes intact.
Dan Herron rushed for a 1-yard touchdown with 1:47 left and No. 8 Ohio State rallied to beat Iowa 20-17 Saturday.
Pryor threw for 195 yards and a score for the Buckeyes including a 14-yard run on fourth down to keep the winning drive alive.
Ohio State is tied with Wisconsin and Michigan State atop the league heading into next week's showdown with rival Michigan in the Horseshoe. It also preserved the Buckeyes' shot for at least a share of the Big Ten title for a record-tying sixth year in a row.
"I was going to run the whole time," Pryor said. "I found running room, had some good blocking. I just cut it up and went and got the first."
No. 21 Iowa led 17-10 early in the fourth quarter on freshman Marcus Coker's 1-yard TD run. But Devin Barclay's 48-yard field goal brought the Buckeyes within 17-13, and Pryor engineered a 76-yard drive despite DeVier Posey's drop of a sure TD pass.
The Hawkeyes have allowed a go-ahead touchdown in the fourth quarter of each of their four defeats. Ricky Stanzi's fourth-down pass to Marvin McNutt was stopped 2 yards shy of a first down on Iowa's final drive.
"Losing games is frustrating, and losing close games is frustrating," Hawkeyes coach Kirk Ferentz said. "We didn't make enough plays to get it done in the fourth quarter."
Pryor's errant throw early in the fourth was tipped, picked off by Shaun Prater and returned to the Ohio State 27-yard line. Coker, in for a struggling Adam Robinson, followed with his 1-yard plunge. Coker had 70 yards on nine carries as Robinson didn't play until the second quarter because of what Ferentz called "academic indigestion."
