COLUMBUS, Ohio (Ticker) -- Overtime again went Ohio State's way.
Mike Nugent kicked a 36-yard field goal to open the extra session and watched Ben Jones miss from 37 yards out as the fourth-ranked Buckeyes kept alive their national title hopes and escaped with a 16-13 victory over 10th-ranked Purdue.
Ohio State (10-1, 6-1 Big Ten), currently third in the Bowl Championship Series standings, improved to 4-0 all-time in overtime games and will visit archrival Michigan next week in a game that will decide the Big Ten Conference title.
The Buckeyes won their first national title since 1968 last season, capped by a triple-overtime win over Miami in the Fiesta Bowl. Eleven of Ohio State's victories over the last two seasons have been decided by seven points or less, including a 10-6 win over Purdue last season that was decided on a late touchdown pass by Craig Krenzel.
"Our guys just keep playing," Buckeyes coach Jim Tressel said. "I think when you stop and start thinking (about close games), things don't work out."
"We've been there before, so it's just kind of go out and get the job done," said Jenkins, caught six passes for 123 yards, including a 60-yarder that set up a field goal in the first half.
Ohio State had a chance to win on the final play of regulation following a fumble by Kyle Orton, but Nugent had a 41-yard field goal attempt blocked.
Ohio State had the ball first and went ahead on Nugent's field goal. The game nearly ended when Ohio State's Chris Gamble dropped a sure interception.
The Boilermakers (8-3, 5-2) settled for a field goal try and Jones' kick was wide left, extending Ohio State's home winning streak to 16 games and sending the Boilermakers to their sixth straight loss in Columbus.
"We had our chances," Purdue coach Joe Tiller said. "It was a game of field position and turnovers and we didn't win either one of them."
Jones kicked field goals of 45 and 47 yards in the second quarter, but missed on a 27-yard attempt in the third quarter.
"I just slipped a little, but both of the field goals were on me," Jones said. "On the last field goal the snap was good, the hold was good. I just pulled it to the left."
Saturday's game was a battle of field goals before Purdue committed a pivotal turnover early in the fourth quarter. With Purdue pinned deep in its own territory, Orton lost control of the ball after he was hit by defensive linemen Will Smith and Tim Anderson.
Defensive end Mike Kudla picked up the ball at the one yard line and easily went into the end zone, giving the Buckeyes a 13-6 lead.
Purdue tied the game with 4:36 left on an 11-yard run by Jerod Void on a Statue-of-Liberty play in which Void took the ball out of Orton's hand and raced into the end zone. Void had 22 carries for 60 yards.
Nugent kicked field goals of 26 and 52 yards in the first half. Krenzel completed just 15-of-29 passes for 226 yards.
