ANN ARBOR, Mich. (AP) -- Ohio State overcame a slew of mistakes just in time to clinch at least a share of the Big Ten title.
Antonio Pittman's 3-yard run with 24 seconds left capped an 88-yard drive and gave the ninth-ranked Buckeyes a 25-21 win over No. 17 Michigan on Saturday.
Ohio State (9-2, 7-1) closed the regular season with six straight wins and gave coach Jim Tressel his fourth win in five games against Michigan (7-4, 5-3).
The Buckeyes rallied for the victory despite two turnovers and a shanked punt that led to scores, a missed extra point and field goal, mishandled punt returns and two pass interference penalties in the end zone.
Michigan was essentially playing mistake-free football when it led 21-12 midway through the fourth quarter before Ohio State quarterback Troy Smith rallied his team to a victory.
Smith's 26-yard pass to Santonio Holmes made it 21-19 with 6:40 to go.
Michigan then drove to Ohio State's 34 and chose to have Garrett Rivas pooch punt, instead of kicking a long field goal into the wind.
Smith started the winning drive at the Buckeyes 12 with 4:18 left and made a series of clutch plays, including a 26-yard pass to Anthony Gonzalez to Michigan's 4, to set up Pittman's TD.
Michigan got to midfield, but its comeback hopes ended when receiver Tyler Ecker caught a short pass and tried to gain yards instead of running out of bounds.
As the final seconds ticked off the clock, the Buckeyes ran across the field and celebrated with their fans in the corner of Michigan Stadium.
While they travel home by bus, the Buckeyes will find out whether they have to share the Big Ten title with Penn State.
If the Nittany Lions win at Michigan State, they will have a piece of the conference championship with Ohio State and will earn the automatic Bowl Championship Series bid because of their win over the Buckeyes, who would still have a strong possibility at getting an at-large bid in the BCS. Ohio State will win the title outright if the Spartans beat Penn State.
Michigan's loss could end its nine-year streak of playing in January bowls.
Smith was 27-of-37 for 300 yards with a TD pass, and ran for 37 yards and a score, one year after his spectacular performance led Ohio State to a win over Michigan.
Pittman had 85 yards rushing and a TD. Ted Ginn Jr., who had trouble fielding punts, caught nine passes for 89 yards and Holmes had 72 yards receiving and a score.
Chad Henne, who had to throw because Michigan couldn't run, was 25-of-36 for 223 yards and a TD. Steve Breaston had seven receptions for 53 yards.
Mike Hart, who aggravated an ankle injury early in the second half, was held to 15 yards rushing on nine carries and his replacement, Kevin Grady, ran for just 11 yards.
Ohio State led 12-7 at halftime and probably would've held Michigan scoreless had Maurice Wells not fumbled -- on his only carry -- at the Buckeyes 36 early in the second quarter.
The Buckeyes outgained Michigan 200-103, but had to settle for two field goals in the first half.
Early in the third quarter, Michigan's LaMarr Woodley split two Buckeyes blockers and knocked the ball out of Smith's hands to set up Rivas' 27-yard field goal to make it 12-10.
Another Ohio State miscue, an 18-yard punt to its 37, helped Michigan take its first lead.
Grady's 2-yard run, a play after a pass interference penalty in the end zone, and Henne's 2-point conversion run gave the Wolverines an 18-12 lead late in the third quarter.
Ohio State then put together its first solid drive of the half, but Josh Huston missed a 46-yard field goal.
On the ensuing possession, Henne's sneak picked up a first down on a fourth-and-1 from Michigan's 38. That gutsy call kept alive a drive that ended with Rivas' 19-yard kick, giving the Wolverines a 21-12 lead with 7:49 left.
On a sunny, windy and crisp day, the Buckeyes were dominate early -- and late.
Ohio State opened the game with an 80-yard, 13-play drive capped by Smith's 4-yard run, then Huston missed his first extra point of the season.
Michigan drove to Ohio State's 28 on the ensuing possession, but instead of attempting a field goal with the wind, it chose to go for it on a fourth-and-1 and Henne threw an incomplete pass.
Huston kicked a 47-yard field goal to give the Buckeyes a 9-0 lead on their second drive.
Wells' fumble, caused by Pierre Woods and recovered by Gabe Watson, set up Michigan's only score in the first half. One play after a pass interference penalty was called on third down, Jason Avant caught a 2-yard TD pass in the corner of the end zone.
Huston's 25-yard kick with 23 seconds left in the half gave Ohio State a 12-7 lead, and its third score on four drives.
