ANN ARBOR, Mich. -- Ohio State followed up its worst with its best.
One week after struggling against Michigan State, the Buckeyes dominated archrival Michigan 42-13 on Saturday to spoil Jim Harbaugh's coaching debut in one of college football's most storied rivalries.
Running back Ezekiel Elliott rushed for 214 yards and two touchdowns, and quarterback J.T. Barrett added 139 yards on the ground, 113 yards passing and four total touchdowns.
The eighth-ranked Buckeyes (11-1, 7-1 in the Big Ten) clinched at least a share of the Big Ten East division championship for a fourth consecutive season.
Ohio State still has a path to the Big Ten championship if Michigan State loses to Penn State later today.
Harbaugh, a former Michigan quarterback who tormented Ohio State in the 1980s, was attempting to continue an odd trend. Seven of the previous eight Wolverines coaches won their first meeting against the Buckeyes.
Instead, No. 10 Michigan (9-3, 6-2) had no answer for Ohio State's rushing attack.
The Buckeyes piled up 371 yards rushing and five touchdowns on the ground.
Elliott, one week after a 12-carry, 33-yard performance against the Spartans, nearly approached the school record for rushing yards against Michigan, set by Carlos Hyde (226 yards) in 2013.
Michigan entered the game with the Big Ten's top rushing defense at 79.5 yards per game and was ranked fourth nationally.
However, the tone was set late in the first quarter when Elliott scampered for a 66-yard gain two plays after Michigan roughed Ohio State punter Cameron Johnston.
Barrett capped the drive with a seven-yard touchdown run, his first of a career-high three for the day.
The teams traded scores in the second quarter, with Ohio State leading at halftime 14-10, as the Wolverines took momentum into the locker room after a late touchdown.
But the Buckeyes quickly dimmed the positive outlook for many of the 111,829 in attendance at Michigan Stadium.
Ohio State scored on its first four possessions of the second half on a 25-yard pass from Barrett to Jalin Marshall, a 13-yard run by Barrett, a 10-yard run by Elliott and a 17-yard run by Barrett.
Michigan quarterback Jake Rudock, who was injured in the third quarter, completed 19-of-32 passes for 263 yards and a touchdown.
The Wolverines could muster only 57 yards rushing on 25 carries. They were limited to 138 yards of offense in the second half after piling up 226 yards in the first half.
