ANN ARBOR, Mich. (AP) -- Michael Hart ran for 151 yards and a season-high three touchdowns and No. 9 Michigan scored TDs the first five times it touched the ball in the second half to beat Northwestern 42-20 on Saturday.<br>
<br>
The Wolverines (9-1, 7-0 Big Ten) led the Wildcats by only one point at halftime before turning the game into a rout with scores on the ground, through the air and on a punt return. They have won 15 straight games at home and 13 conference games in a row.<br>
<br>
If Michigan wins next week at Ohio State, the defending Big Ten champions will earn at least a share of the conference championship.<br>
<br>
Northwestern (5-5, 4-3) has to beat Illinois and win at Hawaii for a second straight bowl bid and fifth in 10 years. <br>
<br>
Michigan's Chad Henne was 19-of-26 for 187 yards with two TDs. Hart has run for 975 yards in his last five games and 1,311 this season.<br>
<br>
Steve Breaston scored twice in 35 seconds, catching a 10-yard TD pass and returning a punt 67 yards for another TD, to give Michigan a 42-13 lead early in the fourth quarter.<br>
<br>
Hart's second TD came on a 4-yard run to put Michigan ahead 14-6 on the first drive of the second half. Hart surpassed the 100-yard mark during the possession and moved past Ohio State's Maurice Clarett (1,237 yards) into third place on the Big Ten list for single-season rushing by a freshman.<br>
<br>
With 1,311 yards rushing, only Wisconsin's Ron Dayne (2,109) and Minnesota's Darrell Thompson (1,376) ran for more yards than Hart as freshmen in the conference. <br>
<br>
Northwestern's Noah Herron ran for 156 yards and a TD on 23 carries. Brett Basanez was 23-of-43 for 211 yards and a score. Brandon Horn caught a 9-yard pass late in the game to make it 42-20.<br>
<br>
Mark Philmore, Northwestern's leading receiver and punt returner, missed his second straight game with a sprained right knee.<br>
<br>
The Wildcats drove deep into Michigan territory three times in the first half, but had just two field goals and a blocked field goal attempt to show for it. Joel Howells kicked for the first time this season in place of Brian Huffman, who has missed 10 of 17 field goals.<br>
<br>
The Wildcats trailed just 14-13 early in the third quarter after Herron ran through a hole in the middle of the line and scored on a 68-yard run. But Michigan then broke the game open.<br>
<br>
The Wolverines set an NCAA record this season by averaging 111,025 fans per game at Michigan Stadium.
