Braelon Allen rushed for 173 yards and three touchdowns to help No. 20 Wisconsin beat Northwestern 35-7 for its sixth consecutive victory on Saturday.
Graham Mertz threw two touchdown passes, and Wisconsin’s defense recorded four interceptions. Northwestern’s Andrew Marty was picked off three times for a second straight week.
Wisconsin (7-3, 5-2 Big Ten, No. 18 College Football Playoff) entered the day in a four-way tie for the Big Ten West lead with Minnesota, No. 19 Iowa (No. 20 CFP) and Purdue (No. 19 CFP). The Badgers already have beaten Iowa and Purdue. They visit Minnesota on Nov. 27 to close the regular season.
Northwestern (3-7, 1-6) lost its fourth straight.

The Badgers were playing their first game since losing running back Chez Mellusi to a season-ending knee injury. Mellusi, who got hurt during a 52-3 victory at Rutgers last week, entered Saturday’s action ranked fifth in the Big Ten in rushing (815) and second in carries (173).
Allen picked up the slack.
The 17-year-old freshman had the most productive performance of his young career while rushing for more than 100 yards for a sixth straight game. Allen totaled just 12 carries in Wisconsin’s first four games while the Badgers staggered to a 1-3 start.
“He knows how important he is to this group,” Wisconsin coach Paul Chryst said. “He’s got a great mix of he’s humble, he’s confident and I think today showed he’s got a chance to be special.”
Allen had seven carries for 86 yards during a 95-yard drive that put Wisconsin ahead for good. He started that series with a 37-yard scamper and ended it with a 2-yard touchdown.
The most spectacular of his 25 carries came late in the third quarter when he bounced off three defenders in the first 10 yards of a 33-yard touchdown that extended Wisconsin’s lead to 35-0.
Mertz completed his first nine pass attempts and went 18 of 23 for 216 yards, including touchdown passes of 13 yards to Danny Davis and 11 yards to Jake Ferguson. He completed passes to nine different teammates and was intercepted once.
Northwestern’s lone score came when A.J. Hampton returned a Julius Davis fumble 49 yards with 11:38 remaining. The fumble was forced by Xander Mueller.
After Northwestern wasted an opportunity to take an early lead, Wisconsin scored touchdowns on three straight possessions.
“We did not play complementary football today,” Northwestern coach Pat Fitzgerald said. “When we moved it, we turned it over. We had opportunities to get off the field and we lost some one-on-one battles and missed tackles. It’s disappointing.”
Northwestern marched 82 yards on 19 plays in its first series, but the drive ended when Caesar Williams picked off a Marty pass in the end zone. Marty was trying to throw to Stephon Robinson Jr. on second-and-goal from the 10.
