SOUTH BEND, Ind. (AP) — Kyren Williams ran for 112 yards and two touchdowns in his first start, grad quarterback Ian Book threw for 263 yards and No. 10 Notre Dame beat Duke 27-13 on Saturday at rainy Notre Dame Stadium in the season and Atlantic Coast Conference opener for both teams. The speedy Williams, who saw limited action last season as a freshman, had 19 carries and also was Notre Dame's leading receiver with two receptions for 93 yards, one a 75-yarder in the first half. The victory was Notre Dame's 19th straight at home and the first for the Fighting Irish in a conference after 132 years as an independent. Because of COVID-19, the Irish are playing this season as a member of the ACC.
