STATE COLLEGE — Spencer Petras smiled and admitted he’s not the strongest runner when he has the football in his hands.

But Iowa’s quarterback doesn’t have to be, especially when the 300-pounders in front of him do most of the hard work like they did on Saturday in Iowa’s 41-21 win over Penn State.

Petras completed 18 of 28 passes for 186 yards and ran for a late touchdown to lead Iowa to its third straight win and first at Beaver Stadium since 2009. The Hawkeyes (3-2, 3-2 Big Ten) got a combined 179 rushing yards and three touchdowns from Mekhi Sargent and Tyler Goodson, who ran through wide-open lanes and cut around missed tackles to snap Iowa’s six-game losing streak in the series.

Iowa led 31-7 midway through the third quarter before Sean Clifford replaced Will Levis at quarterback for Penn State. Clifford completed a pair of touchdown passes for 96 yards in a 3:54 span that cut Iowa’s lead to 10 with just over a quarter left.

Clifford was 13 of 22 with 174 yards and two interceptions for the Nittany Lions, who fell to 0-5 for the first time in their 134-year history. Penn State is now playing for pride.
