Penn State grounded Iowa's best-in-the-Big Ten passing attack, Silas Redd ran for 142 yards and Matt McGloin capitalized on a fourth-quarter turnover with a touchdown pass in a 13-3 win Saturday.
Clinging to a 6-3 lead with 14:21 left, linebacker Gerald Hodges sacked quarterback James Vandenberg and forced a fumble recovered by Nate Stupar at the Iowa 49.
The Nittany Lions (5-1, 2-0) pounded away at the tired Hawkeyes with 10 straight runs to the 2 before McGloin rolled right to find wide-open tight end Kevin Haplea a 13-3 lead with 8:08 to go.
It was more than enough cushion for Linebacker U's tough defense. Vandenberg threw two interceptions over the last seven minutes and Iowa (3-2, 0-1) stumbled in its conference opener after a bye last week.
