No. 10 Iowa forced four turnovers and downed No. 9 Iowa State 27-17 Saturday in Ames, Iowa, to retain the Cy-Hawk Trophy.

Despite gaining only 173 yards of total offense, Iowa (2-0, 1-0 Big Ten) defeated a ranked opponent for the second straight week to open its season. Spencer Petras completed 11 of 21 passes for 106 yards and a touchdown, and Tyler Goodson rushed for 55 yards and a touchdown.

Breece Hall finished with 69 rushing yards and one touchdown for Iowa State (1-1). Senior quarterback Brock Purdy was benched after going 13-for-27 for 138 yards and three interceptions, two of them to Hawkeyes defensive back Matt Hankins.

It was the first time in the Cy-Hawk rivalry that both teams were nationally ranked for the game. Iowa extended its series winning streak to six.

The Cyclones struck first with a 23-yard Connor Assalley field goal in the final minute of the first quarter. But their next possession ended in Purdy's first pick of the day, snagged by Hankins on a leaping play at midfield.

That set up a short scoring drive for Iowa, capped off by Goodson's 4-yard touchdown run.

The Hawkeyes went 71 yards on their next offensive drive, and Petras found receiver Charlie Jones over the top for a 26-yard score to make it 14-3 with 1:01 left in the half.

Iowa State didn't lie down before halftime. Purdy strung together several quick completions and hit Darren Wilson Jr., who sprinted right for a 49-yard gain and a near-touchdown. Hall punched it in from four yards out on the next play for a 14-10 halftime deficit.

At the start of a Cyclones drive late in the third, Iowa linebacker Jestin Jacobs stripped the ball out of Hall's grasp and Jack Campbell picked it up for a 6-yard return touchdown.

The scoop and score broke the game open. Purdy threw picks on his next two drives and was replaced in the fourth quarter by Hunter Dekkers. The redshirt freshman completed a 13-yard touchdown pass to Tarique Milton with 3:27 left the game, but the Cyclones couldn't recover an onside kick to sustain their chances of a comeback.

Iowa kicker Caleb Shudak converted two field goals in the second half, one from 51 yards.
