IOWA CITY, Iowa - Iowa tossed Michigan State off the pile of unbeaten teams and turned the Big Ten race into a scramble for the Rose Bowl.

Ricky Stanzi threw three touchdown passes, and defensive backs Tyler Sash and Micah Hyde combined for a spectacular score on an interception return, as the Hawkeyes, ranked 18th in the BCS, stomped the No. 5 Spartans, 37-6, yesterday.

Adam Robinson scored a pair of touchdowns for charged-up Iowa, which rolled out to a 30-0 halftime lead and dealt a crushing blow to the Spartans' national title hopes.

"Did we come unprepared? I don't think so," Michigan State coach Mark Dantonio said. "Did things snowball on us? I guess they did."

Iowa (6-2, 3-1 Big Ten) needed just 15 minutes to jump ahead 17-0, as Hyde dashed 66 yards after taking a pitch from Sash, who had picked off a pass.

Stanzi then found Robinson for a 32-yard TD pass, and Robinson's 2-yard touchdown run put the Hawkeyes ahead by 30 with 1:01 left in the first half.

Kirk Cousins threw three interceptions for the Spartans (8-1, 4-1), who were trying to move to 9-0 for the first time since winning a share of the national title in 1966. Michigan State can likely forget about that this year. But the Big Ten title is still up for grabs and Iowa is in the middle of the race, too.

"I thought the guys came out ready at kickoff, certainly, and for the first time we really put it together in all three phases," coach Kirk Ferentz said.

It was the second time in three years the Hawkeyes ended a rival's unbeaten season at Kinnick Stadium. Iowa stunned then-No. 3 Penn State, 24-23, in 2008 to boot the Nittany Lions out of the national title picture.

This win was the biggest over a ranked team in Ferentz's 12 seasons at Iowa.

Iowa opened with an 80-yard drive capped by a 3-yard TD pass from Stanzi to Colin Sandeman. Mike Meyer added a 37-yard field goal that put the Hawkeyes ahead 10-0 before the Spartans had a first down.

Sash and Hyde then teamed for the play of the season for Iowa. Sash jumped a route and picked off Cousins' pass at the Iowa 28.

Sash immediately chucked the ball back to Hyde, who cut across the length of the field and stretched for the pylon at the end.

"I knew the route. I've seen it 100 times on film," Sash said. "I kind of just jumped up and tossed it to (Hyde) and he did the rest of the work."

That put Michigan State behind 17-0 for the second week in a row.

Stanzi's third TD pass of the day, a 22-yarder to Marvin McNutt midway through the third quarter, made it 37-0. Cousins finally got the Spartans on the board with a 6-yard touchdown pass to B.J. Cunningham to start the fourth quarter.
