IOWA CITY, IOWA (AP) -- Ricky Stanzi threw three touchdown passes and No. 18 Iowa knocked fifth-ranked Michigan State from the ranks of the unbeaten in decisive fashion, stomping the Spartans 37-6 on Saturday.

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

Iowa (6-2, 3-1 Big Ten) jumped ahead 17-0 when Micah Hyde went 66 yards after taking a pitch from safety Tyler Sash, who had
picked off a pass.

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.
