IOWA CITY, Iowa (AP) — Nate Stanley threw for 226 yards and five touchdowns, and Iowa throttled third-ranked Ohio State 55-24 on Saturday, dealing what’s likely to be a fatal blow to the Buckeyes’ playoff hopes. Josh Jackson added three interceptions for the Hawkeyes (6-3, 3-3), who beat their fourth top-5 opponent in their last five tries at home.

Iowa raced out to a 31-17 halftime lead on a pair of Stanley TD passes to Noah Fant. Stanley, following a successful and highly unusual fake field goal, later fired a 2-yard TD pass with a defender hanging onto his foot that put the Hawkeyes ahead 38-17 late in the third quarter.

J.T. Barrett threw a career-high four interceptions for Ohio State (7-2, 5-1, No. 6 CFP), which allowed its most points in a game under coach Urban Meyer. The Buckeyes committed nine penalties and gained just 371 yards in their most lopsided defeat since last year’s 31-0 loss to eventual national champion Clemson in the playoff.

Ohio State is sure to plummet in the polls because of the loss, although with so many Top 25 teams facing each other that fall might not be as drastic this week. Iowa got 1 point last week. The Hawkeyes will get a lot more of those on Sunday.

Up next: Iowa travels to face Wisconsin next week. The Badgers are now the Big Ten’s best hope — by far — for the playoff.
