BCSNN — After two difficult road losses and weeks of offensive frustration, Iowa State returned home and delivered its biggest win of the season in unforgettable fashion.

Kyle Konrardy drilled a 34-yard field goal as time expired Saturday night, capping a frantic final drive and lifting the Cyclones to a 51-49 upset victory over No. 24 Oklahoma State in a Halloween-weekend shootout at MidAmerican Energy Field at Jack Trice Stadium.

The win snapped Iowa State's two-game losing streak and gave first-year coach Jimmy Rogers one of the signature victories of his young tenure. It also produced the highest-scoring game in the 60-year history of the rivalry, as the teams combined for 100 points and 1,114 yards in front of a festive crowd dressed to match the occasion. Iowa State wore all black, Oklahoma State all orange, and the game quickly turned into a thriller worthy of the setting.

The Cyclones (4-4, 2-3 Big 12) appeared in control entering the fourth quarter with a 38-28 lead, but the final 15 minutes featured six touchdowns, three lead changes and constant momentum swings.

No swing was bigger than Oklahoma State's final go-ahead drive.

After Iowa State had taken a 48-42 lead on Konrardy's 29-yard field goal with 2:56 remaining, the Cowboys answered immediately. Quarterback Drew Mestemaker directed a 75-yard march in just over two minutes, ending it with an underhand shovel pass to Wyatt Young for a 7-yard touchdown that put Oklahoma State ahead 49-48 with only 53 seconds left.

That proved to be too much time for the Cyclones.

Starting at their own 37-yard line, quarterback Jaylen Raynor found freshman receiver Jamal Polite Jr. for a spectacular 33-yard gain as Polite adjusted to a pass thrown behind him. Running back Aiden Flora then ripped off runs of three and 11 yards to move the ball into range before Rogers called on Konrady, who had already connected from 39 and 29 yards earlier in the game.

The junior kicker delivered again, splitting the uprights from 34 yards away as time expired for his third career game-winning field goal.

Konrardy's heroics capped a night in which Iowa State's offense finally rediscovered its explosiveness after scoring just 13 points combined in consecutive losses to BYU and Arizona.

Raynor turned in his best passing performance of the season, completing 18 of 28 passes for 309 yards and three touchdowns. He added 48 rushing yards and another score on the ground. His touchdowns went to Easton Miller, Polite, and Cameron Pettaway, while consistently answering Oklahoma State every time the Cowboys threatened to seize control.

Flora was equally dominant. The running back rushed for a career-high 221 yards on 29 carries, scoring on runs of 29 and 75 yards. His 75-yard sprint came immediately after Oklahoma State had cut Iowa State's lead to 38-35 early in the fourth quarter, restoring momentum to the home sideline. Flora now has 937 rushing yards on the season and continues to lead the Big 12 in yards per carry.

Polite delivered a breakout performance of his own. After entering the night with only eight catches all season, the freshman finished with career highs of six receptions for 171 yards and a touchdown, repeatedly stretching the Cowboys' defense and providing Raynor with a game-changing deep threat.

Iowa State's special teams created momentum early as well. After tying the game at 14 in the second quarter, Konrardy executed a surprise onside kick and recovered it himself near midfield. Three plays later, Raynor connected with Polite on a 43-yard touchdown pass that gave the Cyclones their second-quarter lead. Iowa State also capitalized on a muffed Oklahoma State punt recovered by Caleb Schmidt, turning the turnover into a field goal before halftime.

The Cowboys (5-3, 3-2 Big 12) matched Iowa State blow for blow throughout the night. Mestemaker completed 27 of 42 passes for 323 yards and five touchdowns, while Caleb Hawkins totaled 194 rushing yards, two rushing scores and a 59-yard touchdown reception. Oklahoma State finished with 533 yards and produced five separate 75-yard scoring drives.

But one turnover proved costly. Beau Goodwin's fourth-quarter interception of Mestemaker set up Iowa State's late field goal drive and helped swing momentum back toward the Cyclones.

When the final kick sailed through the uprights, Iowa State had secured its first win over a ranked opponent since defeating Kansas State in last season's opener in Ireland and posted its highest point total in a Big 12 game since scoring 59 against Kansas in 2021.

The Cyclones head back on the road next week to face Baylor before returning home Nov. 14 to host Cincinnati. For one night, though, Iowa State's rebuilt roster and first-year coaching staff delivered exactly what the home crowd wanted: a memorable upset in one of the wildest games of the college football season.
