Over 20 upsets went down in week 15 including fove top-10 upsets. Here are the five biggest upsets of the weekend followed by all the upsets we could find. As always, if you saw an upset we missed, please email david.bray@flosports.tv so we can include it.

Darmstadt Downs #3 Brucki

Cornell's #10 Ben Darmstadt took out #3 Pat Brucki in a dual that decided the Ivy League title between Cornell and Princeton. Darmstadt's win moves him to 2-0 in college against Brucki. Their last meeting came during the Cornell vs Princeton dual in 2018.

While Darmstadt's win wasn't enough to give Cornell the dual meet victory, it does demonstrate that Darmstadt, who was previously ranked #10, remains an All-American contender after missing last season.

#19 Pagano Over #7 Laird in New Jersey Showdown

Rutgers and Rider met in an all-New Jersey battle on Sunday night. Rutgers won a number of tight bouts including #19 Jordan Pagano over #7 Ethan Laird at 197.

Pagano and Laird were tied at the end of regulation. Pagano converted a single-leg as time expired in sudden victory to complete the upset and fire up the Rutgers bench.

True Freshman Buchanan Takes Out #8 Geer

Wyoming true freshman Stephen Buchanan has been in a number of close matches with highly-ranked opponents this season, but he had yet to notch a top-10 win until this weekend.

Oklahoma State took the first eight matches in their dual with Wyoming, but Buchanan came out firing against #8 Dakota Geer at 197. The match was a back-and-forth affair. Trailing 6-5 in the third, Buchanan hit a duck-under off a Geer snapdown and rode Geer for the remainder of the match.

This was the biggest win of Buchanan's career and is a good sign for the true freshman as he moves toward the postseason.

Witcraft Knocks off #8 Bridges

Wyoming wasn't the only team with a top-10 upset in the dual with Oklahoma State. Freshman 133-pounder Reece Witcraft made his mark on the dual by beating #8 Montorie Bridges.

Witcraft and Bridges spent much the match in the handfight with Witcraft often pulling Bridges into a front-headlock position.

In overtime, Witcraft used a low-level attack to earn a takedown for the win. This sets up a potential rematch at the Big 12 Championships in early March.

Colbray Edges #10 Mantanona

Iowa State's Sammy Colbray started the season ranked in the top five at 184 but has been trying to find consistency since then. He dropped to 174 after the New Year and has had mixed results.

On Sunday, Colbray wrestled #10 Anthony Mantanona in Norman, Oklahoma, in a dual with the Sooners. An overtime takedown gave Colbray the win. 

Colbray had lost three out of his last four matches, so this upset win came at the right time. With results like this, the 174 bracket at the Big 12 Championships is shaping up to be unpredictable and exciting.
