Yianni Diakomihalis made history on Saturday, becoming the fifth Division I wrestler to win four national titles. The Cornell wrestler won his fourth NCAA Division I Wrestling Championship in Tulsa, Oklahoma in front of a crowd that included former President Donald Trump. Penn State also continued its dominance, winning its 10th team title in 12 years. Trump shook hands and took selfies with fans and greeted several of the national champions. He sat with staff members and U.S. Senator Markwayne Mullin, and the crowd stood when he went to the arena floor. Diakomihalis, a senior from Lansing, New York, won the 149-pound title with a 7-2 win over Princeton’s Matthew Kolodzik. He joined Cael Sanderson of Iowa State (1999-2002), Pat Smith of Oklahoma State (1990-92, 1994), Kyle Dake of Cornell (2010-13) and Logan Stieber of Ohio State (2011-14) as four-time champions. Penn State finished with 125 points, far ahead of runner-up Iowa with 95.5. The Nittany Lions have now won 10 of the past 12 team titles and 13 of the past 17. "It's a special feeling," Diakomihalis said. "It's something that I've worked for my whole life. I'm just so thankful to have been able to accomplish it."
