ST. LOUIS — Tony Nelson made a promise to himself on the night of Dec. 4, 2011.
The Gophers sophomore heavyweight had just dropped his second successive match after winning the first seven of the season.
"I just kind of had a mental lapse that weekend," Nelson recalled. "I told myself that was never going to happen again."
It didn't.
Nelson capped a perfect second-half run with a dramatic 4-1 victory over defending champion Zachery Rey of Lehigh on Saturday in the heavyweight championship match of the NCAA Wrestling Championships before a sellout crowd of 18,919 at the Scottrade Center.
The Cambridge native ended the season 32-2 and became the first sophomore heavyweight champion in school history.
Nelson's title helped the Gophers to a strong second-place showing in the team standings with 117.5 points. Defending champion Penn State amassed 143 points by winning three individual championships.
The second-seeded Nelson won his final 25 matches this season and saved his best for last. He recorded a two-point takedown with seven seconds left in the third period to break a 1-1 tie. The slick move brought a roar from the large Minnesota contingent in attendance. Nelson looked at his supporters and flexed his muscles seconds after the final horn sounded.
