Evanston, Ill. - NCAA All-American Nick Simmons has been dominant on the college scene for two seasons. He is now beginning to dominate the freestyle scene as well.    On Saturday, Simmons pinned four of his five opponents, three of them in the first period, to win a gold medal at 55 kg/121 lbs. at the University Freestyle National Championships.    The title was the first for Simmons since 2003, when he also placed first at 55 kg.    Another 2003 champion that won a gold medal on Saturday was Jason Mester of Central Michigan at 66 kg/145.5 lbs. Mester defeated Cliff Moore of the Hawkeye WC in the finals, 2-0, 1-1, 1-0, with the final period point coming in the leg clinch.    Mester had to win seven matches to get to the gold medal, a feat only two wrestlers in the University freestyle division had to endure.    The other was Matt Pell of the Tiger WC at 74 kg/163 lbs.    Pell, who was an NCAA All-American at 184 lbs., dropped down in weight and overpowered 2004 NCAA champion Matt Gentry of Stanford in the finals, 8-2, 4-2. Pell won seven matches overall, two of them by fall.    Tyler Nixt of the Hawkeye WC also won a hard-fought gold medal at 84 kg/185 lbs. In the finals, Nixt defeated two-time NCAA finalist Ben Askren of the Tiger WC, 2-1, 1-1. All of the scoring in the match came off of takedowns, and in each period, Askren scored first.    However, the new rules give a 1-1 tie to the wrestler who scored the last takedown, giving the second period and the win to Nixt.    J.D. Bergman of the Ohio International WC was the only University double champion this year. Bergman won by an injury default over Tommy Rowlands of the Sunkist Kids at 96 kg/211.5 lbs. Rowlands, who coaches Bergman in college, chose not to compete against his pupil.    The biggest surprise winner of the tournament may have been at 120 kg/264.5 lbs., where Israel Silva of Chattanooga came away with the gold medal.    Silva was practically unheard of entering the tournament, but he downed some of the top young heavyweights in the country on his way to the title, including Jamie Rakevich of Orange Crush, 6-0, 3-0, in the quarterfinals, Kyle Massey of the Wisconsin WC, 3-1, 0-2, 1-0, in the semifinals and Ty Watterson of the Orange Crush, 1-0, 1-0, in the finals.    At 60 kg/132 lbs., Drew Headlee of the Pitt WC wasted no time in winning his gold medal, pinning Jeremy Mendoza of the Sunkist Kids midway through the first period of their finals bout. The only close match Headlee endured during the tournament was in the semifinals, when he downed Pat Castillo of Northern Illinois, 3-3, 6-3.    Daniel Jackson of Minnesota won a title at 50 kg/110 lbs. uncontested.    The University National Championships qualify wrestlers for the University World Team Trials to be held in Colorado Springs, Colo., May 22-29. Champions from this tournament will receive an automatic bid into a best-of-three championship series to determine this year's University World Team representative at the World University Games in Izmir, Turkey, August 1-7.
