LAS VEGAS - Doug Schwab hasn't wrestled a lot of matches this season.

But the University of Iowa assistant wrestling coach still arrived in Las Vegas this weekend more than prepared to make his first U.S. World Team.

Just ask No. 3 seed Jared Lawrence, No. 2 seed Zack Esposito and No. 1 seed Jared Frayer.

The sixth-seeded Schwab knocked off all three in succession to win the Challenge Tournament at 66 kg/145.5 lbs. and advance to meet U.S. Nationals champion Chris Bono on Sunday night in the U.S. World Team Trials championship series.

The best-of-3 finals are set for 6:30 p.m. Sunday at the Las Vegas Convention Center.

Champions on Sunday qualify for September's World Championships in Baku, Azerbaijan. A combined 11 champions in freestyle, Greco-Roman and women's freestyle were crowned on Saturday when the two-day competition kicked off.

Frayer executed a sweet lateral drop to win the first period 7-2 before the scrappy Schwab came back to win the final two periods 3-0, 1-0. Schwab, who competes for the Gator Wrestling Club, fired in on a nifty leg attack to gain the winning takedown in the final two-minute period. Schwab is a past NCAA champion for Iowa.

Frayer had earlier beaten 2006 World champion and No. 4 seed Bill Zadick 1-0, 6-0 in the semifinals. Zadick has missed nearly the entire season because of injuries and illness.

One of the afternoon's biggest upsets came when fifth-seeded Pat Cummins of the New York AC knocked off No. 1 seed Cole Konrad 0-2, 1-1, 1-0. Cummins then fell to Steve Mocco of the New York AC in the Challenge Tournament finals.

Mocco advances to meet U.S. Nationals champion Tommy Rowlands of the Sunkist Kids in the best-of-3 finals on Sunday night.

The women's freestyle finals at 48 kg/105.5 lbs. will match past World medalist Stephanie Murata against 2006 World Team member Mary Kelly. Murata beat Kelly in the finals of April's U.S. Nationals.
