New York - The U.S. men's and women's freestyle wrestling team started off red-hot Friday morning in the first session of the World Championships of Freestyle Wrestling at Madison Square Garden.    Of the 14 wrestlers entered (seven men, seven women) all 12 wrestlers that had first round matches won, putting the U.S. in great shape for the remainder of the pool competition.    Leading the way for the U.S. contingent were Eric Guerrero and Sara McMann. The two knocked off returning world medallists in their first pool matches of the tournament.  Guerrero's match with 1997 World Champion Mohammad Talaeli of Iran got the ball rolling.    Talaeli took the lead with an early takedown, but Guerrero responded, tying the match with two minutes remaining in the match.    "I thought I exposed him, but I looked up and didn't get the point," Guerrero said.  As time waned, each wrestler fought off each other's attempts and regulation ended with the score knotted at 1-1.    Talaeli didn't apply the clinch correctly at the start of overtime and was cautioned. As Guerrero and Talaeli tried to lock again, the referee again cautioned Talaeli, giving Guerrero two points and the match.    "You've got two chances to lock (your hands) and he didn't take either and was penalized for it," Guerrero said.    McMann's match with world Silver Medallist Sara Erikkson of Sweden ended the session on a supreme high-note for Lock Haven University graduate.    McMann scored points in a hurry, jumping up 3-0 in the first 30 seconds of the match. She continued, cradling up Erikkson with 21 seconds to go and securing the fall.     "It's unbelievable, she's tough. I thought I was going to go out there and have a six minute match," McMann said.    As far as preparation for Erikkson, an opponent she's lost to on more than one occasion, she said: "Terry (Steiner) and I were working on this months ago - GO WATCH CHINA!" yelling in the direction of Mat 1 where another wrestler in her pool was to wrestle.    Stephen Abas shook off a bad match, nearly blowing a two-point lead to top Russia's Mavlet Batirov in overtime. Tied at two going into the clinch, Batirov tried to throw Abas, but Abas countered, landing on top of Batirov for the two points and the victory.    Joe Williams and Cael Sanderson won their first pool matches, each shutting out their opponents.     Williams isn't overlooking anyone this year. "I'm my toughest opponent," he said when asked about looming competitors.     Daniel Cormier also registered a solid performance, knocking off Hakan Toc of Turkey 9-3. Cormier built a 9-0 lead on a series of explosive takedowns and cruised.  On the women's side, Patricia Miranda staved off a much-improved Lyndsay Beile of Canada 3-1.    "If I tech someone or win by one, it's not the outcome, but how I wrestle," she said.    Sally Roberts, taking part in her first world championships, was trailing 2-0 before she scored a fall over Aikaterina Tsimpanakou of Greece.    "You know, this is the greatest feeling of my life… but what's that going to say about my wedding day?" Roberts said.    Kristie Marano was the only other U.S. competitor with a pin in the first session.  Jenny Wong and Toccara Montgomery each won with shutout victories, while Tina George topped Julieta Okot 9-3.    Notes….Ali Reza Dabir of Iran, one the world's most dominant wrestlers, fell in overtime in his first match of the tournament to Bulgaria's Serafim Barzakov. … Bousavia Saitiev of Russia gave up a double-leg takedown early against Senegal's Jean Diatta, but then proceeded to score 29 unanswered points en route to a 34-2 tech fall. Saitiev elected to continue the match after taking an 11-1 lead.
