The United States Olympic Education Center (USOEC) in Marquette, Mich. sent a team of Greco-Roman wrestlers overseas for a winter tour. In the first two days of competition, the team went 1-1-1 against a Bulgarian Junior national team in Sofia, Bulgaria.    The squad defeated Bulgaria 7-5 in the first dual on March 3. On March 4, the squad then lost to a different Bulgarian team 7-4 and tied a third squad 4-4 later that day. Points were accumulated based on the number of wins in the duals, not classification points.    Joe Espinoza (Marquette, Mich./USOEC) was the only American wrestler to win all three of his matches. Espinoza defeated Georgi Andreev by a 10-0 technical fall in his first match while pinning his next two opponents.    Recording two wins for the USOEC were Joe Betterman (Marquette, Mich./USOEC) and Harry Lester (Marquette, Mich./USOEC).    The team is coached by Ivan Ivanov of Marquette, Mich.    The USOEC will continue its travels through Europe this week. Results will be provided by TheMat.com when they become available.
