LONDON, ENGLAND (WHBL) - Thirteen Wisconsin athletes will march in with their respective teams today, as the Summer Olympics begin in earnest in London with the Opening Ceremony. Stevens Point native Lauren Sesselmann has already started her Olympic experience. She played 71 minutes for Canada on Wednesday, in a 2-1 loss to Japan. Sesselmann, a defenseman who went to Green Bay Notre Dame High School, did not figure in the scoring. She’ll be back in action tomorrow when the Canadians play South Africa. Ten Wisconsin athletes are part of the 529-member U-S delegation. Two-time fencing medalist Mariel Zagunis will carry the flag and lead the team into the Olympic Stadium during today’s Opening Ceremony. It’s in recognition of the 40th anniversary of Title-Nine, the program that requires equal opportunity for male and female athletes in school sports. London’s time is six hours ahead of Wisconsin’s. And that means most of us will be sleeping when three other Wisconsinites begin their Olympic journeys tomorrow, all in rowing. Saint Croix Falls native Megan Kalmoe will compete in the women’s quadruple scrulls preliminaries. And former Badgers Grant and Ross James will be in the preliminaries of the men’s-eight event
