IOWA CITY, Iowa (AP) — Officials say that over 7,500 tickets have been sold for the April’s U.S. Olympic team wrestling trials in Iowa City.

USA Wrestling events director Pete Isais says ticket demand for the 2012 trials is the highest it’s ever been.

The trial will determine who’ll wrestle for the U.S. in the London Olympics in August. They’ll be held April 21 and 22 at Carver-Hawkeye Arena.

Six former University of Iowa wrestlers are among the 175 athletes who’ve already qualified for the event.
