After three and a half years of struggle, sacrifice, and success, the U.S. Men’s National Team heads to the Maracanazinho in Rio de Janeiro, Brazil, for the AIBA Americas Continental Olympic Qualifier from May 4-13.  A high enough finish in the tournament will lead to ultimate entry into the London Games.

A total of 38 Olympic berths will be spread across ten weight classes.  Nations from North, Central, and South America will compete for them.  Out of the 10 members in Team USA, three have already qualified by reaching the quarterfinals of last year’s AIBA World Championships (flyweight Rau’shee Warren, bantamweight Joseph Diaz Jr., and welterweight Errol Spence Jr.).

“It's time to make America proud!” exclaimed light welterweight Jamel Herring via Twitter.  “Continue to keep us in your prayers back at home.”
