Four years after an embarrassing shutout, the U.S. will medal in the Olympic boxing tournament.

Kansas fighter Nico Hernandez is guaranteed to win at least a bronze and become the first American to medal in the tournament since 2008.

Hernandez moved to 3-0 with a tight unanimous decision victory over Ecuador’s Carlos Quipo.

Hernandez won 29-28 on all three cards and leaped in the air when the decision was read. Quipo dropped to his knees in stunned disbelief, losing the third round 10-9 after the judges scored it 19-19 through two.

Hernandez was coming off an upset win over the No. 2 seed in the light flyweight bracket, Vasilii Egorov of Russia.

The U.S. team is a surprising 5-1 at the Olympics with one more fight Wednesday night. The nine-man American team won only five fights in London and failed to bring home any medals for the first time ever.
