It felt like a title fight -- even if it was just Team USA's opening punch. 

The only American boxer to enter the ring on Saturday, women's lightweight Jajaira Gonzalez was a flurry of hard-hitting fists against aggressive French opponent Estelle Mossely. The fight was close, but the victory a decisive 4-0. 

Gonzalez punched her ticket into the Round of 16 as her seven Team USA compatriots prepare for their first fights at the Paris 2024 Olympics later this week.
