The stars (and stripes) aligned for 29-year-old American flyweight (51 kg/112 lbs) boxer Roscoe Hill, who kicked off his 2024 Paris Olympics medal campaign with a 5-0 victory over Omad Ahmadisafa in the North Paris Arena.  

It was the second victory in as many days for American boxers, following lightweight (60kg/132lbs) Jajaira Gonzalez's fiery 4-0 victory over France's Estelle Mossely on Saturday. 

With eight boxers across 13 events, Team USA has plenty of talent in the tank: Jennifer Lozano (flyweight, 50kg/110lbs), Alyssa Mendoza (featherweight, 57kg/125lbs), and Morelle McCane (welterweight, 66kg/145lbs) all have yet to enter the ring. 

On the men's side, featherweight Jahmal Harvey and welterweight (71kg/146lbs) Omari Jones wait to hit the mat in Paris later this week. Super heavyweight (92+kg/202+lbs) Joshua Edwards clashes with Italy's Diego Lenzi on Monday. 

The 2024 Paris Olympics mark the first time any of these American boxers have competed at the Olympic level. 

Cuba's two-time Olympic gold medalist Julio Cesar La Cruz fell short in his bid for an historic trifecta. 

In a stunning upset, the heavyweight fell to Loren Alfonso -- a fighter from Azerbaijan who was born in Cuba -- in a split 3-2 decision. 

The light heavyweight champion at the 2016 Rio Games and heavyweight champion five years later in Tokyo, La Cruz had hoped to become only the fourth boxer to win three Olympic gold medals alongside Teofilo Stevenson, Felix Savon and Lazlo Papp.

However, La Cruz's light heavyweight compatriot Arlen Lopez Cardona can still achieve the feat, having also won gold in Rio and Tokyo. Cardona enters the squared circle on Tuesday. 

Monday will see Round of 16 matches for the men's lightweight (63.5kg/139lbs) and super heavyweight (92+kg/202+lbs) boxers, as well as women's lightweight (60kg/132 lbs) fighters.
