López won the U.S. Olympic Trials but Carlos Balderas had already secured the United States' sole lightweight entry into the tournament as AIBA's World Series of Boxing champion, so López was aware entering the trials that at best he could only qualify as an alternate for Balderas (who lost in the Olympic quarterfinals). López was able to qualify for the Honduran team, where his parents are from, and reached the finals of the Olympic qualifying tournament for the Americas to earn his place in Rio. López also won the 2015 National Golden Gloves. López competed in the men's lightweight event at the 2016 Summer Olympics representing Honduras, where he was defeated in the tournament by eventual silver medalist Sofiane Oumiha.
