Third place at the 2012 USA Junior Championships brought Baisden a place in the relay at the World Junior Championships. At the competition in Barcelona the American team were disqualified in the heats, but were given a second opportunity to qualify after a protest and ultimately a team of Baisden, Erika Rucker, Olivia Ekpone and Ashley Spencer went on to win the gold medals. In 2013, she improved her best to 52.03 seconds while placing second at the national junior championships and later won her first individual international medal at the 2013 Pan American Junior Athletics Championships, coming runner-up behind Courtney Okolo before taking the relay gold with her teammate.
