Ajavon graduated from Rutgers University in 2008, having majored in Africana Studies. She was a key member of the 2006–2007 Scarlet Knights women's basketball team that reached the NCAA Championship game.
Ajavon played primarily off the bench during her rookie WNBA season, but averaged 8.0 points per game. When the Houston Comets folded in 2008, Ajavon was selected second in the dispersal draft by the Washington Mystics.
In her first season with Washington, Ajavon put up remarkably similar numbers to her first WNBA campaign. Again mainly playing as a reserve, she scored 8.0 points per game. Ajavon helped the Mystics reach the playoffs, where she played well, scoring 19 points in just 34 total minutes, but Washington suffered a two-game sweep at the hands of the Indiana Fever.
