Alston was drafted in 2009 out of Indiana by the New England Revolution and took the league by storm. In his second season, he was a starter for the MLS All-Star team that took on Manchester United in Houston, and he continued to start almost every game for the Revs for the next two years until the beginning of the 2013 season, when he was diagnosed with a rare but treatable form of Leukemia.
After going through treatment and getting cleared medically, he came back to soccer and continues his career as a player, as well as dabbling in a few other ventures.
