Horton played club soccer for Ohio FC Mutiny for the first 10 years of his career and in that span won the state championship 8 times in a row.
Upon his return from Bradenton, Horton then made a crucial move to play with longtime rival Chicago Magic in the new academy system.
The following year Horton returned to Ohio and was part of the Columbus Crew Soccer Academy after committing to play at the University of Louisville in 2010.
Horton then played a major role with the Cardinals and helped them reach the NCAA Men's College Cup for the first time in school history.
He played in 23 games for Louisville, and scored three goals, two of which were last-minute winners in the NCAA tournament - one in a 5-4 quarter final victory over UCLA, and one in a 2-1 semifinal win over University of North Carolina.
