D.C. United has signed 16-year-old academy forward Michael Seaton to a homegrown contract, multiple sources told the Insider.

Seaton played for the Freestate Soccer Alliance — a Bowie-based youth program that last month forged a partnership with United — and D.C.’s under-16 academy squad. In 2011-12, he was the team’s leading scorer in the U.S. Soccer Federation’s Development Academy regular season.

Seaton also appeared in United reserve league matches last season, featuring first-team players.

[UPDATE: Reached by the Insider, Seaton said he couldn’t comment. Some added details: He was born in Jamaica, moved to the United States at age 7 and is a U.S. citizen. He has played for Jamaica’s under-17 national team twice. He lives in Capitol Heights, Md., in Prince George’s County and attends Central High School.]

United officials did not want to comment. An official announcement is likely this coming week.

Seaton becomes United’s fifth homegrown signing since September 2009, joining goalkeeper Bill Hamid (Annandale), defender-midfielder Andy Najar (Alexandria), defender Ethan White (Bethesda) and defender-midfielder Conor Shanosky (Sterling).

Hamid and Najar have been regulars in United’s lineup since 2010. White started 21 regular season games as a rookie in 2011 before injuries set him back last year. Shanosky spent 2012 on loan in the second division with the NASL’s Fort Lauderdale Strikers.

Given his age and experience, Seaton seems likely to continue playing in the Development Academy or being loaned to a lower division.
