Targeted allocation money can be applied toward signing or re-signing a player earning more than the maximum budget charge ($436,250) or lessening the impact of such designated players when a new DP is acquired. One source said, however, United was in the market for low-cost depth ahead of the CONCACAF Champions League, which begins this month.
If unused, targeted allocation money carries over to the next season.
United will also receive future considerations from the Timbers, if Seaton’s career takes off.
“Michael is a young player with strong potential who is continuing to grow, and he will benefit from a fresh start,” United General Manager Dave Kasper said. “This deal provides D.C. United with immediate assets and a great deal of future upside.”
“Michael is a talented young player that we believe in time, with our club resources and infrastructure, will continue to develop and be positioned to realize his full potential,” Timbers General Manager Gavin Wilkinson said.
In Portland, Seaton joins Jamaican national teammate Alvas Powell, a 21-year-old defender.
Seaton, 19, made five first-team appearances for United in 2013-14 and spent much of his time on loan with the third-division Richmond Kickers. This year, after recovering from preseason knee surgery, he went on loan to Swedish club Orebro but returned after just two months and five appearances (two starts).
This summer, Seaton was a member of the Jamaican squad that advanced to the CONCACAF Gold Cup final for the first time; his lone appearance came in the waning moments of a 3-1 championship defeat to Mexico two weeks ago in Philadelphia. He is scheduled to join the under-23 team ahead of an Olympic qualifier against Cuba next week.
While Seaton’s Jamaican stock rose, United grew increasingly frustrated with his maturation on and off the field.
Born in Jamaica, Seaton moved to the United States at age 7. He attended Central High School in Prince George’s County, Md., and played for the Bowie-based Freestate Soccer Alliance, a United affiliate, and D.C.’s youth academy.
With dual citizenship, he was enrolled in the U.S. residency program in Bradenton, Fla., years ago but was dismissed for disciplinary reasons.
In early 2013, he withdrew from high school to sign with United, the club’s fifth homegrown acquisition.
United’s other trade this summer came July 16: striker Alvaro Saborio from Real Salt Lake for oft-injured forward Luis Silva.
