David Ousted started half of D.C. United’s matches last season, but after tumbling on the goalkeeping depth chart over the past six months, he finally seems on his way out of Washington. Ousted, 33, reported to the first day of training camp Monday in Washington, but behind the scenes, United continues looking for ways to discard his guaranteed contract worth almost $400,000, an exorbitant sum for an Major League Soccer backup. That salary has scared off potential trade partners and apparently forced United to consider buying him out at the expense of team investors. MLS allows teams to buy out one guaranteed contract per preseason. Such a move clears the corresponding salary cap space. There is also a scenario in which United buys out a portion of his salary, knowing an MLS team has agreed to claim him off waivers and make up the financial difference. Bill Hamid, who supplanted Ousted as the starter last summer after rejoining United from the Danish league, is atop the depth chart.
