WASHINGTON (AP) — A postponed game between the Houston Dynamo and D.C. United has been rescheduled for July 22. The Dynamo and United played only a few minutes of the first half at RFK Stadium on June 4 when thunderstorms forced officials to abandon play for the evening. The makeup date was chosen in part because the Dynamo will already be in town. The teams are scheduled to meet in a SuperLiga match at RFK on July 19.
