Not long after starting play on an already rain-delayed Day 10, officials were forced to stop the action as rain has resumed in Flushing, N.Y.

Today's schedule is jam-packed with great matchups that spilled over from Tuesday's washed out day and night sessions, but the early matches didn't get far before the players packed their bags up and headed back to the locker room to wait out the rain.

On Ashe, Gilles Muller stole an early break from Rafael Nadal to lead 3-0 in the first set before the rain kicked in. On Armstrong, Andy Roddick led a distracted David Ferrer 3-1, and Donald Young and Andy Murray were on serve in the first set, with Young up 2-1.

John Isner and Gilles Simon were originally scheduled as the second match on the Grandstand, but were moved to Court 17 in an unsuccessful attempt to start the match before the rain kicked in.
