Rain washes out Tuesday's matches in U.S. Open

   Rain canceled Tuesday's day and night sessions at the U.S. Open in Flushing Meadows, N.Y.
   All matches were rescheduled for Wednesday, but the chance of rain is 100 percent then and 60 percent on Thursday, according to weather.com.
   The U.S. Open, which began Aug. 29, is scheduled to end Sunday. However, rain has postponed the men's final until Monday in each of the past three years.
  Americans Donald Young and John Isner, both of whom have won tournaments in or near Sacramento, are scheduled to play back-to-back on the Grandstand court beginning at 8 a.m. PDT Wednesday (ESPN2) as they seek their first Grand Slam quarterfinal berths.
   The unseeded Young, who won the $50,000 Sacramento Challenger in 2008, will take on Great Britain's Andy Murray, the fourth seed and 2008 U.S. Open runner-up. Young beat Murray 7-6 (4), 6-3 in the first round at Indian Wells in March in their only career meeting.
   The 28th-seeded Isner, who won a $15,000 tournament in Shingle Springs in 2007 in his professional debut, will meet France's Gilles Simon, the 12th seed who knocked off 2009 U.S. Open champion Juan Martin del Potro in the third round. Isner and Simon have never played each other.
   Also at 8 a.m., third seeds and defending champions Vania King (Sacramento Capitals) and Yaroslava Shvedova will face eighth seeds and reigning French Open champions Andrea Hlavackova and Lucie Hradecka on Court 17 in the women's doubles quarterfinals.
