New York: His match, and his retirement, put off for at least another day, Andy Roddick stepped out of Arthur Ashe Stadium and into the drizzly night, a black jacket's hood pulled overhead, a bag of ice soothing his right shoulder.
He'll try to prolong his US Open — and his professional tennis career — on Wednesday.
Roddick's fourth-round showdown against another past champion at Flushing Meadows, Juan Martin del Potro of Argentina, was suspended because of rain Tuesday night, with the American leading 1-0 in a first-set tiebreaker.
Other matches stopped in progress includes defending champion Djokovic against Wawrinka and Tipsarevic against Kohlschreiber.
A little more than a half-hour later, the players were told they could head to their hotels.
They were scheduled to resume Wednesday as the second match in Ashe, after four-time major champion Maria Sharapova's quarterfinal against 2007 Wimbledon runner-up Marion Bartoli. That was halted on Tuesday with Bartoli ahead 4-0.
Other matches stopped in progress, also in the first set, included defending champion Novak Djokovic against No. 18 Stanislas Wawrinka, and No. 8 Janko Tipsarevic against No. 19 Philipp Kohlschreiber.
On a day of off-and-on action because of intermittent showers, only two singles matches were completed: Top-seeded Victoria Azarenka reached her first US Open semi-final by cobbling together a 6-1, 4-6, 7-6 (5) victory over defending champion Sam Stosur, and No. 4 David Ferrer reached the quarter-finals by beating No. 13 Richard Gasquet 7-5, 7-6 (2), 6-4.
