What began as a 14-day marathon has turned into a sprint to the finish for the players still left in the main draw of the 2006 US Open.
"The only thing that is tough is that whoever ends up winning they could play many matches in a short amount of time," fifth seeded American James Blake said.
Top seed Roger Federer of Switzerland, had his fourth round match postponed and now highlights a full Wednesday schedule at the Billie Jean King National Tennis Center.
Rain washout all but one match Tuesday and has resulted in a total of six cancelled sessions at the USD 18.5 million event.
In order to win his third straight US Open title, Federer would have to win four matches in five days.
He is also seeking to extend his winning streak to 17 matches when he takes on Marc Gicquel, who is competing in his first US Open. At age 29, France's Gicquel is the oldest player left in the men's draw and is a heavy underdog against world number one Federer.
Former champion Marat Safin of Russia is in one of two matches that need to be completed after carrying over from Wednesday.
Safin was up 2-1 and on serve in the first set against Germany's Tommy Haas when rain sent the players to the locker room.
In the other unfinished match, Scotland's Andy Murray was trailing Russian seventh seed Nikolay Davydenko 6-1, 5-7, 6-3 when play was stopped.
