GSTAAD, Switzerland (AP) _ Incessant rain left the $600,000 Swiss Open in hot water Friday, wiping out another day of play and leaving the tournament dangerously backlogged.

With the second round still unfinished, players will contest up to two matches each on Saturday to complete the quarterfinals, with the semifinal and final both scheduled for Sunday.

The steady rain kept top-seeded Alex Corretja from completing his second-round match against American Vincent Spadea. Corretja, the 1998 champion, was leading Spadea 6-2, 5-2 Thursday when rain interrupted play.

The opening day Monday was completely washed out and only eight matches were played the next two days, leaving the tournament badly behind schedule and forcing organizers to borrow a couple of courts from the nearby Palace Hotel.

Thursday was the only day which was relatively unaffected by the rain, and organizers were able to cram in 11 singles matches, with some players squeezing in both first- and second-round matches.
