Better weather is hoped to let play forge ahead on the second day of the 2010 Ryder Cup.
Golf’s biggest tournament, being held in Wales for the first time, was delayed by torrential rain less than two hours after tee-off on Friday.
A changed schedule sees all 24 European and USA players on the greens as the forecasters predict clearer skies above the Celtic Manor Resort in Newport.
Organisers hope to avoid having to run into an extra day for the first time.
Play resumed at 1700 BST on the first day, leaving the visitors, and defending champions, ahead in two games, but only after both sides were forced back to the clubhouse for more than seven hours.
The venue’s drainage network and teams of greenkeepers allowed the contest to continue shortly after the deluge had finished.
Big crowds turned up on the opening day and up to 45,000 spectators are expected on the site daily over the weekend.
Fans with tickets to Sunday’s play are being asked to present them on Monday if play goes in to a fourth day.
The tournament is not giving refunds on tickets.
The event will have to end at sunset on Monday, whatever the weather.
The captains have an agreement that the matches cannot continue any longer than when the sun goes down on Monday, which is at 1843 BST.
If the 28 matches are not completed by then, the results of all the completed matches will stand. Any match not finished and still on the course would be declared a halve no matter what the score.
If the contest, the 38th biennial event, is forced to carry over to Monday, it will be the first time in its history that the competition has been held over four days.
The heavy rain has already claimed a victim in the US side – the team’s waterproof gear.
A number of players were forced to buy new sets from the club shop after their own sprang leak, meaning they may no longer be in matching outfits when play resumes.
The tournament alternates between Europe and America and has an estimated television audience of 600m homes in 185 countries.
