Edison: Suspense at the Barclays golf tournament went beyond who would post the lowest score as players and officials were left wondering exactly when the opening event of the FedExCup playoffs would finish.

A long delay due to lightning backed up Thursday's first round, and forecasts of heavy rains and high winds with this weekend's approach of Hurricane Irene raised various scenarios at Plainfield Country Club.

Hurricane-fuelled storms are expected to hit the area late today and further saturate a course that is already soggy from more than a foot of rain last week and another drenching on Thursday.

"If we get five or seven inches [15-20cms] of rain here, we are probably dead in the water," tournament director Slugger White told reporters.

Forecasts expect as much as 30cms of rain.

White ruled out trying to squeeze in 36 holes of golf today even if the select field could get through the first 36 holes by the end of play yesterday and be cut to 70.

"We are not going to do that," White said. "We don't have enough daylight. We can't get it in. Plus, we have not got a very good forecast Saturday afternoon."

Spain's Sergio Garcia, who shot three-under 68 to trail Frazar by four strokes, called it a wait-and-see situation.
