Storms sweeping across the East Coast of the US wreaked havoc at the Aronimink Golf Club near Philadelphia with a soaked golf course finally being deemed unfit for Sunday play soon after 2pm local time.
With the chances of Monday play in doubt, the event could yet be reduced to 54 holes with standing as of Saturday evening being confirmed and Justin Rose securing his second BMW Championship title.
Rose, who reeled off nine consecutive pars to finish round three on Saturday after an outward nine of 29, also finished runner-up in this event last year albeit at another venue.
If the tournament is reduced to 54 holes, then three Australians, Cameron Smith 9th, Jason Day 10th and Marc Leishman 29th, would advance to the Tour Championship in 10 days' time.
Leishman birdied his final hole on day three to sneak inside the projected top 30.
