Sept 9 (Reuters) - The scheduled final round at the BMW Championship was washed out on Sunday in soggy Pennsylvania.
PGA Tour officials declared the Aronimink course in suburban Philadelphia unplayable as persistent rain fell on an already waterlogged layout.
They postponed the final round until Monday, but with more rain forecast overnight there is no guarantee they will be able to complete the penultimate FedExCup playoff event.
Officials are leaving their options open.
It could become a 54-hole tournament, in which case Englishman Justin Rose would win with his 17-under-par total. (Reporting by Andrew Both in Cary, North Carolina, editing by Ed Osmond)
