LOUISVILLE Kentucky PGA Championship play was set to resume at 2:40 p.m. (1840 GMT) on Sunday after a weather delay of just under two hours due to water-logged conditions in the final round.
The action was halted just before noon local time as heavy rain swept across the par-71 layout at Valhalla Golf Club, leaving rivers of water on several fairways and pools covering many greens.
That suspension came a little more than two hours before overnight leader Rory McIlroy was scheduled to tee off and ground crews swiftly moved in with squeegees in a mop-up operation.
However, roughly an inch of rain had saturated the course and further thunderstorms have been forecast for later in the day, setting up the likelihood of a Monday finish to the year's final major.
Northern Irishman McIlroy, hunting his fourth major title and second in a row, held a one-stroke advantage overnight at 13-under-par 200 and his tee time for the final round has now been pushed back to 4:19 p.m (2019 GMT).
