Max McGreevy holds a one-stroke lead at the Barbasol Championship, sitting on 17-under after a rain-interrrupted Saturday caused havoc during the third round.

Heavy rain in Kentucky has meant tournament organisers at Keen Trace have had to work around the conditions, and it only continued on Saturday, with staff even trying to empty the puddle-filled bunkers with buckets at one stage.

The final groups only started their rounds at 7:20pm local time, but were only able to get through three holes before darkness suspended play again.

Leading at the start of the day's play, Matti Schmid sits one stroke from McGreevy, and Adam Svensson moved level with him following a birdie on the par-three second hole.

Ricardo Gouveia remained a further stroke back on 15-under while Sean O'Hair took advantage of the softer conditions, moving to 14-under after three birdies in the opening four holes.

O'Hair is tied with Kevin Streelman and Trey Mulinax, with third-round play scheduled to resume on Sunday morning.
