Troy Merritt remains top of the leaderboard after bad weather cut short the second round of the Barbasol Championship.
Merritt carded a five-under-par 67 to stay two strokes clear before rain halted proceedings in Kentucky on Friday.
The American, who opened the PGA Tour tournament with a 62, had seven birdies and two bogies on day two.
Merritt – searching for his second Tour title and first since 2015 – also hit nine of 14 fairways and 14 of 18 greens in regulation.
Countryman Billy Horschel posted a 66 to be within two shots of the leader heading into the weekend.
Richy Werenski and Tom Lovelady – a stroke further back – were both through 17 holes when officials suspended proceedings for the day.
The pair will resume their second round at 7:30am local time on Saturday.
Shawn Stefani (68), Hunter Mahan (68) and Josh Teater (66) are tied at 10 under through 36 holes.
