Players will return to complete the final round of the Barbasol Championship on Monday after bad weather wreaked havoc again.

A thunderstorm in the area forced Sunday's final round to be suspended in Kentucky.

Co-leaders Hunter Mahan, Robert Streb, Tom Lovelady and Troy Merritt were yet to tee off when play was abandoned.

The PGA Tour tournament, which has been plagued by bad weather, will resume at 7:30am local time, with the quartet a shot clear at 18 under.

Ben Silverman is a stroke behind having been through 10 holes, while Sam Ryder, Blayne Barber and Billy Horschel – also 17 under – were waiting to open their rounds.
