Australian Cameron Percy faces an anxious wait with play in the final round of the PGA Tour's Barbasol Championship suspended until Monday (Tuesday AEST) due to thunderstorms.
Sunday's third stoppage of play at Champions Trace at Keene Trace Golf Club came with the four leaders - Hunter Mahan, Robert Streb Tom Lovelady and Troy Merritt at 18-under par - and four other contenders waiting to begin the round.
Percy is just two shots off the pace.
Lightning caused one delay, and play was stopped earlier in the afternoon to clear water that accumulated on the course following a morning of steady and sometimes-heavy rain.
Inclement weather has plagued the tournament throughout the weekend. The second round was completed Saturday morning after being suspended by thunderstorms late Friday afternoon.
The resumption will mark the PGA Tour's second Monday finish this season. Jason Day won the Farmers Insurance Open in January after darkness delayed the sixth playoff hole, and he needed just 13 minutes to claim the victory.
