Why was play suspended in Round 3 of the 2025 ISCO Championship?

The third round of the ISCO Championship was in progress on Saturday, July 12, before the PGA Tour was forced to suspend the event due harsh weather conditions. The event is happening at Hurstbourne Country Club in Louisville, Kentucky, parallel to the Genesis Scottish Open in North Berwick, Scotland.

PGA Tour Communications announced the reason for the suspension amid the third round of the ISCO Championship via X. The organizers took the decision amid extensive lightning around the golf course.

"The third round of the ISCO Championship is suspended at 1:24 p.m. ET due to lightning in the area."

In the weather forecast shared by the PGA Tour Communications earlier, there was a threat of rain showers and storms hanging over throughout the day. Though the probability of showers was low earlier in the day, clouds were predicted to remain throughout.

The chances of the showers and storms were likely to increase as the day progressed. But, the delay due to lightning came as a surprise to the players and organizers.

Here is the weather forecast shared by the team before the third round commenced:

"Saturday’s weather forecast for the ISCO Championship."

Chan Kim has maintained the lead from Round One with an impressive 11-under par score after two rounds. Three players - Vince Whaley, Kristoffer Ventura, and Thomas Rosenmüller were tied for the second position with a 6-under par score heading into the third round.
