The International team couldn’t slow down the United States on Thursday. The United States couldn’t halt the Internationals on Friday. But Mother Nature put them both in their place on Saturday morning, delaying the entire tournament with a blanket of thick fog. The tournament was delayed for well over an hour, restarting at 9 a.m. Eastern.

Fog shut down the proceedings with just two of the day’s four four-ball matches out on the course. The United States’ Scottie Scheffler and Collin Morikawa split the first hole with the Internationals’ Adam Scott and Taylor Pendrith. America’s Tony Finau and Xander Schauffele had only teed off against the Internationals’ Corey Connors and Mackenzie Hughes.

Saturday will also feature foursome matches in the afternoon. Sunday will feature every player in singles matches to determine who wins the Presidents Cup.
