LOUISVILLE, Ky. (AP) — Now that the rain has cleared out, fog has moved in at the PGA Championship.

Thick fog covered Valhalla on Saturday morning, delaying the resumption of the second round and forcing tournament organizers to play threesomes off both nines for the third round.

Xander Schauffele has a one-shot lead over Collin Morikawa after 36 holes, with Masters champion Scottie Scheffler three shots back as he tries to clear his head and get back into a routine following the wildest day of his career.

Scheffler was arrested early Friday in a predawn incident with Louisville Metro police, who were investigating a fatal traffic accident involving a pedestrian. Traffic was blocked outside the gates when Scheffler tried to ease his way into the club.

Police say he ignored directions and an officer was dragged to the ground by Scheffler’s car. He was arrested on a felony charge of second-degree assault of a police officer and three other lesser charges, booked into jail and made it back for his tee time with under an hour to spare.
