Scottie Scheffler and Rory McIlroy, Nos. 1 and 2 in the Official World Golf Ranking, respectively, will be competing in the Travelers Championship. Scheffler is the defending champion, having defeated Tom Kim in a playoff following a climate protest during the final hole of regulation.

OAKMONT, Pa. — As Phil Mickelson, aka Lefty, aka Phil the Thrill, aka FIGJAM, aka one of the two most famous golfers of the 21st century, teed off Thursday in what might be his final U.S. Open, there were more security guards than journalists following him. And there were two security guards.

All three were between seven and eight shots behind the leader, and all were in danger of being cut Friday. The U.S. Open remains golf’s cruelest test.
