Denny McCarthy came inches from shooting a 59, settling for a 10-under 60 for the lowest round of his PGA Tour career, and Rory McIlroy made his first ace on tour on a day of low numbers at the Travelers Championship. Keegan Bradley and Adam Scott also made runs at golf’s magic number but faltered late. Each shot 62 at the TPC River Highlands, where Jim Furyk set the PGA Tour record with a 58 in 2016. Scottie Scheffler, the No. 1 player in the world, finished with a 7-under 63. McCarthy started on the back nine. He had five birdies on his first six holes and five more coming in.
