England's Tommy Fleetwood will take a three-shot lead into the final round of the Travelers Championship in Connecticut.
The 34-year-old, looking to clinch his first PGA Tour title, had a share of a three-way lead after the second round.
A brilliant seven-under-par 63 on Saturday has given Fleetwood the outright lead over American pair Russell Henley and Keegan Bradley.
Henley catapulted into contention with a blistering nine-under-par 61 that included four birdies in his first six holes.
The American set a clubhouse score of 13 under but Fleetwood got to 14 under with an eagle on the par-five 13th.
A birdie on the 15th followed and Fleetwood came close to finishing his round by picking up another stroke.
While world number one Scottie Scheffler slumped to a two-over 72, world number two Rory McIlroy shot a two-under 68.
The Northern Irishman made four bogeys across the front nine but a double bogey on the 12th probably ruined his hopes of a late charge on Sunday.
