(Reuters) - A blistering back nine saw Chez Reavie romp to a six-stroke lead in the third round of the Travelers Championship in Connecticut on Saturday.
Six back at the turn, Reavie birdied seven holes coming home to shoot a seven-under 63 as he took aim at his first PGA Tour victory in 11 years.
His 16-under 194 put him comfortably in front of Keegan Bradley (69) and Zack Sucher (71) at TPC River Highlands.
Sucher, the second-round leader, blew a five-stroke lead with a bogey, double-bogey, double-bogey start to the back nine.
Reavie, who tied for third in last week's U.S. Open, played the final nine holes in a course-record tying 28, 12 strokes better than Sucher.
Australian Jason Day (68) and Mexico's Roberto Diaz (67) shared fourth at nine-under.
Bryson DeChambeau (64) and Kevin Tway (66) were in a group of four at eight-under that also included England's Tommy Fleetwood (67) and Scotland's Martin Laird (68).
World number one Brooks Koepka stumbled home with a two-over 72, recording four birdies, four bogeys and a double that left him 15 strokes adrift of Reavie.
Defending champion Bubba Watson spiraled downward as well with six bogeys in a round of 73 that put him 14 shots behind at two-under for the tournament.
