Stewart Cink closed with consecutive birdies on Saturday to take a two-shot advantage after the third round of the Travelers Championship.
The world number five fell into a share of the lead with Heath Slocum following a bogey at the par-three 16th, but recovered to roll in birdie putts at his final two holes to finish off a solid five-under-par 65 which moved him to 15-under overall.
The American has been consistent throughout the year after claiming two runners-up berths, a pair of thirds and six top-10 finishes in 14 events.
“I think if I could get to 20-under tomorrow, I will have given myself a really good chance to win,” said Cink, who finished 14th at last weeks US Open. “So it would be great to get to 20 and finish there.”
Slocum, who is in contention for his first title of the year, signed for a 64 to move onto 13-under.
Kevin Streelman (62), Vijay Singh (64), Tommy Armour III (65), Kenny Perry (65) and defending champion Hunter Mahan (67) all are three shots off the lead.
Streelman, who led after the first round of the US Open, followed up Friday’s 63 with an even better round on a gorgeous day at the TPC River Highlands, carding six birdies and an eagle during his bogey-free round.
