New Zealand's Danny Lee is tied for 15th after three rounds of the latest PGA tour event in Connecticut.
Starting the day tied for 8th, Lee went on to card two bogies and three birdies for a one under par 69 to finish the day at eight under for the tournament.
Hamilton's Steven Alker climbed 10 places into a share of 49th with a third round 68 that put him at four under overall.
Alker is 10 strokes behind the American leader Brian Harman, who rolled in a birdie on his final hole to card his second straight five-under-par 65 for a one-stroke lead.
Harman, whose only PGA Tour win came last year, ended 54 holes at 14-under 196 at the River Highlands course.
Bubba Watson, who led after the first two rounds, posted a 68 and dropped into a share of second with Graham DeLaet (64).
They are tied at 13-under.
"It's always fun to play with Bubba," said Harman. "He was ahead of me at Georgia, so I've always looked up to him. It's great to be in the last group with him, but I will approach it the same way. I'll try to get a good picture on each shot and make some putts. I'm looking forward to it."
Watson held onto his lead with two birdies on the first 11 holes before three-putting the par-4 12th.
