Chez Reavie was plodding along during the third round of the Travelers Championship, watching playing partner Zach Sucher extend his lead in Cromwell, Conn.

Then came the turn, both for the round and in the fortunes of the two players.

Coming off a third-place tie last week in the U.S. Open at Pebble Beach, the 37-year-old Reavie matched a tournament record with a back-nine 28 to shoot a 7-under 63. He took advantage of Sucher's problems and turned a 6-stroke deficit into a 6-stroke lead heading into Sunday.

The 2008 Canadian Open winner for his lone PGA Tour title, Reavie had a 16-under 194 total at TPC River Highlands. He birdied Nos. 8, 10-13, 15 and 17-18 and has the largest 54-hole lead in Travelers history.

"Zach got some tough breaks early," Reavie said. "I was able to kind of keep plugging along and make a few putts and the rest was history. I kind of caught fire at the end."

Sucher had a 71 to drop into a tie for second with Keegan Bradley (69) at 10 under.

Silver Lake native Ryan Armour shot a second consecutive 71 and fell into a tie for 34th at 4 under.

Looking for his first PGA Tour win, Sucher — the 32-year-old former college star at Alabama-Birmingham — seemed to have it all going his way, until he didn't.

He took a share of the lead in the last group Thursday night, came into Saturday with a two-shot advantage and shot 31 on the front nine.

But his drive on the 10th hole went left, hit a tree and bounced backward landing in the rough just 154 yards from the tee. He ended up with a bogey on that hole. He needed two shots to get out of a plugged lie at the lip of a green-side bunker on the 11th and ended with a double bogey, and put his ball into two bunkers on the par-4 13th for another double.

It took just a half-hour for Sucher to go from five strokes ahead of Bradley to four strokes behind Reavie.

"Ten was awful and I deserved bogey, but man, three straight holes I hit shots that weren't that far off all behind the lip, so two of them plug and, yeah, rough, that's all you can say about it," Sucher said. "Other than those three holes, it was a great day."

Roberto Diaz (67) and Jason Day (68) were tied for fourth, seven shots back. But Day said he does not think that's an insurmountable deficit on a course where Bubba Watson overcame a six-stroke final-round deficit a year ago.

"There are a lot of emotions that come with Sundays, but I think Chez has been there and won before," Day said. "But every win is different and how you feel is different, so I just try to stick to what I am doing right now, and hopefully, the chips fall my way."

Women's PGA

Hannah Green has a one-shot lead going into the final round of the KPMG Women's PGA Championship and fresh evidence that going after her first LPGA Tour victory at a major won't be easy.

Green three-putted for bogey on the 18th hole at Hazeltine National in Chaska, Minn., for a 2-under 70, leaving her one shot clear of two-time major champion Ariya Jutanugarn, who had a 68.

Green was at 9-under 207 for her first 54-hole lead in an LPGA Tour event. Lizette Salas (68) and Nelly Korda (69) were four shots behind at 5-under 211. Another shot back was Sei Young Kim, who had the low score of the round at 67, and defending champion Sung Hyun Park (71).

Still in the game was Inbee Park (69) at six shots behind. Park won the last LPGA major in Minnesota at Interlachen for the 2008 U.S. Women's Open, her first major in a Hall of Fame career.
