The Georgia product’s solid performance got him to 17-under 196 for the tournament at TPC Deere Run. Three-time winner Steve Stricker is alone in second, one stroke better than Scott Brown heading into the final round.
Tim Clark, Jerry Kelly, William McGirt and 2012 champion Zach Johnson are three back at 14-under 199. Clark shot a 64 to move into contention.
The 27-year-old Harman has never finished better than third on the PGA Tour, but he played quite well in the third round. The lefty hit 17 greens and 12 of 14 fairways.
Harman bogeyed Nos. 12 and 18, the latter by missing the green with his approach. His eagles came from 30 feet on the par-5 second and from 47 feet on the par-5 17th.
Stricker finished strong for a 7-under 64. He had his streak of bogey-free holes end at 24 with a 5 at the par-4 11th, but rallied for birdies on the last two holes.
Brown matched the lowest PGA Tour round of 2014 with his 10-under 61. On a day when players were allowed to clean their ball in the fairway because of an early morning downpour, he flirted with a 59, but had to settle for birdie on the par-5 17th after reaching the green in two shots, and then parred the par-4 18th.
U.S. Senior Open: Gene Sauers shot a 3-under 68 on Saturday to take a three-stroke lead in the third round.
Sauers, a Savannah native who played at Georgia Southern, had a 33 on the back nine to take control at Oak Tree National heading into the final round today. He is at 7 under for the tournament.
Colin Montgomerie, Bernhard Langer and Scott Dunlap are tied for second at 4 under.
Langer, who has dominated the Champions Tour all season, was solid, but had several potential birdies lip out during his even-par 71.
Marco Dawson, who shot a 76 on Friday, rebounded with a 69 on Saturday and is tied for fifth with Jeff Sluman and Vijay Singh.
Scottish Open: Justin Rose set up a chance to capture back-to-back titles by shooting a 5-under 66 to move into a share of the lead with home hopeful Marc Warren after three rounds.
Rose and Warren (67) are on 10-under-par overall at the warm-up tournament for the British Open, one shot clear of Kristoffer Broberg of Sweden (68).
Nearly three weeks after winning the Quicken Loans National at Congressional to end a yearlong drought, Rose has kept up his strong form despite struggling with hayfever and, more recently, sinus pains.
Conditions were much more benign compared to Friday, but Rory McIlroy (68) and defending champion Phil Mickelson (70) were unable to mount considerable challenges to the leaders and are seven and eight shots off the lead, respectively.
Ollie Schniederjans, the Cobb County native, Georgia Tech star and top-ranked amateur, shot 72 and was even-par for the tournament.
Women’s British Open: A late ruling took Inbee Park from one shot behind to leading the way Saturday, the slightest head start in her quest to become only the seventh player to win four of the LPGA Tour’s major championships.
Park handled the tough opening stretch at Royal Birkdale with three birdies and shot a 4-under 68, giving her a one-shot lead over fellow major champions Suzann Pettersen of Norway (68) and Shanshan Feng of China (69), along with Ahn Sun-Ju of South Korea.
Ahn appeared to be the player to chase after what she thought was a 69 for a one-shot lead.
She was summoned to the rules trailer, where officials determined she used her left foot to build her stance in a pot bunker left of the 18th green. Ahn was assessed two shots for violating Rule 13-3, Her par turned into a double bogey and her 69 became a 71.
The penalty also created a wide-open final round at Royal Birkdale. Park was at 4-under 212, though a dozen players were within three shots of the lead.
