It was as much in the bag as any round of 59 will ever be.

Jim Furyk, who had never shot lower than 62 on the PGA Tour, started Round 2 of the BMW Championship 11-under through his first 13 holes, meaning that he only needed to play his final five holes 1-under to become the sixth golfer in PGA Tour history to card a round of 59. But just as Tiger Woods proved in his 59 watch at the WGC-Bridgestone Invitational, it’s the final five holes that can be the toughest.

Furyk bogeyed his 14th hole, No. 5 (he started on the back nine), succombing to the weakness that had kept him out of the winner’s circle since his three-victory season in 2010 — his putting.

“It was pretty hectic down the stretch, ” Furyk said after the round. “I hit three good putts on (No. 5), but none of them went in.”

But Furyk bounced with pars on Nos. 6 and 8 and a birdie on No. 7, setting himself up for a dramatic finish on his final hole. If Furyk made a birdie, he’d shoot one of the most memorable rounds in PGA Tour history. If not, he would become yet another golfer to fall short of the magic number.

After a 281-yard drive that split the right-center of No. 9’s fairway, Furyk hit a gap wedge from 103 yards to 3-feet 3-inches. Unlike the short putt that he missed to end the U.S. Team’s chances to win the 2012 Ryder Cup, Furyk buried the straight-in birdie putt in the center of the hole for a 12-under 59.

“There’s not much I could have improved on today,” Furyk said. “So I think I’ll sleep well.”

The lowest score at Conway Farms, other than Furyk’s 59, was 6-under, shot by Jordan Spieth and Jimmy Walker. Furyk’s bogey on No. 5 was the only bogey ever recorded on the PGA Tour by a golfer who recorded a score of 59.

He will start Round 3 of the BMW Championship tied for the lead with Brandt Snedeker at 11-under, three shots clear of the field.
