He was at 13-under 200 and will be paired in the final group with longtime friend Stricker, who holed out for eagle from the 15th fairway and had a 64.
Brandt Snedeker, tied with Furyk to start the third round, got up-and-down from behind the 18th green for birdie to get back to even-par 71 for the day and remain in the hunt just two shots behind.
And very much in the picture was Tiger Woods, who made it through the day without any drama.
Woods still objected to the two-shot penalty he was given after his second round for his ball moving ever so slightly as he tried to remove a small stick next to it. And he played before a massive crowd with Sergio Garcia, their first time together since Garcia ended some verbal sparring by jokingly saying he would have Woods over for dinner during the U.S. Open and serve him fried chicken.
In the suburbs north of Chicago, there was hardly any heckling beyond what is heard at a normal golf tournament in America.
Woods ran off six birdies in seven holes and at one point got within two shots of the lead until his momentum was stalled with a par on the par-5 14th and a bogey on the 15th hole after driving his first shot into the water. He still had a 66 and was only four shots behind.
"I had a nice little run,'' Woods said.
Of the five previous 59s on the tour, only two failed to win the tournament Chip Beck in the 1991 Las Vegas Invitational and Paul Goydos at the 2010 John Deere Classic. Beck tied for third. Goydos was runner-up.
Al Geiberger shot 13-under 59 in the second round of the 1977 Memphis Classic and went on to win. David Duval (13-under 59 at the 1999 Bob Hope Classic) and Stuart Appleby (11-under 59 at the 2010 Greenbrier Classic) shot their rounds on Sunday to win.
Furyk and Snedeker made quick retreats in the early going before Furyk got back on track. He built a two-shot lead with a short birdie on the 15th hole, but he drove into the rough on the 18th, laid up in the rough and ran his 30-foot birdie putt some 5 feet by the hole. He missed the par putt and watched his lead shrink to one.
Furyk has struggled closing out tournaments over the last few years. He had a one-shot lead in the U.S. PGA Championship, losing to Jason Dufner last month at Oak Hill. A year ago, he had at least a share of the 54-hole lead in three tournaments and failed to win.
