A 12-under 198 total still left Koepka within sight of his third major title in 14 months, but the two-times U.S. Open champion's grip on the Wanamaker Trophy had loosened.
Koepka blew out the U.S. Open field at Erin Hills a year ago with a record-tying finish of 16 under, this after his short-game coach got right up in his face on the range and told him, "You're no good". The Australian is tied with Woods at 11 under as he tries to win for the first time in two years.
Being unable to score on the back nine has been a constant for Woods all week.
Birdies were not only everywhere, but necessary to stay in contention, and Spieth knew it, particularly at 17 - a par 5 where eagle is in play and birdie is a must.
Wimbledon glance: Williams to face Goerges in semifinals
Williams is seeded 25th after returning from having a baby, but is looking like her usual dominant self on the grass courts. No. 7 Karolina Pliskova became the last of the top-10 seeds to be knocked out, losing to Kiki Bertens of the Netherlands.
Brooks Koepka, taking full advantage of soft conditions and his own casual power, took a grip of the event as he reached the turn in 30 strokes and subsequently opened a five-stroke lead.
It looked curtains when a par putt horseshoed agonisingly out at the 14th but back came Woods with a tap-on birdie at the 15th. "I played 29 holes, made - I think I dropped three shots today and two of those were 3-putts". Behind him, Koepka holed his two birdie putts.
"I told myself exactly that on 11 tee", Woodland said of his triple in Phoenix.
Sunday's play will decide the victor of the fourth and final major of the golfing season with the PGA Championship itself moving to a May date for the 2019 season. That's just the nature of the way it's playing right now.
Koepka never imagined a year like this. But he answered with four solid rounds at Bellerive, capped by a 69 Sunday that left him with a top-20 finish, while closest pursuers Bryson DeChambeau and Phil Mickelson missed the cut.
Garcia's form a concern ahead of Ryder Cup
Very much like McIlroy, Day falls into the "due a big win" category and recent fine form suggests it could come at Bellerive. At Wisconsin's Whistling Straits course, Day became the first major victor to finish with a 72-hole total of 20-under-par.
He now is No. 2 in the world, with a shot at overtaking Johnson in two weeks when the FedEx Cup playoffs start.
The four-time PGA Championship victor made five birdies and one bogey through eight holes and finished with 10 consecutive pars.
The 42-year-old looked certain to end a string of pars when he fired a superb approach into the par-five 17th, only to charge the eagle attempt four feet past the hole and miss the return.
Fleetwood signed off with a 68 for tied 36th place.
"It's been a pleasure to play in front of them, it really has", Woods said.
Loesch Slams Dems for 'Shameless Fearmongering' About Trump SCOTUS Pick
Republicans hope to have Kavanaugh confirmed by the start of the court's session in October, and before the midterm election. Hatch said on PBS that Kavanaugh should have an easier time than Justice Neil Gorsuch had past year , "but I don't know".
While it's going to be a hard task for Woods to claim a 15th major win this week, it's not out of the question.
