Tiger Woods's hopes of a victorious return from career-threatening injuries evaporated on Augusta Nationals greens on Saturday as Scottie Scheffler led the Masters by three strokes.

Woods, 14 months removed from a car crash that left him with injuries so severe he feared he might lose his right leg, saw his hopes of a stunning comeback for a sixth green jacket come undone with his worst-ever Masters round, a six-over par 78.

The fact that the 46-year-old was even able to tee it up -- and make a 22nd consecutive Masters cut -- was astonishing.

But at nine off Scheffler's lead to start the day, Woods knew he needed something sensational to give himself a chance come Sunday, and instead he posted a round worse than the third-round 77 he shot in his 1996 debut as an amateur.

"It's just like I hit a thousand putts out there on the greens today," said Woods, whose prior mastery of the unforgiving, undulating greens of Augusta helped him to five Masters titles.

"I felt like I didn't really hit it that bad, but I had four three-putts and a four-putt," Woods said. "I just could not get a feel."

Woods's seven-over par total of 223 put him 16 strokes behind Scheffler, who survived drama at the 18th to card a one-under par 71 for a nine-under total of 207.

The 25-year-old Texan takes a three-shot lead over Australian Cameron Smith into the final round.

On a cold, windy day where scores soared, Smith carded the only round in the 60s with a four-under par 68 for 210.

Smith was two strokes in front of third-place South Korean Im Sung-jae, who shot a one-under 71.

But, once again, it was Woods who drew the spotlight.

A three-putt at the opening hole proved a harbinger, a birdie at the second -- where his shot out of a greenside bunker barely missed finding the cup for eagle -- proving only a short respite.

From the fairway at the fifth, Woods left himself 65 feet, and he could only watch in disbelief as his three-foot bogey effort circled the cup and stayed up.

Bogeys at the ninth and 11th followed before he drained a 14-foot birdie at the 12th and two-putted from 27 feet for birdie at the par-five 13th.

The thousands following Woods's every move tried to will him on, cheering and shouting encouragement at every hole, but he closed his round with bogeys at 16 and 17 and another double-bogey at the last.

While Woods acknowledged on Thursday that just making through his first competitive round in 17 months was a victory of sorts, he made it clear he would be looking for better things on Sunday, like getting himself back to even par.

Woods was hardly the only one struggling in the blustery conditions, where the scoring average was 74.5 shots and only seven players were under par for the tournament after 54 holes.

Ireland's 2019 British Open champion Shane Lowry and 2011 Masters winner Charl Schwartzel both carded one-over par 73s to share fourth place on two-under 214.

Scheffler was 10-under through 17 holes when his tee shot at 18 ended up in dense undergrowth left of the fairway.

It took a concerted search to find his ball and after wading into the bushes to see the situation he took and unplayable lie, belted a shot up to the green and limited the damage to a bogey.

"We saw the guy who always finds the balls kind of panicking. I thought, 'Oh crap,'" Scheffler said.

"Just getting it out of the bush and trying to make my five was key," added Scheffler who said his heart rate "went up when they couldn't find the ball but it went back down when they found it."

It was a dramatic end to a round that featured half a dozen birdies and five bogeys, Scheffler maintaining his air of methodical calm throughout.

Smith, who finished tied for second behind Dustin Johnson in 2020, when he became the only player to shoot four rounds in the 60s at the Masters, said playing within himself in the challenging conditions was the key to his round.

"I didn't try to smash any drivers off the tee. I just tried to give myself opportunities," said the Aussie, who added the toughest part of the day for him was "keeping my hands warm."

"It was brutal. I think off the tee with this west wind there's not many holes you get straight downwind or straight into the wind.

"You get lots of crosswinds and can get quite tricky into the greens and hitting different shapes and trying to judge the wind as well."
