AUGUSTA, Ga. -- Both golfers who'll be in the final pairing of a suddenly scintillating Masters have been through all of this Augusta National-on-Sunday excitement before.

Bubba Watson did it in 2012, when he won the green jacket in a playoff. And Jordan Spieth did it often in his imagination while practicing putts as a kid -- which wasn't all that long ago.

That is only half of the story, because Watson failed to extend his second-round lead and fell back to 5 under par, bringing a big crowd into contention.

Thirteen players -- including four major champions -- are somewhere between 5 under and 1 under, poised to test the adage that the Masters begins on the back nine on Sunday.

"I'm 20 and this is the Masters, this is the tournament I've always dreamed about," said Spieth, who shot a poised 2-under 70 on Saturday to get to 211 and will start Sunday tied with Watson. "As far as being patient, shot-to-shot, I think I've done the best that I ever have with my mental game."

With a win Sunday, Spieth would become the youngest champion in Masters history. He knows enough about that history to realize how hard it will be. He prepared for it by hitting pitch shots in his yard and pretending to win the Masters when he was learning the game at Brookhaven Country Club in Texas. Spieth was savvy enough to seek advice from fellow Texan Ben Crenshaw, a two-time winner here, and Crenshaw's caddie Carl Jackson, who has carried in 53 Masters.

"I was going to buy a T-shirt for (my caddie) that says, 'Carl Says,' because he keeps saying that to me out there," Spieth said.

Watson can rely on his own experiences -- the ones from two years ago, more than the ones from Saturday. He did eagle the second hole to go 8 under and birdied No. 10, to get back to 6 under. But his putting stroke was not as confident as it had appeared during the first two rounds. He shot 2-over 74, with pars on the par-5 13th and 15th feeling like bogeys for a big hitter like him.

"You have to keep looking at where you're at. You're still winning so you can't get down," he said. "If you're going to get down when you're still winning, then you've got issues. And I do have issues, but ..."

He smiled when he said that. He also insisted he won't be uneasy waiting to tee off at 2:40 (local time) -- after the likes of Matt Kuchar and 2012 Frys.com Open champion Jonas Blixt (4 under) and Rickie Fowler and Miguel Angel Jimenez (3 under).

"You always have that dream as a kid," Watson said. "So when you get here, you hear the same roars and you want to be part of those roars. On Sunday, that's a big deal because that's the day they give out the green jacket ... I've won one, so I've got that going for me. If I play bad tomorrow, I still have a green jacket."

  • A week before making his debut on the Champions Tour, Jimenez shot a 6-under 66. The 50-year-old Spaniard had seven birdies against a lone bogey. "I have plenty of victories in my career, and having a major in my career would be amazing," Jimenez said. "That would be the flower on top, to say so."

  • Defending champion Adam Scott three-putted twice in the first four holes and tumbled down the leader board. He needed 35 putts to get through the third round and finished with a 4-over 76 that left him 1 over for the tournament. "It's not the end of the world," he said. "It would be fun to post a number and sit in the clubhouse and watch."

  • Fred Couples goes into final round four shots off the lead and a long shot by anyone's estimation at the age of 54. "I'm playing pretty good golf and I have a shot tomorrow of shooting some silly round to maybe win, but it's going to take a 65 or 66," said Couples, who shot a 1-over 73.

  • Gary Woodland matched the lowest score ever on the front nine with a 6-under 30 and got to 7 under with another birdie at 10. "It was a zone that you want to be in, and hopefully I get back in that zone tomorrow," said Woodland, who admittedly had to catch his breath as he walked to the 11th tee. But he bogeyed 11 and double-bogeyed 12. He birdied 13 but struggled down the stretch and settled for a 69 that left him at even-par 216. "I need some help from the guys in front of me," he said.

    YOUNGEST MASTERS WINNERS
    Co-leader Jordan Spieth, 20, is in position to become the youngest Masters champion. Here's a look at the three youngest winners:
    Tiger Woods, 1997, 21 years old
    Woods won his first major tournament in dominating fashion, winning by 12 strokes and becoming the event's first black champion.
    Seve Ballesteros, 1980, 23
    The Spaniard became the first European to win the major (he won by four strokes), and then added a second title at Augusta in 1983.
    Jack Nicklaus, 1963, 23
    Nicklaus held off Oakland native Tony Lema by one stroke for the second of his record 18 major titles. His first major title was the 1962 U.S. Open.
