Masters 2016: Live Updates for Leaderboard Scores on Sunday

As the golf world awaits Jordan Spieth's attempt to earn his second green jacket in three tries, the bottom of the 2016 Masters field is getting play underway in Sunday's fourth round.

Former champion Bubba Watson, Sergio Garcia and Adam Scott were chief among the early tee times, playing on an unforgiving Augusta course. This tournament is on pace to have the highest-scoring Masters champion since Zach Johnson won at one over in 2007, which is tied for the worst score to ever bring home a green jacket.

It's unlikely we'll get to that point Sunday. Spieth currently sits at three under with a one-stroke lead over Smylie Kaufman, going three over since carding a 66 on Thursday. With a win he'd become the first player in history to win a major championship wire-to-wire in consecutive years, per ESPN Stats & Info. Still, Spieth concluded his third round with a bogey and a double, putting him in a far more precarious position.

"It was a really tough finish to go from holding a four-shot lead and being in a very similar position to last year, to where all of a sudden now it's anyone's game, so it's tough to swallow that," Spieth said, per Tod Leonard of the Los Angeles Times.

Rory McIlroy currently sits five strokes off the lead after turning in an ugly 77 on Saturday. Playing alongside Spieth, McIlroy did not have a single birdie and carded three bogeys with a double. Spieth's struggles to end his third round give the Northern Irishman a glimmer of hope, but it'll take a big day.

"I just have to make sure that I get off to a fast start, put some red numbers on the board and make a bit of noise to put a bit of pressure on the guys playing behind me," he told reporters. "I'm only five back and I can't believe I am standing here saying that because I was eight behind standing on the 17th tee. I need to regroup and stay positive and go out and attack."

McIlroy currently sits in a tie for 11th, and he'll have a number hoops to jump through before catching Spieth. Perhaps the biggest one of all is world No. 1 Jason Day, who sits at even par for the tournament after a stealthy three rounds. Day's MO has been keeping things simple. He's carded rounds of 72, 73 and 71, wholly unspectacular in the micro but good enough to keep him right on the cusp of contention.

Of course, those rounds were far more wild on a hole-to-hold basis. Day opened the tournament by going 31 on his front nine before giving it all back with a 41 on the back. He has 11 birdies and an eagle so far, but has also carded 11 bogeys and a double. Perhaps only Spieth has hit higher highs this week.

"I'm very pleased with how it went over the last three days, just trying to be as patient as possible and I think it obviously depends on where the leaders are determines on what I'm going to do tomorrow with regards to strategy and trying to press forward from there," Day said, per Omnisport (via Yahoo).

With Hideki Matsuyama, Dustin Johnson and Brandt Snedeker all hanging out around the leader as well, this should be a big day for big names.

Or the likes of Kaufman, Bernhard Langer or Soren Kjeldsen could shock the world and blow things up. Kaufman, 24, is playing in his first Masters tournament and is perhaps the most unlikely top-five contender in recent memory. He only earned his Masters spot after a seven-stroke comeback at the 2015 Shriners Open, and his only previous major experience was being cut at the 2014 U.S. Open.

Langer is a 58-year-old who would shatter the record for the oldest major champion in history. The German won his first Masters in 1985, a year before Jack Nicklaus' historic run at age 46. His steadiness amid difficult conditions has been something to watch.

Kjeldsen is a 40-year-old who has never so much as earned one PGA Tour victory. His last Masters appearance was all the way back in 2010, and he finished 2015 with a cut-cut in the Open Championship and PGA.

In a nutshell: We're looking at two highly dichotomous results here. Either one of the world's best will don the green jacket or Spieth will be tasked with giving up his jacket to a legend or someone we'll all be furiously searching for on Wikipedia later Sunday.
