There's no shortage of storylines among the players in the hunt.
Experience matters at Augusta National and Couples, who won his Masters Green Jacket 25 years ago, before 2015 victor Jordan Spieth was even born, put his knowledge to good use carding a two-under 70 to feature on the midway leaderboard just three strokes off pacesetters Sergio Garcia, Charley Hoffman, Thomas Pieters and Rickie Fowler.
And that's only the start. The 2015 Masters champion vaulted up the leaderboard Saturday, shooting a four-under-par 68 to put him into a tie for fourth place. Missing numerous birdie chances on the front nine, the Spaniard shot four birdies and two bogeys to maintain his spot at the top of the leaderboard.
"There's wonderful storylines. Obviously I'm a major champion, but I'm looking for more and I'm certainly looking for my first Masters and my first green jacket", said Rose, who made five of his seven birdies between the 12th tee and the clubhouse. I feel good about everything. - Jason Day, who played with Augusta National member Jeff Knox because he was the first player off Saturday morning and is not allowed to play alone. Saturday's round began with a logjam near the top and, while some of the names are different, not much is different in terms of how close the players are to one another.
At even par are three past champions in Phil Mickelson, Adam Scott and Jordan Spieth, all capable of grabbing this event by the throat over the weekend.
Charley Hoffman made a couple of early birdies Saturday to break the four-way tie from the start of the day. They are at 6-under-par 210 for 54 holes.
Lurking menacingly alongside compatriots Hoffman and Ryan Moore on 4-under is Jordan Spieth, who enjoyed an extremely productive "Movers Day".
The mistake was eventually rectified by tournament officials and Garcia, who has 22 top-10 finishes in majors, also bogeyed the 13th before picking up shots on the 15th and 17th in a 71.
Hoffman shot a 7-under 65 on Thursday to take a four-stroke lead.
"After the first round (75), I couldn't ask for much better than this", Spieth said after the third round.
"Might free me up a bit, being behind", Spieth said. And if I don't, then so be it. "So I guess at the end of the day, you try to not think about those and try to be as positive as possible".
Rory McIlroy of Northern Ireland, drops his putter on the 13th hole during the third round of the Masters golf tournament Saturday, April 8, 2017, in Augusta, Ga.
"I want to give myself a chance for that to be enough".
"It's not easy, because it's always. having a chance to win a tournament is always exciting", Garcia said of controlling his nerves as he chances that elusive major title. "Just make sure we have a good chance coming into the last five or six holes, and see what happens". "Not with regards to the actual shots itself into the greens, but more so once you get on the greens they're starting to become a lot firmer and faster and you have to have really, really nice touch because pin locations are tough". "It's honestly something I still think about every day".
