Martin Kaymer has been absolutely dominating the field at the 2014 U.S. Open from Pinehurst No. 2, but will he continue to do the same over a pressure-filled final 18 holes on Sunday?
That's the question on everyone's mind as this prestigious tournament approaches its final day.
Kaymer was solid on a difficult Saturday, but we also saw some promising surges from Rickie Fowler and Erik Compton.
If you're out and about while Kaymer attempts to cling to his five-shot lead, here's a quick look at the updated 2014 U.S. Open leaderboard:
As the final pair awaits their 3:35 p.m. ET tee time, let's take a look at the top storylines to watch during Sunday's final round.
Top Final Round Storylines
Will Kaymer Hang On?
This is the obvious storyline for Sunday.
Kaymer has a chance to make history—in an unfortunate manner. Here's a look at what he's up against, according to a tweet from Trey Wingo of ESPN:
Well, Kaymer had a six-stroke lead through 36 holes, and he still has a five-shot lead heading into the final 18 holes.
Since a player hasn't lost at least a four-stroke lead since 1909, Kaymer could become the first golfer to do so in over 100 years should he falter on Sunday.
That's certainly not the record he's looking to bring home to Germany.
Can the Improved Fowler Make Some Noise?
Since Rickie Fowler began working on swing changes with coach Butch Harmon, he's been rather inconsistent on tour.
Well, that appears to have changed in a big way during the U.S. Open.
Fowler has been extremely consistent, recording a pair of 70s, followed by a three-under 67 on Saturday, to earn a spot in Sunday's final pairing with Kaymer.
According to ESPN Stats & Info, Fowler's 67 on Saturday is a good sign for the young golfer:
If anyone appears to have a solid chance to give Kaymer a run for his money, it will be Fowler.
Fowler understands his position behind Kaymer but seems ready to continue focusing on his own game, according to a tweet from PGA Tour:
If Fowler keeps playing his own game, and Kaymer stumbles on Sunday, we could very well be in for a rather exciting finish.
Will Mickelson Find His Game?
Things haven't exactly been going smoothly for Lefty recently.
Phil Mickelson fell to No. 11 in the world golf rankings after several missed cuts and just one top-10 finish this season.
Through three rounds at Pinehurst No. 2, Mickelson has yet to break par and is five over heading into Sunday.
Although he hasn't recorded a double or worse, he ranks just T31 with 11 total bogeys through 54 holes. Known very well for his stellar short game, it's been Mickelson's flat stick that's failed him recently.
He's changed his grip more than once recently. PGA Tour noted how briefly he used the claw during tournament play:
After a decent round on Saturday, Mickelson did think he putted better, according to a tweet from Golf Central:
That's a promising sign for Lefty; however, he has quite a way to go if he is to regain his old form and compete at the highest level once more.
Could we see a surge from Mickelson during the U.S. Open's final round?
That's certainly something to watch for.
