US Open Golf 2015: How to View Live Leaderboard Scores, Updates on Sunday

Through 54 holes, four different golfers hold a share of the lead at the 2015 U.S. Open at Chambers Bay. The final round certainly won't be lacking in excitement as a champion is crowned Sunday.

You can view the leaderboard below. It will update continuously throughout the day to reflect the current standings:

It's extremely rare that the U.S. Open 54-hole lead is shared four different ways. According to the PGA Tour, the last time was a little over four decades ago:

Among the quartet, Jason Day will likely be the sentimental favorite.

The 27-year-old has certainly had a crazy past few days. He became dizzy and fell on the ninth fairway Friday and followed it up with a two-under 68 on Saturday.

Between his vertigo and the medications he was taking to deal with said vertigo, Day clearly wasn't himself in Round 3, and he said as much after the round, per USA Today's Christine Brennan:

"

I didn't feel that great coming out early and then I felt pretty groggy on the front nine just from the drugs that I had in my system, then kind of flushed that out on the back nine. But then it kind of came back — the vertigo came back a little bit on the 13th tee box, and then I felt nauseous all day. I started shaking on 16 tee box and then just tried to get it in, really. Just wanted to get it in. I really gave it all I had out there.

"

The fact that Day still managed to get into a tie for first despite all of those obstacles is a testament to his talent and determination. Should he win the U.S. Open, it may be one of the more impressive victories of all time.

Either way, he already has the respect of fellow Tour pros like Billy Horschel:

As much as Day winning the tournament would make for a great narrative, American golf fans would likely settle for Jordan Spieth or Dustin Johnson taking home the title.

For Spieth, a second major tournament win would be more affirmation of his prodigious talent. Capturing a Masters and U.S. Open by the age of 21 is a monumental accomplishment, should Spieth pull it off. He, however, has a different perspective on things, per Fox Sports 1's Jason Gay:

Johnson, meanwhile, is still looking for his first major win. The 30-year-old looked to be the next American golf star back in 2010, but the promise never materialized as much as many had hoped. Johnson has a handful of top-10 finishes to his name at major tournaments but no victories.

As if that's not enough of a weight on Johnson's shoulders Sunday, he'll also look to make amends for his disastrous finish to the 2010 U.S. Open.

Like he is now, Johnson sat atop the leaderboard after 54 holes at Pebble Beach. With a three-shot cushion over Graeme McDowell, he looked poised to go all the way.

In the final round, Johnson completely collapsed, shooting an 11-under 82 and winding up in a tie for eighth.

Branden Grace is a major wild card in all of this. He has never won a PGA Tour event in 37 tries and has finished in the top 10 just twice. His European Tour record is much better: six wins dating back to 2012.

As Golf Channel's Bailey Mosier alluded to, Grace's performance may have a big say on what fans first think about when recollecting the 2015 U.S. Open:

If you had to bet, you'd guess the eventual winner will be one of Grace, Johnson, Spieth or Day. A three-shot lead is fairly significant with the way Chambers Bay has played this weekend.

It would be one thing if just one guy had a three-stroke advantage on the closest golfer(s). With four guys all at four under, the chances they all collapse and open the door for the rest of the field seem remote.
