10:32PM: The conclusion of the 115th U.S. Open:
10:22PM: In case you were wondering ... Spieth confirmed he did not have a fifth outfit had he needed to play an extra 18 on Monday.
10:17PM: Dustin Johnson misses his eagle attempt from 12 feet, 4 inches. Misses his 4-footer coming back. Jordan Spieth is your U.S. Open winner.
10:09PM: DJ knocks it close for eagle. If he makes it, he wins the U.S. Open. A two-putt birdie would mean an 18-hole Monday playoff with Jordan Spieth.
10:07PM: Birdie for Spieth. Jordan is in the clubhouse with the lead, but Dustin Johnson has a chance to eagle at 18 and win the U.S. Open.
10:02PM: DJ crushes his drive on 18 ... and will also be looking to make eagle at the closing hole. Here's looking at you, Spieth.
10:00PM: DJ's back. Playing in the final group, Dustin Johnson makes birdie at 17 to get to 4 under and in a tie for the lead.
9:58PM: "Awesome shot." -Jordan Spieth, after knocking his 3-wood on the par-5 18th (yes, it's playing as a par 5 on Sunday) to about 15 feet for eagle.
9:57PM: A look at Oosty's scoredcard. Remember this is the guy who shot 77 on Thursday. SEVENTY SEVEN on Thursday, and is in the clubhouse with the lead at the 115th U.S. Open.
9:52PM: Everyone, remain calm. Jordan's got this.
9:51PM: King Louis? Louis Oosthuizen birdied 18 to get to 4 under and is your clubhouse leader. Meanwhile, Jordan Spieth 3-putted the 17th for double bogey and is at 4 under.
9:44PM: Leaderboard update:
9:41PM: We can't wait!
Spieth now has a 3-shot lead. Just like that. St. Andrews is about to get more interesting than an already is.— Doug Ferguson (@dougferguson405) June 22, 2015
9:38PM: #Manimal Jordan Spieth drains an unlikely birdie from up, over the ridge to get to 6 under. Meanwhile, Branden Grace makes double bogey and drops to 3 under.
9:33PM: Couldn't make it six. Louis Oosthuizen fails to birdie the 17th (would have been his sixth in a row) and remains at 3 under. #weaksauce
9:29PM: Advantage Spieth. Branden Grace knocks his tee shot at 16 out-of-bounds right and re-tees, hitting his third. Spieth with a decent lie just short of the green.
9:27PM: It makes it easier to add ...
"Birdie. Birdie. Birdie. Birdie. Birdie!" pic.twitter.com/TXLWxBIIKO— The European Tour (@EuropeanTour) June 22, 2015
9:25PM: Leaderboard update ... Spieth and Grace tied at 5 under with three to play. Also, that's a fifth consecutive birdie for Louis Oosthuizen to get him to 3 under.
9:22PM: Please, no. Just make it stop.
It definitely would have been interesting having the girls play here next week. I would have been interested to hear their opinions.— Erin Walker (@tourwifetravels) June 22, 2015
9:19PM: See? Chambers Bay isn't so hard.
Has Mike Davis gone soft? Round 3 yardage/scoring avg: 7,637/ 73.1 Round 4 yardage/scoring avg: 7,384/ 71.3 (in progress) #USOpen— Golf Central (@GolfCentral) June 22, 2015
9:16PM: What they said:
9:11PM: And then he birdies the 15th hole, too! Louis Oosthuizen made four birdies in a row and is now just three back.
9:08PM: ICYMI Louis Oosthuizen holed out for birdie on No. 14 to get to 1 under for the championship, four back.
9:05PM: Not their Day? Jason Day makes double bogey at 13 to fall back to even for the tournament and five back of Jordan Spieth and Branden Grace. Meanwhile, Dustin Johnson misses a 4-footer for par, drops to 3 under and trails by two.
8:57PM: And you made the right choice. (Not that you ever actually had one.)
Wish I was tweeting so excited for true detective in 5 mins but I'm not bc US open is on & marriage means compromise— Jessica Knoll (@JessMKnoll) June 22, 2015
8:52PM: Just so we're clear ... Billy Horschel's playing partner clears the air and confirms that he did not hit the ground on No. 6.
Played with Billy. No damage was done. Trolls lay off. You wouldn't be able to tell if did it anyway. Good round https://t.co/prHBOeLnwp— Ryan Palmer (@RyanPalmerPGA) June 22, 2015
8:49PM: Good news! DJ misses a short birdie putt at 12 to remain 4 under. How is that good? Well, So did Jordan Spieth one hole in front to remain 5 under.
8:47PM: I can think of a few guys ... who hope he's not too legit.
Branden Grace is 6 for 6 in closing career 54 hole leads. Dude's legit.— Kelly Tilghman (@KellyTilghmanGC) June 22, 2015
8:37PM: Lead change: Jordan Spieth and Branden Grace both birdie 12 to get to 5 under, while Dustin Johnson makes bogey at 11 to fall back to 4 under.
8:28PM: DJ can't get up-and-down on No. 10. His lead is down to one stroke over Grace and Spieth.
8:18PM: Well, well, well ... Adam Scott birdies 18 for a bogey-free 64, and he's posted 3 under par.
8:04PM: Nine down, nine to go.
7:58PM: Grace stuffs it on No. 9 for birdie, but DJ also makes a birdie on No. 8 to move two clear of Spieth and Grace.
7:50PM: Spieth birdies the par-5 8th to move one stroke behind DJ.
7:44PM: Great final round by Rory, but it doesn't look like it will be enough.
7:30PM: Snedeker knows how to rally.
Brandt Snedeker has 54-hole comebacks of 5, 6 & 7 shots in @PGATOUR career Began today 5 back. Now 3 off lead.— Justin Ray (@JustinRayGC) June 21, 2015
7:25PM: Sneeeeeeedeeeker closes out his front nine with four straight birdies, and he's only three back.
7:15PM: DJ just misses another chance for birdie on No. 5, and Day birdies to cut Johnson's lead to one stroke.
6:58PM: McIlroy now four back after a three-putt bogey on No. 15. Momentum has come to a screeching halt.
Two short missed opportunities for Rory McIlroy. Will be interesting to see if he thought he hit good putts.— Kelly Tilghman (@KellyTilghmanGC) June 21, 2015
6:55PM: Day with one of the worst putts you'll see on a major championship Sunday. Hits his 58-foot putt on No. 4 just 16 feet and doesn't get it over the ridge. Ends up saving bogey, but DJ makes a birdie to take the solo lead.
6:41PM: Rory misses golden opportunity by burning edge with short birdie putt on 14. He'll remember that if he ends up losing by one.
Rory McIlroy was tied for 25th entering today If he wins, it's the largest comeback (position-wise) in major championship history— Justin Ray (@JustinRayGC) June 21, 2015
6:36PM: Complain about Chambers Bay all you want, but this is the Sunday leaderboard it's given us. Could be worse.
6:26PM: And suddenly, McIlroy can't miss. Just two off the lead now after a dropping a 70-footer for birdie at No. 13. DJ and Day hear the roar and glance over at the leaderboard.
6:15PM: Rory, meanwhile, doing his best Johnny Miller impression. Things could get interesting if he posts a low number.
Rory McIlroy makes birdie at 12 to get to 5 under on the day. He’s only three shots off the lead. #USOpen— Jay Coffin (@JayCoffinGC) June 21, 2015
6:06PM: Spieth starts with bogey. Johnson and Day both with birdie putts inside 15 feet on No. 1. Advantage final pairing.
6:00PM: Buckle up. The final pairing of Dustin Johnson and fan-favorite Jason Day both rip it down the middle of the first fairway.
5:55PM: Just before the final group tees off, the president of the USGA tells Jason Day to come to him if he needs anything during his round. #Class
5:49PM: After nearly four hours of Sunday coverage, a couple of U.S. Open co-leaders have teed off. Jordan Spieth and Branden Grace playing the first hole.
5:42PM: In a shocking development, Caroline Wozniacki isn't rooting for Rory McIlroy today, despite the world No. 1's front-nine 32.
After everything @JDayGolf has been thru this week and the fight and grit he has shown, I'm rooting for him to win it all today!— Caroline Wozniacki (@CaroWozniacki) June 21, 2015
5:37PM: And ... just in case you thought Billy Ho had any positive thoughts on his week at Chambers Bay, spoiler alert, he doesn't.
Horschel also hammering fan experience at Chambers with hilly terrain and bad views/routing. Says fans "got robbed" this week.— Will Gray (@WillGrayGC) June 21, 2015
5:34PM: Holmes hits a chip that lands about a foot short of perfect on the first hole, then stands with his hand on his hip as the ball rolls right back to him.
5:30PM: The first under-par group is on the course, with J.B. Holmes (-1) and Shane Lowry (-1) having teed off.
5:24PM: Rory McIlroy is quietly sneaking up the leaderboard. He's 3 under for the day, through eight holes, and 1 over for the tournament.
5:20PM: In case you're wondering, what time a Monday playoff would take place. Here's your answer:
Just asked USGA folks about start time for a possible Monday playoff. Told it would be 3pm ET (Noon local). #USOpenChambersBay— Mike McAllister (@PGATOUR_mikemc) June 21, 2015
5:17PM: After shooting 67, Billy Horschel talked to the TV folks and said, "I've lost a little respect for the USGA this week."
5:15PM: How will this U.S. Open be remembered? More so for the champion or the conditions?
Ernie Els on Sunday’s greens at Chambers Bay: “They are putting much better now. They are basically not living anymore."— Rex Hoggard (@RexHoggardGC) June 21, 2015
5:08PM: Does Billy Horschel like the greens at Chambers Bay?
5PM: Keegan Bradley nearly aced the par-4 12th hole. Check it out:
4:55PM: Illinois' Brian Campbell is in the house at 5 over par, thanks to a final-round 68. He's currently the low amateur in the field.
4:48PM: Morgan Hoffmann tied the second lowest score of the week with a 4-under 66 on Sunday. He finished at 5 over.
4:42PM: We return to Chris Kirk, who had these parting shots:
The U.S. Open is a great tournament with incredible history. The @usga should be ashamed of what they did to it this week.— Chris Kirk (@Chris_Kirk_) June 21, 2015
4:30PM: Ben Martin was a cumulative 3 under for three rounds of the U.S. Open. Unfortunately, he shot 86 in Round 3 and finished at 13 over.
4:25PM: Speaking of Oakmont, Ernie Els won the U.S. Open there in 1994. He did this at Chambers Bay on Sunday:
4:18PM: After opening with a 69, Phil Mickelson shot 74-77-73 and finished at 13 over. Next year's U.S. Open, by the way, is at Oakmont. Mickelson missed the cut there when it last hosted an Open in 2007.
4:10PM: And now onto the action, where tempers are flaring early. Billy Horschel nearly tomahawked a green with his putter - and he's 5 under on the day. Chris Kirk made a 10 on the first hole en route to a 78, then had this to say:
Count Chris Kirk among the anti-Chambers crowd, esp. after a 10 on opening hole today. "I got here Tue PM, but I wish I got here Wed PM."— Will Gray (@WillGrayGC) June 21, 2015
4:07PM: And from 2013 U.S. Open champion Justin Rose, whose father passed away in 2002:
4:05PM: It's also Father's Day. And many in the field are paying tribute to their dads:
4:00PM: It's Sunday at the U.S. Open and we're still two hours away from the final group teeing off at Chambers Bay. Here is a look at pin positions:
