But at 5-over 149, he'll have the weekend off, too.
Day and McIlroy, just to name a few, might not make it that far.
"I just played bad golf, man", Day said with a chuckle.
Getting a weekend off are the world's top three ranked players; number one Dustin Johnson, number two Rory McIlroy and number three Jason Day, who all missed the cut leaving a decidedly unglamorous leaderboard.
"You can not play this golf course if you're not in position off the tee, and I wasn't in position", McIlroy said.
While McIlroy and Day will return to competition next week at Travelers, Johnson, who welcomed a second son to the family earlier this week, will be taking a month off. After another week, it's the WGC-Bridgestone and PGA Championship.
Beginning one off the pace, Casey birdied the 11th to move alongside Fowler but slipped down the leaderboard by following a blemish at the next with a triple-bogey at 14 and bogey at the 15th.
"I know it's cliche, but the last thing you need to be doing is thinking ahead, especially on this golf course". "And unfortunately, this didn't pan out".
A 94-year-old spectator has died at the U.S. Open. He said that his 16 years of experience is what allowed him to keep the wheels from falling off on the par-5 14th hole. He smoothed that out on Friday, and had better results.
Asked if he would have been able to recover from such a mistake earlier in his career, Casey added: "In my good seasons, yes, but there have been times when I struggled, so probably not! And I was just trying to show that". He has birdied three of his last four holes. McIlroy was 4 shots off the cut line and Day a whopping 9 shots removed.
"It was a good display, all my own fault, but a good display of what can happen if you get out of position on this golf course".
"[Thursday], coming off an injury, I was a little anxious going out there, " McIlroy said. I got out of position, but it's the attitude, it's the grit that matters at the end of the week. "I think it's going to produce a really great champion". Everything was in good shape. I guess I've just kind of always been that way.
The player who turned the US Open into a soap opera of sorts the previous two years won't be around for the weekend this time.
Despite a flurry of late birdies it was not enough to turnaround an erratic round littered with errors and missed opportunities. The 2011 U.S. Open champion joked that this championship has become his "annual missed cut". He never expected to be making those plans on a Friday. This week, he didn't have it.
"But for me, it felt like it played tougher today. But at least I'll get to sit in air con [conditioning] and watch the guys tear it up on the weekend".
Jason Day, of Australia, hits from a bunker on the eighth hole during the first round of the U.S. Open golf tournament Thursday, June 15, 2017, at Erin Hills in Erin, Wis.
That gave Oosthuizen a record total of 132 for the middle two rounds and after bogeys at the second, third and fourth in the final round looked to have ended his chances, he carded six birdies in the last seven holes for a record-equalling back nine of 29 and outright record of 199 for the last 54 holes.
