U.S. Open 2021: How the 36-hole cut is determined at Torrey Pines

June 18, 2021

The tournament within a tournament at the U.S. Open comes into full focus on Friday at Torrey Pines. Of course, players will be jockeying for position atop the leader board in hopes of eventually winning the championship come Sunday. But many others will be trying to just make sure they’re here for the weekend by making the tournament’s 36-hole cut.

Unlike the PGA Championship and the Open Championship, which allows the low 70 players and ties to play all four rounds, the USGA has a slightly higher bar for its “cut rule,” taking only the low 60 and ties. And there is no “10-stroke rule” in effect to help determine the U.S. Open cut; the USGA did away with it in 2011.

With nearly two dozen players posting under-par scores in the first round, the projected cutline from datagolf.com early at the start of the second round on Friday was 37.0 percent probability of three-over-par 145 and a 46.1 percent probability of four-over 146.

If you think just making the cut doesn’t mean much in determining the ultimate winner, consider what happened three years ago at Shinnecock Hills. Tony Finau and Daniel Berger had made the 36-hole cut with one stroke to spare, but were 11 strokes off the lead when they teed off on Saturday morning in the third round. They each posted four-under 66s, and when the winds picked up in the afternoon—along with the scores—Finau and Berger found themselves tied for the lead after 54 holes. Finau would eventually finish fifth and Berger would come in tied for sixth, each securing spots into the 2019 championship with their weekend play. So yeah, even just making the cut is a big deal. (Oh, and they’re playing for $12.5 million in prize money, so getting to the weekend, even on the number, can be financially very lucrative, too.)

One of the bigger questions at the U.S. Open is also whether any of the nine amateurs competing will make the cut. An amateur has made the cut every year since 2007, and four of this year’s participants were among the top 80 after Day 1 at Torrey Pines, suggesting that somebody will earn the low-amateur medal come Sunday.

Here's what the cutline has been for the last 10 U.S. Opens:

2020: 146 (+6), Winged Foot
2019:
144 (+2), Pebble Beach
2018: 148 (+8), Shinnecock Hills
2017: 145 (+1), Erin Hills
2016: 146 (+6), Oakmont
2015: 145 (+5), Chambers Bay
2014: 145 (+5), Pinehurst No. 2
2013: 148 (+8), Merion
2012: 148 (+8), Olympic Club
2011: 146 (+4), Congressional

And at the other U.S. Open at Torrey Pines:
2008: 149 (+7)
