Rickie Fowler and Xander Schauffele lead the U.S. Open 2023 standings at the end of the first day. Both players set a record for a round of this major with 62 strokes (-8). Other favorites and some surprises are also in the top positions.Fowler starred in a dream start, with 10 birdies (another record for the U.S. Open), including four of them in a row. The birdie he made after his ball fell into a barranca, almost under a bridge, on the eighth hole (par 5) was simply fantastic.DrunkByTheTurn@DrunkByTheTurn_Rickie Fowler made a birdie from here…221Rickie Fowler made a birdie from here… https://t.co/r4r5c4j8M5Just as good as Fowler's start was, Schauffele also began the 2023 U.S. Open in superb fashion. It was a bogey-free round with eight birdies, including back-to-back birdies twice during the round.Wyndham Clark is third with -6 after he started his round at full speed, scoring eagle on his first hole. He then made seven birdies and three bogeys to card a 64. It would have been good enough to lead the leaderboard in most U.S. Opens, but not in this one.Two heavyweights of the golf world, Dustin Johnson and Rory McIlroy, closed in T3 and T5, respectively. Johnson started his U.S. Open 2023 campaign with a solid performance, recording only one bogey to go with seven birdies, five of them on the back nine.In a day of records at the U.S. Open, McIlroy achieved a personal best for a front nine in majors (-5) and was bogey-free (six birdies), tied with Johnson and Clark. However, he failed to make par on the last hole of the round to drop to T5. Sharing that position with McIlroy is Brian Harman.Other favorites for leading the U.S. Open who started well included Bryson DeChambeau and Scottie Scheffler (T7, -3). Paul Barjon, ranked 570th in the world ranking and with only 34 tournaments played in the PGA Tour in his seven-year professional career, also finished the round in T7.There were some spectacular plays during the first round of the U.S. Open 2023. This included the two aces recorded on the 15th hole by Matthieu Pavon and Sam Burns. The spectacular birdie achieved by the amateur Michael Brennan on hole 3 was a treat for spectators as well.2023 U.S. Open full leaderboardBelow is the complete leaderboard for the 2023 U.S. Open:T1 Rickie Fowler -8T1 Xander Schauffele -8T3 Wyndham Clark -6T3 Dustin Johnson -6T5 Brian Harman -5T4 Rory McIlroy -5T7 Bryson DeChambeau -3T7 Scottie Scheffler -3T7 Si Woo Kim -3T7 Paul Barjon -3T7 Harris English -3T7 Sam Bennett -3T7 Mackenzie Hughes -3T7 Jacob Solomon -3T7 Dylan Wu -3T14 Max Homa -2T14 Ryan Fox -2T14 Alejandro Del Rey -2T14 Andrew Putnam -2T14 Joaquin Niemann -2T14 Alex Noren -2T14 Keith Mitchell -2T14 Tony Finau -2T14 Sebastián Muñoz -2T25 Ryan Gerard -1T25 Yuto Katsuragawa -1T25 Ryo Ishikawa -1T25 Gordon Sargent -1T25 Viktor Hovland -1T25 Jon Rahm -1T25 Eric Cole -1T25 Phil Mickelson -1T25 Cameron Smith -1T25 Sam Burns -1T25 Min Woo Lee -1T25 Justin Suh -1T25 David Puig -1T38 Jordan Smith ET38 Lucas Herbert ET38 Sergio Garcia ET38 Sepp Straka ET38 Gary Woodland ET38 Corey Conners ET38 Adam Hadwin ET38 Stewart Cink ET38 Mac Meissner ET38 Andy Svoboda ET38 Vincent Norrman ET38 Nick Hardy ET38 Thriston Lawrence ET38 Aldrich Potgieter ET38 Abraham Ancer ET38 Adrian Meronk ET38 Ben Carr ET38 Patrick Cover ET56 Omar Morales +1T56 Ryutaro Nagano +1T56 Adam Svensson +1T56 Pablo Larrazabal +1T56 Scott Stallings +1T56 Patrick Rodgers +1T56 Matthieu Pavon +1T56 Thomas Pieters +1T56 Sungjae Im +1T56 Collin Morikawa +1T56 Denny McCarthy +1T56 Barclay Brown +1T56 Charley Hoffman +1T56 Simon Forsström +1T56 Maxwell Moldovan +1T56 Romain Langasque +1T56 Austin Eckroat +1T56 Mito Pereira +1T56 Russell Henley +1T56 Matt Fitzpatrick +1T56 Chris Kirk +1T56 Patrick Cantlay +1T56 Brooks Koepka +1T56 Taylor Montgomery +1T56 Taylor Moore +1T56 Corey Pereira +1T56 J.J.
