For the second consecutive day, a player posted a front-nine 29 on the North Course of The Los Angeles Country Club, matching the U.S. Open record. Austin Eckroat, of Edmond, Okla., a former standout at Oklahoma State and a member of the 2021 USA Walker Cup Team, flirted with a 28, just missing an 11-foot birdie on the par-3 ninth hole. He then bogeyed the 12th hole to stall his pursuit to not only skyrocket up the leader board but also possibly establish a final-round scoring mark. It was 50 years ago  that Johnny Miller won at Oakmont Country Club with that famous closing 63. In Saturday’s third round, Tom Kim shot the fifth 29 in championship history, following Neal Lancaster, who did it twice (1995-96), Vijay Singh (2003) and Louis Oosthuizen (2015). In 2017, Eckroat was the stroke-play medalist in the U.S. Junior Amateur, losing in the quarterfinals to future OSU teammate Matthew Wolff at Flint Hills National in suburban Wichita, Kan.
