Former champion Wyndham Clark has apologised for an infamous locker-room meltdown after seizing command of the 126th US Open in New York.
Clark had a four-shot lead slashed in half after returning to Shinnecock Hills early on Friday morning to conclude his weather-delayed first round but he then wrestled back control.
The 2023 winner followed up his opening 64 with a second-round 69 to move to seven under and open a four-stroke lead over fellow American Xander Schauffele (71-66) and England's Matt Fitzpatrick (67-70).
Clark was last year embroiled in controversy when caught destroying multiple lockers after missing the halfway cut at brutal Oakmont Country Club.
But the 32-year-old has been a picture of calm and control in separating himself from the field so far this week.
