You can't try to be too aggressive; today for me was a prime example."I was a little too aggressive to the pin on 11, a little too aggressive to the pin on 12 - all of a sudden, just two bogeys in a row out of nowhere.""I think you still have to play smart, try to keep the ball under the hole, hit it into the middles of the greens and take your chances when they present themselves."Wyndham Clark has been the standout performer so far in the US Open, shooting an incredible 64 in round one.The American has been in control, with either a crumble in the third and fourth rounds or one of the chasing pack breaking through to prevent him from winning a second US Open.A year ago, the 32-year-old ruined a locker in the historic Oakmont clubhouse after missing the cut in the defence of his title.Fast-forward 12 months, and the American could breathe easier, being comfortably ahead after a one-under 69 kept the lead at four after round two.He said: "I've gotten a lot of grief since last year, rightfully so. The thing that's unfortunate is that's not who I am, what happened last year."I'm hoping I can win back the fans that I had or some new fans because it was a terrible incident."I really feel like I can show people that I'm fun and outgoing, I'm fierce, competitive, love the game, respect the game, and I just had a bad moment."Our Standards: The GB News Editorial Charter
