Frustration is a common feeling among golfers when things don't go as expected on the course. Even top professionals aren't immune to taking out their anger on inanimate objects, as was the case with Wyndham Clark during the recently concluded U.S. Open.Images of the damage that Clark caused to the Oakmont locker room while venting his frustration by throwing blows were widely circulated on social media. A week later, the winner of the 2023 US Open addressed the issue after the first round of the Travelers Championship.As expected, Clark issued the apology that typically follows such behavior:"I've had a lot of highs and lows in my career, especially this year some lows. I made a mistake that I deeply regret," he said.However, Clark was equally quick to call for the issue to be put to rest:"I'm very sorry for what happened. But I'd also like to move on, not only for myself but for Oakmont, for the USGA, and kind of focus on the rest of this year and things that come up.""I still want to try to make the Ryder Cup team. I still am on the outside looking in for the FedExCup. So I'm starting to move on and focus on those things."Some players, most notably Graeme McDowell, came out in support of Clark, claiming to have been in the Denver native's shoes.However, this is the second time in less than a month that Clark has had to apologize for similar behavior. At the PGA Championship, he lost his temper again and threw his driver into a promotional fence on the 16th tee, endangering others who were in the path of the club.At the time, Clark didn't apologize through the press but rather through a statement on social media."As professionals, we are expected to remain professional even when frustrated...I promise to better the way I handle my frustrations on the course going forward," is part of what he posted then.Wyndham Clark missed the cut at the U.S. Open after shooting consecutive 74s in the first two rounds at Oakmont.A week later, he fared much better at the TPC River Highlands, posting seven birdies and one bogey in the opening round of the Travelers Championship. He currently sits tied for third at 6-under.More Golf: Rory McIlroy Dishes on PGA Tour Signature Events' Biggest Problem
