SOUTHAMPTON, N.Y. — Joaquin Niemann has violated golf’s new code of conduct policy, earning a two-stroke penalty at the U.S. Open for throwing a club. It resulted in him scoring an 11 on the par-4 sixth hole during the first round.The penalty occurred late Thursday night, as Niemann rushed to finish the remaining holes of his first round at the U.S. Open.The sixth hole at Shinnecock is 480 yards and borders the edge of the property and therefore features out-of-bounds territory down the right-hand side of the rough. Niemann started the hole by hitting two drives out of bounds, meaning he hit his fifth shot from the tee box, only to find a native area.According to Tristan Chang, a U.S. Open volunteer who witnessed the exchange, Niemann asked for a relief ruling related to fire ants near his ball. When that was denied, he kicked the flag that had been marking the ball, kicked the grass and chucked his club at least 50 yards.“It was a pretty impressive throw, actually,” Chang said.No video of the incident has been released, but Niemann did not deny any of it while speaking to reporters after his second round.“I had a bad lie on the third tee shot in between the fairways, and it was a pretty bad lie,” Niemann said. “I saw a lot of ants there, and I was just asking the referee if they were fire ants, and like, he say, no. To be honest, I was pretty — I wasn’t angry asking him. I was pretty normal, pretty chill, because I knew I needed to keep going and try to shoot the less possible.
