Golfer Joaquin Niemann was penalized during the US Open. The penalty was for throwing his club, which resulted in two additional shots being added to his score. This incident occurred late in the first round of the tournament.

The USGA handed down the penalty, turning one of Niemann's scores into a higher number. Specifically, a 9 became an 11 due to the penalty. This action is part of a broader trend of golf authorities cracking down on poor behavior by players.
