Dustin Johnson struggles during second round at U.S. Open

Dustin Johnson started strong at the U.S. Open, finishing his first round at 4 under par. However, his second round at Shinnecock quickly deteriorated, highlighted by a double bogey at the 11th and a quadruple-bogey at the 15th. As the round progressed, Johnson went from being tied for second to potentially facing the cut. He needs to finish strongly to qualify for the weekend rounds after posting a birdie at the 16th.
