Dustin Johnson arrived at Augusta National on quite a roll, having won his last three tournaments. He never even took a shot at the first major of the year. The world’s No. 1-ranked player was forced to withdraw from the Masters on Thursday because of a lower back injury suffered less than 24 hours earlier in a freak fall at the home he was renting for the week. “I want to play,” Johnson said. “I just can’t swing.” Johnson came into the week as the favorite to win the green jacket. But his quest to win his first Masters will have to wait another year.
