On 7 April, McIlroy shot a bogey-free 7-under-par 65 in the first round of the Masters Tournament in Augusta, Georgia to take the lead after the first day of the four-day competition. At the time, he was the youngest player to lead the Masters Tournament at the close of the first day. On Friday, he shot 69 to lead by two strokes over Jason Day with a 10-under-par score. On Saturday, he shot 70 to finish at 12-under-par, four strokes ahead of four other challengers. However, on the fourth and final day, he shot the worst round in history by any professional golfer leading after the third round of the Masters Tournament. McIlroy scored one-over-par 37 on the first nine, and still had the lead, but shot a round of 80, finishing T15 at 4-under for the tournament.
