In only his fourteenth month as a professional golfer, Collin Morikawa was able to tackle one of golf's toughest feats, winning a major. In August 2020, Morikawa made his PGA Championship debut at TPC Harding Park in San Francisco. In his first two rounds, he shot a 69 both days which had him out of the top 10. However, Morikawa turned it on in the final two days of the tournament. In the third round, he shot a 65 and in the fourth round, he shot a 64. He finished 13 under par which was good enough to win his first-ever Major.
