Jason Day

Australian professional golfer (born 1987)

Jason Anthony Day is an Australian professional golfer. Day had early success as a professional, earning PGA Tour membership in his teens and winning an event in his third season, the HP Byron Nelson Championship. In 2015, Day recorded his breakout season, winning five events including the PGA Championship, a major championship, and became the 19th man to ascend to the world No.1 ranking. Day maintained exemplary play through 2016, winning three tournaments including The Players Championship, and nearly defending his PGA Championship, finishing in solo second place by one stroke, and would spend the last 40-consecutive weeks of the season ranked No. 1. Day would hold the No. 1 spot for 47-consecutive weeks, the 13th longest streak all-time, and for a career total of 51 weeks, 10th most all-time. Since that season, however, Day's play has been much more erratic and he ultimately fell outside of the top 100 in the world. In 2023, however, he recorded a comeback year, winning the AT&T Byron Nelson, the site of his first win, finished T2 at the British Open, and returning to the world's top-20.
