September 27: Wins the Tour Championship, Spieth’s sixth PGA Tour victory of his career. At 22, Jordan Spieth is the youngest player to win five times in a PGA Tour season since 21-year-old Horton Smith in 1929.

He is also the youngest-ever winner of both the Tour Championship and the FedEx Cup(Ok, these are some of his less impressive achievements bearing in mind the Tour Championship is only 28 years old and the FedEx Cup eight years old). He is also the first player in history to win the Masters and the Tour Championship in the same year.

With his $1.4 million winning share, Spieth set a record for Tour earnings in a year with $12,030,465 – and the figure does not include his $10 million for winning the FedEx Cup.

With the victory, and with Jason Day finishing outside the top five, Spieth is once again No. 1 in the Official World Golf Ranking.
