Andy Murray had a sensational 2012 season where he was a finalist at Wimbledon, Olympic singles champion and finalist in the Olympic doubles with Laura Robson in London.
This was before his triumph at the Flushing Meadows, becoming the first British male to win a Grand Slam since Fred Perry in 1936.
He was a huge threat to Novak Djokovic throughout the whole year and 2012 was acclaimed as his breakthrough season.
This year, Murray has had a decent season, but he has not challenged for the world number one ranking.
Although he started well by reaching the final of the Australian Open, a back injury forced him to withdraw from the French Open.
He returned at the Aegon Championships in preparation for Wimbledon, which he won.
Going in to Wimbledon, Murray hadn't lost a match on grass since the previous year's final, and was on a winning streak of 11 matches on grass.
After some great displays, he won Wimbledon, becoming the first British male to win at SW19 since Perry.
However, he failed to impress thereafter and a disappointing season culminated with Murray withdrawing from the ATP World Tour Finals in order to undergo surgery on his back.
Throughout 2013, Murray was unable to compete with Rafael Nadal, who was not present at the Australian Open and was knocked out early in Wimbledon.
Such was the disappointment of Murray's post-Wimbledon season that he finished fourth in the world rankings, behind Djokovic, Nadal and David Ferrer.
In fact, Murray finished with less than half of Nadal's ranking points. Clearly he has a lot of ground to make up next season.
Nonetheless, Murray showed glimpses of his exceptional talent, and with age on his side, the sky is the limit for the 26-year-old. If anyone can challenge the supremacy of Nadal and Djokovic, it is Murray.
