John Peers has ended the season as the top-ranked Australian in men's doubles for the eighth time in his career - and impressively, for the seventh season in a row.
The resurgent Peers finishes 2021 at world No.13, having captured two titles from four finals appearances. The 33-year-old also contested a further four semifinals, including at the US Open in his best Grand Slam result in more than two years.
Peers has been rewarded with the fourth top-20 finish of his career and his highest year-end ranking since concluding the 2017 season at world No.4.
