Hobart's Harry Bourchier has had a year to remember on the professional circuit, recognised by Tennis Australia as one of the country's most-improved players.
In an article on their website, the now-Victorian resident was listed as the third highest jump in rankings, rising 444 places from 736 to 292 at year's end.

The three-figure rankings difference was only bettered by Chris O'Connell, who jumped a mammoth 1065 players to sit 120th in the world and rising junior Rinky Hijikata who climbed 999.
Bourchier's first three months of his season saw the 23-year-old Southern product win 21 out of 26 matches including back-to-back Australian Pro Tour titles in Mornington.
An adventure on foreign soil proved fruitful, claiming Futures titles in Singapore and Hengyang before giving the Challenger circuit another crack successfully to enter the top 300 for the first time.
Other Australian males to improve their international rankings this season were: Alex De Minaur, Jordan Thompson, Alexei Popyrin, James Duckworth, Andrew Harris, Max Purcell, Akira Santillan, Aleksandar Vukic, Luke Saville, Dayne Kelly, Blake Mott, Matthew Romios and Brandon Walkin.
