Another of our favourite moments from the #DavisCupYear is Lleyton Hewitt's short-lived retirement! Lleyton retired after the Australian Open in January, but returned to the court in March when Nick Kyrgios got injured before the #DavisCup first round!
Having dropped outside the world's Top 1000 in January, Juan Martín del Potro has ended the year back inside the Top 40, won an ATP title, picked up an Olympic silver medal... and is now a Davis Cup champion. What a year!
More good news for Argentinian fans... Argentina has risen to the top of the ITF Davis Cup Nation Ranking for the first time, becoming the eighth nation to reach top spot since the rankings were introduced in 2001.
