There was brilliance. There always is. There were injuries, so more of the same there, too. No titles, and no grand run into the second week of a major, but two finals including a first at Masters 1000 level in Cincinnati, wins over Rafael Nadal and Novak Djokovic, and a role in one of the ATP’s matches of the year - against Roger Federer in Miami.
If his friend and Davis Cup captain, Lleyton Hewitt, is fond of saying that Davis Cup is responsible for the highest highs and the lowest lows of a player’s career, then Kyrgios experienced some of that, as well. He carried a 3-0 singles record from Australia’s first two ties into the semi-final in Belgium, won on day one, lost on day three, and left no-one in any doubt how much all of it meant.
“2017 has been a year of ups and downs for me and one I will look to improve on in 2018, but the real highlight in 2017 for me was having the opportunity to pull on the green and gold in Davis Cup alongside an unbelievable captain in Lleyton Hewitt and a great group of guys as team mates,’’ Kyrgios says. "Davis Cup was my only goal this year and I poured my heart in to it, and I will do so again in 2018 in the hope we can go on and win it for Australia."
