Preparing For 2018

Career High
Cilic and Federer face off for the Australian Open title, a match the Swiss wins 6-2, 6-7, 6-3, 3-6, 6-1. The Croatian still climbs to a career-high ATP Ranking of No. 3 and sets his sights even higher. "My ultimate goal is to reach No. 1. That's what I'm working for." More...
A Long Time Coming
 "I was waiting many years for it to happen, so it’s definitely a happy moment," says Cilic in Rome after reaching his first Masters 1000 clay-court semi-final. He follows with a quarter-final run at Roland Garros. 
King Of Queen's
Cilic saves a championship point in the Queen's Club final against Djokovic, triumphing 5-7, 7-6(4), 6-3 after two hours and 57 minutes. He extends his streak of titles won to an 11th straight season. More...
Turning The Page
Marin turns the page on his second-round Wimbledon exit what he calls his "worst performance" in two years – with success at a pair of ATP World Tour Masters 1000 events. He reaches the quarter-finals in Toronto and the semi-finals in Cincinnati, both times falling to the eventual champions.
An Epic Comeback
Cilic claws back from two sets down to defeat #NextGenATP Australian Alex de Minaur in the US Open third round, completing his victory at 2:22am after converting his eighth match point. He reaches the quarter-finals before running out of steam against Nishikori. More..
Looking For Wins
Cilic struggles in Asia with a pair of opening losses, despite serving for the match in Tokyo and holding match points in Shanghai. Back in Europe, he finds his winning stride as he routs #NextGenATP star Denis Shapovalov in the Basel first round.
London Calling
