Nick Kyrgios overcame a bothersome back and used two of his 18 aces to close things out with a two-tiebreaker victory over No3 seed Daniil Medvedev to win the Citi Open final.
Kyrgios won his second title of the year and moved his ranking back into the top 30 with a 7-6 (6), 7-6 (4) win.
“Yeah, it’s amazing. Honestly, you know where I was six months ago. Some of the things I was doing. I was just putting myself in a really tough situation and to respond like this, having incredible support, it’s amazing,” the Australian said of his victory.
“I’ve had people behind me, backing me, and they never lost faith in me even though I lost it in myself. This week means a lot.
“Obviously, it’s great to get the win but, you know, I’ve proved to myself and to a lot of people that are backing me that I still have it and can still produce at the highest level.”
Nick Kyrgios saved a match point as he overcame top seed Stefanos Tsitsipas to reach the final of the Citi Open in Washington.
The Australian notched up his fourth win against a top-10 player this year as he downed his Greek opponent 6-4, 3-6, 7-6 (7) in two hours and eight minutes.
Kyrgios got off to a flying start, breaking Tsitsipas in his second service game before clinching the opening set.
But the world number six remained undeterred and fought back to level up the match at one set all.
A closely-fought decider ended in a tiebreak, with Krygios firing a service winner to save a match point against him at 6-5 down before eventually triumphing on a second match point of his own.
The Australian will now face Daniil Medvedev, after the Russian ousted lucky loser Peter Gojowczyk.
Medvedev had a more straightforward semi-final clash, needing just 56 minutes to win 6-2, 6-2.
The 23-year-old converted all five of his break-point opportunities and won 78 per cent of his first-serve points during the match.
Meanwhile, Dominic Thiem triumphed on his home soil as he won the Austria Open title in Kitzbuhel.
The world number four saved all six break points he faced to defeat Albert Ramos-Vinolas 7-6 (0), 6-1.
Andy Murray admits he is in a “much better place” as he continued his comeback from injury on Wednesday, pairing up with brother Jamie to progress to the second round at the Citi Open in Washington.
The brothers were playing together for the first time in almost three years and beat French pair Nicolas Mahut and Edouard Roger-Vasselin in the first round of the men’s doubles, clinching a 6-4, 7-6(7), 10-5 victory.
The Scots will face either Kevin Krawietz and Andreas Mies or Raven Klaasen and Michael Venus in the second round.
Murray’s fourth men’s doubles appearance of the 2019 season is the latest step in his recovery from hip surgery and he said: “I’m in a much better place, now than I was last year.
“Even though I was winning singles matches, physically I just feel so much better. I have no pain. It’s not restricting me in any of the shots that I’m hitting. I’m still maybe a little bit slower.
“I’m hoping that’s something that will come back with time, but… I didn’t know how much more I was going to be playing after here (at the Citi Open) last year. And yeah, to come back and be competing and be pain free is brilliant.”
