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.”
