Nick Kyrgios beats Yoshihito Nishioka 6-4, 6-3 to win the title in Washington DC for the 2nd time.
His 7th career singles title, first precisely since DC 3 years ago.
Kyrgios having the best year of his career: he would be #10 in the Race if the Wimbledon points counted.
The last time Kyrgios won an ATP final was at this same tournament in 2019 when he beat Daniil Medvedev.
Kyrgios fell to the ground after wrapping up the final against Nishioka and revealed how much the victory meant to him post-game.
"Just very emotional for me. To see where I was at last year to now, it’s just an incredible transformation," Kyrgios said.
"I’ve been in some really dark places and just to be able to turn it around. I think there are so many people that have helped me get there, but myself I’ve shown some serious strength to just continue and persevere through those times."
Kyrgios' title celebrations will be cut short though as he backs up in the men's doubles final with Jack Sock which will be played straight after his singles final.
The Australian is looking to secure successive doubles titles after winning the Atlanta Open with Thanasi Kokkinakis last week.
