Washington, USA: Australia's Nick Kyrgios overcame a mid-match meltdown and his rival's shoe repair delays Saturday to defeat Greek top seed Stefanos Tsitsipas and reach the ATP Washington Open final.
The 52nd-ranked Aussie hammered 19 aces, saved a match point and often played to the crowd in a dramatic and emotional 6-4, 3-6, 7-6 (9/7) victory over Tsitsipas, whose broken shoes caused two third-set delays.
Tsitsipas, who becomes world number five on Monday, fell behind a set and a break, took advantage of Kyrgios losing control with racquet slams and call complaints to force a third set, only to fall in the tie-breaker.
"It was spiraling out of control at one point," Kyrgios said. "I've been in that spot before and it has gotten worse.
"I'm pretty proud at how I was able to drag it back from a dark place. I'm pretty proud of how I battled back and dug deep."
Kyrgios will play for the $365,390 (328,851 euro) top prize against 10th-ranked Russian Daniil Medvedev, who eliminated German lucky loser Peter Gojowczyk 6-2, 6-2.
The 24-year-old Aussie beat Medvedev this year in Rome in their only prior meeting.
Kyrgios, who improved to 4-1 against top-10 rivals this year, seeks a sixth career ATP title and his first since Acapulco in March.
"It's probably one of the best tournament weeks of my life," Kyrgios said.
Medvedev, 23, seeks his fifth ATP title after taking his most recent crown at Sofia in February.
Italy's 62nd-ranked Camila Giorgi, a 2018 Wimbledon quarter-finalist seeking her third WTA title, and 79th-ranked American Jessica Pegula advanced to the women's final at the US Open tuneup tournament.
Kyrgios excited the crowd throughout with such flamboyant moves as underhand serves, between the legs shots and leaping drop shots. Other times he would just swat away.
"He was on fire in some moments," Tsitsipas said. "It felt like sometimes he didn't care at all. It's probably his plan to put you out of focus."
Kyrgios admitted, "I've always been able to play high level tennis. I just need to be more consistent. I have to be mentally tougher."
It was the Greek star's first match against Kyrgios, who is of Greek and Malaysian heritage. Each man won 91 points, hit 58 of 91 first serves, won 48 of 58 first-serve points and 16-of-33 second serve points.
"I'm an anti-stat guy," Kyrgios said. "I don't look at any of that stuff."
Kyrgios broke in the third game and held from there to win the first set in 31 minutes, dropping only three points on his serve.
"His serve was just unreal first set. I couldn't do anything with it," said Tsitsipas. "I haven't seen anything like it."
Kyrgios broke again to open the second set but after a review call went against him double-faulted away a break, slamming his racquet and towels to the court in frustration.
