Dan Evans suffered from his Wimbledon jinx as he was defeated 6-3 3-6 6-3 6-4 by debuting Sebastian Korda.
The 22nd seed and British No.1 was favourite to overcome the unseeded American on Centre Court.
It was a good chance to have a decent run [at Wimbledon]. It hurts to come up short, It feels like I'm running out time. It was a good opportunity at home. It's tough to go out like that. Dan Evans
But Korda, cheered on by his father Petr, a former tennis pro, will celebrate his 21st birthday by playing in the fourth round after Evans fell at the third hurdle for the third time after disappointments in 2016 and 2019.
Evans, 31, has been in rejuvenated form this year, scoring the third most wins of any player on the ATP Tour.
But luck – with net cords going against him and crucial moments – was against him and the big serve, powerful game and calm demeanour of his opponent proved too much. Even though the wannabe home hero was roared on by Derrick Evans – Mr Motivator – from the Royal Box
It was a clash of little and large with 5ft.9in Evans forcing 6f.5in Korda to bend early in the first set, but the American eased through to take it.
But Evans, with an effective backhand, battled back to level as the Centre Court stirred and offered him encouragement.
The third set was nip and tuck before Evans’ backhand went off the boil and Korda went back in front.
Evans took a 4-2 lead in the fourth, but he was broken and Korda completed the job.
Korda comes from a sporting family beyond his Australian Open winning dad, with mum Regina a top-100 player and sister Nelly the women’s Golf World No.1 claiming her first major at the US PGA Championship a few days earlier. And he hopes to give himself the perfect birthday present by beating Russian Karen Khachanov for a last-eight spot.
Legend John McEnroe, a multi Wimbledon champion, said: “He (Korda) got the game, the belief, the composure – he’s got it all, actually. Things can only get better.”
