"She has fairly good prospects for her to stay world number one; you can see a lot of paths for her to maintain her number one position", Tennis Australia (TA) analyst Stephanie Kovalchik said.
Riske broke down in tears at the end of her press conference when she spoke about the friendships she had built up over the years, especially the bond she forged with former British player and long-serving Davis Cup captain Paul Hutchins.
Having looked so assured in the first week - and a decent bet to end almost four decades of Australia being without a women's singles champion - she lacked the answers when required as Riske fought back to win 3-6, 6-2, 6-2.
If the score had reached 12-12, the pair would have played the first deciding-set tiebreaker since Wimbledon introduced new rules for this year's tournament. "I had to play aggressive".
"Today wasn't my day, but that's not going to define us as a team, it's not going to define me as a person", Barty said.
"It's so tough to beat Novak in the best of five and especially here on grass", admitted 28-year-old Goffin. I think it's something that is really important for someone like me who wasn't top 10, top 20, but Phil always remembered my name. It's like, Oh, now I can just play my game, hit shots, not have to worry about anything else. Riske has only shared the court with Williams once, as a doubles partner, knows her intensity will be off the charts and said she's ready "for a war".
Riske eventually did leave once she turned pro, moving to Hilton Head, S.C., after high school. "Like, OK, finally I can play tennis".
Defeat brought an end to 23-year-old Barty's 15-match winning run.
Barty began imperiously, booming four consecutive aces in her opening service game and marching through the first set.
Riske demonstrated the threat she posed when, with Barty an early break up, she responded in style to level.
Alison Riske, won by a final score of 3-6, 6-2 & 6-3.
Hercog then went a break up in the second and looked on course to progress to the fourth round with two match point opportunities.
It was all over when Barty speared a forehand wide of the court.
"She lost the first set and stuck with the plan". I'm really most proud about that.
Third seed Nadal, the 2008 and 2010 champion, swept to an easy 6-2, 6-2, 6-2 win over outclassed Joao Sousa of Portugal to book his place in a seventh quarter-final at the All England Club.
The 55th-ranked American scored her first career win over a world No. 1 to charge into her first Grand Slam quarterfinal in her 30th career major appearance.
"She's the greatest athlete I think that's ever been on the women's side".
"I feel like I've been there in every moment, looking to impose myself. I think it's been a really, really positive couple of months for us".
Riske had won the grass court title at 's-Hertogenbosch in the run-up to Wimbledon and her credentials on the surface eventually shone through as the match progressed.
"But in saying that, it's also only a tennis match".
"I chat to my niece and over and over she just tells me "you can go to infinity and beyond". The sun's still going to come up tomorrow.
They both believe the US Open is where Barty is best suited.
