When Ash Barty won the French Open in 2019 for her first grand slam triumph, she took down four Americans on her way to the title.
The Australian star beat Jessica Pegula in the first round, Danielle Collins in the second, Madison Keys in the quarter-finals and Amanda Anisimova in the semis.
'IT'S TERRIBLE': Ash Barty's coach drops post-match bombshell
On her way to the Australian Open title on Saturday night, Barty also had to go through four Americans.
And once again they were Pegula, Collins, Keys and Anisimova.
This time she beat Anisimova in the fourth round, Pegula in the quarters, Keys in the semis and Collins in the final.
She actually beat five Americans at Roland Garros in 2019, adding Sofia Kenin to her list of scalps in the fourth round.
But the fact that she beat the same four players on her way to both titles is downright unthinkable.
"Crazy that Barty beat the same four American players when she won the French Open and Australian Open," American journalist Christopher Clarey tweeted on Saturday night.

US Open gonna make sure all those 4 players are in the opposite half of Barty’s draw! Haha

Let alone they’re all from the same country, odds must be minuscule

However the spooky anomalies don't stop there.
Barty became the first Australian to win their home grand slam in 44 years, beating Collins 6-3 7-6.
The last local player to win the Australian Open was Chris O'Neil in 1978, when she beat Betsy Nagelsen in the final by the exact same scoreline 6-3 7-6.
And just to top things off, Nagelsen is the former coach of Collins.
Chris O'Neill, the last Aussie woman to win the title, had won the final with the same score as Barty today: 6-3, 7-6.

Um, guys? The last time an Aussie woman won the Australian Open (by Chris O'Neill), the score was 6-3, 7-6, against an American...
Just like Ash Barty achieved tonight.

Amazing win by Ash Barty 44 years after Australia's last women's champion Chris O'Neil with the exact same scoreline 6-3 7-6 also defeating an American #ashbarty🇦🇺 #tennisaustralia #australianopen2022 #wta #itf https://t.co/u7wfWqiwxb

Quirky that the last time before Ash Barty's win that an Aussie won an Australian Open singles title was at the expense of an American in the final by the same 63 76 scoreline. That American player from 1978, Betsy Nagelsen, ironically, at one time coached Danielle Collins!

World delights in Ash Barty's Australian Open triumph
The tennis and wider sporting worlds are delighting in Barty's amazing triumph after the World No.1's historic victory.
Men's tennis great Rod Laver posted a photo on Twitter with Barty, Evonne Goolagong Cawley, O'Neil and Judy Dalton and hailed the 25-year-old's "special" achievement.
"A Grand Slam champion on three different surfaces, you are the complete player @AshBarty and I am so happy for you tonight," he tweeted.
"There's nothing like winning at home, congratulations #AO2022 champion, it is wonderful to be here for this moment and to celebrate with Australia."
— Rod Laver (@rodlaver) January 29, 2022
Two-time Australian Open champion Victoria Azarenka hailed the brilliant 25-year-old.
"There is just no better tennis player at the moment than @ashbarty," Azarenka tweeted.
"Most complete and focused! The way she is able to put pieces together and add a bit more to her game is absolutely admirable!
"What an example!"
Australian tennis legend Sam Stosur, who marked her 20th and final singles appearances at Melbourne Park, delighted in her compatriot's success.
"I am speechless. You can't be speechless on radio but I am," Stosur said on SEN radio.
Many delighted in seeing proud Ngarigo woman Barty enjoying the moment alongside her idol Goolagong Cawley and athletics great Cathy Freeman - fellow Indigenous women.
"Ash. Evonne. Cathy. A triumvirate of brilliant women," Australian netball great Liz Ellis tweeted.
