Each player has had his or her own path to the elite eight of their respective draws, but they all have one thing in common: They're all still in the hunt to win their first Grand Slam title.

Read on for all the facts, stats and figures behind the four Americans to reach the singles quarterfinals at the Australian Open.

4 - Four Americans into the singles quarterfinals is the most of any nation. The Czech Republic is second with two, one man and one woman. 


2000 - It's the first time that three U.S. men are into the Australian Open singles quarterfinals in 23 years. (Andre Agassi, Pete Sampras, Chris Woodruff)


2005 - Three U.S. men, in fact, last reached the singles quarterfinals of any Grand Slam tournament at the 2005 US Open. (Agassi, James Blake, Robby Ginepri)


3 - Pegula is into her third straight Australian Open quarterfinal, having beaten Jaqueline Cristian, Aliaksandra Sasnovich, Marta Kostyuk, and 2021 Roland Garros winner Barbora Krejcikova to reach this stage. She's also the No. 3 seed, and is the highest seed remaining.

5 - It's Pegula's fifth career Grand Slam singles quarterfinal in all.


18 - Pegula has only lost 18 games in eight sets in her four victories. It's the fewest of any woman left in the field, ahead of Karolina Pliskova (19) and Aryna Sabalenka (21), who also haven't lost a set so far. 


8 - Pegula is on an eight-match winning streak. After losing her first singles match at the United Cup to Petra Kvitova, she won her next four matches to help the U.S. win the title, and has four wins in Melbourne.


5:16 - Pegula's 5 hours, 16 minutes on court in singles is the second-shortest cumulative time of the eight quarterfinalists. Only Pliskova (4 hours, 33 minutes) has been more efficient. 


21 - Pegula has broken serve 21 times so far, tying her for second-most in the women's event with her next opponent, two-time AO champion Victoria Azarenka.


1968 - Shelton, the 2022 NCAA singles champion as a sophomore at the University of Florida, is the first reigning NCAA singles champion to reach the quarterfinals of the following year's Australian Open since Arthur Ashe (UCLA) in 1966.


2022 - He's also the youngest American to reach a Grand Slam quarterfinal since Andy Roddick at the 2002 US Open.


141 - Shelton hit a 141 mph serve (228 kmh) earlier in the fortnight, which is the fastest serve of the men's singles event so far. 


1 - Shelton saved a match point in his first-round victory over China's Zhang Zhizhen. 


569 - This time last year, Shelton was not yet a full-time pro, and was ranked No. 569 in the ATP rankings. Arriving in Melbourne at No. 89, he'll shoot into the Top 50 as a result of this run, with the potential to go higher.


1998 - Korda is following in the footsteps of his father, Petr, with his Australian Open success. Petr Korda won the AO title in 1998, two years before Sebastian was born.


2018 - Korda is also the only man among the eight remaining to have won the junior Australian Open title. He reached world No. 1 after his boys' singles triumph in Melbourne five years ago. 


2 - Paul, unseeded, has beaten two seeds to reach this round. He defeated No. 30 seed Alejandro Davidovich Fokina of Spain in a five-set Round 2 match, and took out another Spaniard, No. 24 Roberto Bautista Agut, in four sets in Round 4. 


2009 - Shelton and Paul play each other in the quarterfinals, guaranteeing the U.S. will have its first Australian Open men's semifinalist since Roddick 14 years ago.
