At the 2022 US Open, Barbora Krejčíková and Kateřina Siniaková achieved a very unique feat. Krejcikova and Siniakova have won all four majors, an Olympic gold medal, and the WTA finals. The US Open doubles title was the sixth doubles grand slam title for the pair.

Only Pam Shriver, Gina Fernandez, Serena Williams, and Venus Williams have completed the Golden Career Grand Slam. So Krejcikova and Siniakova are in company with the best doubles players of all time.

In addition to her doubles accomplishments, Krejčíková is an accomplished singles player. She has won one Grand Slam singles title at Roland Garros in 2021. She has also won three mixed doubles titles.
