Even as a teenager, Siniaková showed amazing talent. By December 2012, she was ranked the No. 2 junior player in the world. In 2013, she and her fellow Czech partner, Barbora Krejčíková, won the girls' doubles titles at three of the four Grand Slam tournaments: the French Open, Wimbledon, and the US Open.

Early Professional Years

Siniaková started playing in professional tournaments in 2012. She quickly climbed the rankings. In 2014, she played in her first Grand Slam tournament, the 2014 Australian Open. That same year, she won her first doubles title on the main WTA Tour at the Tashkent Open. This success helped her break into the top 100 rankings in both singles and doubles.

By 2016, she was reaching the later rounds of big tournaments. She made it to the third round of Wimbledon in singles and reached her first two WTA singles finals. She was also becoming a top player in doubles, reaching the semifinals of the French Open with Krejčíková.

She won a second singles title later that year. In doubles, she reached her first Grand Slam final at the US Open with her partner Lucie Hradecká.

In 2018, Siniaková and Krejčíková had an incredible year. They won two Grand Slam doubles titles together at the French Open and Wimbledon. After these amazing wins and a strong performance at the US Open, Siniaková became the world No. 1 doubles player for the first time on October 22, 2018.
