2008: First ATP titles

Polášek reached his first ATP final at the 2008 Valencia Open with partner Travis Parrott, they fell to Máximo González and Juan Mónaco in two tight sets 5–7, 5–7. Later that year at the Swiss Open Gsaad he won his first title with partner Jaroslav Levinský in three sets.

2013: Retirement due to injury

In 2013 Polášek reached three ATP finals with partner Julian Knowle, winning the later two the Zagreb Indoors and the Grand Prix Hassan II.^[6]

In November 2013 Polášek retired from professional tennis at the age of 28 due to nerve issues and loose discs in his back.^[7]

2018: Return to tennis

Several years after retirement and allowing his body to heal through less strenuous activities such as coaching tennis and ski touring, Polášek hit with Mike Bryan and started playing some club matches again, and the pain of his previous injuries didn't seem to be reoccurring. He asked to take some time off from the coaching academy he taught at and started playing some futures and then challengers. By the end of September 2019 Polášek's doubles ranking had risen to within the top 200 for the first time in five years.^[7][8]

2019: First Masters 1000 title and Grand Slam semifinal

Polášek claimed his first ATP title in 6 years in Kizbühel, partnering with Philipp Oswald.^[9] At Wimbledon he reached his first Grand Slam semifinal partnering with Ivan Dodig in just their second tournament together.^[10] They then went on to capture their first Masters 1000 title as a team, and Polášek's first career masters title at the Western & Southern Open in Cincinnati defeating Juan Sebastian Cabal and Robert Farah in the final 4–6, 6–4, 10–6.^[11]

Polášek and Dodig then went on to take their second title as a team defeating defending champions Lukasz Kubot and Marcelo Melo to take the China Open title in Beijing.^[12]

2020: Second Grand Slam semifinal, World No. 7 in doubles

Dodig and Polášek began their 2020 season at the Adelaide International, where they reached the final, losing to Maximo Gonzalez and Fabrice Martin.^[13]

They then reached the semifinals of the 2020 Australian Open before being defeated by Max Purcell and Luke Saville.^[14] As a result he reached a new career-high doubles ranking of World No. 7 on 3 February 2020.

After this the ATP Tour was suspended due to the COVID-19 pandemic.^[15] On the tour's resumption in August at the Cincinnati Masters in New York and at the US Open they fell in the first round.^[16]

2021: Historic and first Grand Slam title at the Australian Open

Polášek and his partner Dodig reached the final of their first tournament in 2021 at the Antalya Open, where they lost to Nikola Mektic and Mate Pavic.^[17] After two weeks quarantine in Australia, they reached the semifinals of the Great Ocean Road Open, where they lost out to Jamie Murray and Bruno Soares.^[18] Continuing to partner with Dodig, Polášek won his first Grand Slam tournament at the Australian Open defeating Rajeev Ram and Joe Salisbury in the final.^[1] With the title he became the first Slovak male Grand Slam champion.^[4] As a result, he returned to the top 10 on 22 February 2021.
