She defeated Petra Martić and Yulia Putintseva in straight sets to advance to the third round. In the third round she lost a tight 3-hour/3 set match to CoCo Vandeweghe.

Radwańska was forced out of the Pan Pacific Open tournament in Tokyo due to a bout of flu. At the Wuhan Open, she scored her fifth career win over Wimbledon semifinalist Magdaléna Rybáriková in the first round. She defeated Julia Görges in the second round, claiming her 500th main draw victory on the WTA. Radwańska avenged her straight-set loss to Görges earlier this year, at the Western & Southern Open in Cincinnati, and increased her head-to-head record against the German to four wins and two losses. A quarterfinalist in Wuhan last year, Radwańska lost to the eventual finalist, Ashleigh Barty in the third round, after the Australian dispatched No. 5 seed Johanna Konta.[83] Radwańska began her title defense at the China Open with two straight-sets victories over Carina Witthöft and Zhang Shuai before falling to Daria Kasatkina in a third-round three set meeting. Radwańska ended her season ranked 28th, her worst since 2005, following a second round defeat in Hong Kong to Samantha Stosur.

At the end of the season Radwańska won the 2017 Shot of the Year for the fifth time in a row. She turned defense to offense in a stunning way to thwart a would-be winner from Julia Görges during their match at Wuhan Open.[84]

Radwańska in 2018

Radwańska began the year at the Auckland Open where as the fourth seed, she defeated Beatriz Haddad Maia and Taylor Townsend but lost to qualifier Sachia Vickery in the quarterfinal. She then competed at the Sydney International, overpowering the defending champion Johanna Konta and Catherine Bellis to advance to the quarterfinal, where she lost to Camila Giorgi. This loss caused Radwańska to fall out of the top 30 for the first time since 2007 since she was unable to defend her finalist points at the tournament. Radwańska was seeded 26th at the Australian Open. She reached the third round, after defeating Kristýna Plíšková and Lesia Tsurenko, but lost to Hsieh Su-wei, who beat Garbiñe Muguruza in the second round. Radwańska made it three three-set victories in a row over Mona Barthel to make a winning start to her Qatar Open campaign. She ultimately needed 10 match points, but avoided the tiebreak and finally closed out the match after two hours and 26 minutes. "I’d rather not talk about those ten match points!" Radwańska joked. "The important thing is I won the tenth one".[85] In the second round, Radwańska lost to the eventual champion Petra Kvitová in three sets.[86]

At Dubai, Radwańska lost to eventual finalist Daria Kasatkina in the opening round.[87] Her next tournament was the Indian Wells Open where she received a bye into the second round. There, she lost to the eventual champion Naomi Osaka, who defeated unseeded Maria Sharapova in her opening match. At the Miami Open, Radwańska made a promising start, defeating world No. 1, Simona Halep, in three sets. This victory marked Radwańska's second career win over a world No. 1, and the first since 2012. She extended her great record in Miami, too; reaching the round of 16 or better in ten of her 12 appearances.[88] Radwańska ended her run in Miami with a loss to Victoria Azarenka in the fourth round. After Miami, she was promoted from 32nd to 30th in the WTA ranking. Radwańska opened her clay-court season in Istanbul where she retired in the first-round match to Donna Vekić. It was later revealed that Radwańska hurt her back the day before during a training session. Subsequently, she withdrew from the Mutua Madrid Open and French Open due to a back injury.[89] Radwańska made a winning return from injury against Tímea Babos in the first round of the Nature Valley International. Despite missing a Grand Slam event for the first time in over a decade, dating back to the 2006 French Open, the former world No. 2 looked as though she'd never left over the course of 66 minutes on the Eastbourne lawns. Radwańska, unseeded in Eastbourne, defeated No. 15 seed Daria Gavrilova to face Petra Kvitová in the third round. Since Petra Kvitová withdrew with a hamstring injury Radwańska automatically advanced to the quarterfinal where she defeated Jeļena Ostapenko to reach the semifinal. In the semifinal, she lost to Aryna Sabalenka in three sets.

At Wimbledon, she defeated Elena-Gabriela Ruse in a close three-set match, saving six match points and reeling off the last three games in a row to book her place in the second round.[90] In the 2nd round she played Lucie Šafářová, to whom she lost in straight sets. For the first time in her career Radwańska lost to Karolína Plíšková in the first round of the 2018 Western & Southern Open, bringing their head-to-head to 7–1 against the Czech. Next she played at the Connecticut Open where she lost to Petra Kvitová in the opening round. For the first time in over a decade, Radwańska came into a Grand Slam main draw outside the top 32 seeds. Unseeded at the US Open, she lost to Tatjana Maria, in the first round. Radwańska progressed to the second round of the Korea Open thanks to a two set victory over Bethanie Mattek-Sands.[91] In a clash of two former winners of the Korea Open, 2013 champion Radwańska lost to the 2015 champion Irina-Camelia Begu in the second round.[92]

Due to her ongoing struggles with injuries Radwańska withdrew from the China Open tournament, thus ending the season early with a 14–14 singles record. By the end of the season, Radwańska fell to the 78th position in the ranking – the lowest since 2006, when she made her debut in the WTA series. On 14 November 2018, Radwańska announced her retirement from professional tennis. "Taking into consideration my health and the heavy burdens of professional tennis, I have to concede that I’m not able to push my body to the limits required," she wrote on her Facebook account.[93]

In over a decade of meetings, Radwańska and Caroline Wozniacki had a rivalry that ended 11–6 in Wozniacki's favour. Radwańska first scored a win against Wozniacki in July 2007 at the Nordic Light Open in Stockholm. She also defeated Wozniacki at the Sydney International, Pan Pacific Open in Tokyo, and tournaments in Doha, Wuhan and Beijing.[97] In August 2017 they faced each other for the last time at the Rogers Cup in Toronto, where Wozniacki beat Radwańska to advance to the quarter-finals.

Radwańska and Zvonareva after the 2011 Pan Pacific Open final

Radwańska had a rivalry with Russian player Vera Zvonareva,[98][99] which began in 2007. It ended 4–2 in Radwańska's favour.[100]

Throughout their meetings, Radwańska proved able to match Zvonareva's pace and movements around the court.[101] Zvonareva was considered the more powerful of the two, while Radwańska was noted as more focused at times,[29][101] utilizing what Sports Illustrated's Courtney Nguyen dubbed "selective aggression" during the pair's 2011 matches.[102]

Their first match occurred during the 2007 Kremlin Cup, with Zvonareva winning in straight sets. The two did not play again until the 2011 season, when Radwańska won four of their five matches, including the finals of the Mercury Insurance Open and the Pan Pacific Open. Their final meeting of 2011 was an acclaimed match at the WTA Championships.[103] Trailing 3–5 in the third set, Radwańska saved three match points and went on to win in three sets. The victory marked her fourth straight win against Zvonareva, whom she described as "very consistent and always tough to beat."[104]

Radwańska and Li Na[105] first played in 2009. Li led the series 6–5. Radwańska won the three of their four matches on grass and their only meeting on clay. Li led the rivalry 5–1 on hard courts.[106] Their matches included a victory each at Wimbledon: Radwańska winning in 2009 and Li in 2010. In 2012, Radwańska and Li met four times, with Li taking three victories. Li lost their meeting in the Stuttgart quarter-final in three sets, but dominated in Montréal, Cincinnati and Beijing. In 2013, both were undefeated that year when they met each other in the semi-finals at Sydney. Radwańska beat Li and eventually won the tournament. At the 2013 Australian Open, Li became the first player to defeat Radwańska that season, with a victory in the quarter-finals. Their last meeting came at Wimbledon that year, in the quarter-finals, with Radwańska winning in three sets.[107]

Radwańska and Ana Ivanovic had their first professional meeting in 2006.[108] With Ana Ivanović having retired, Radwańska ended the series 7–3 ahead. The majority of their matches were played on hard courts. Radwańska lead their match-ups on clay.[109]

Radwańska versus Angelique Kerber has been described as one of the closest rivalries in women's tennis.[110] The rivalry stretches back to their first meeting in 2008 Qatar Telecom German Open. Radwańska and Kerber were tied after winning 6 matches each.[111] The players have played one match each on grass and clay, with Radwańska winning both. Kerber leads their head-to-head on hard courts 5–4. Their first meeting in 2015 at Bank of the West Classic took place at night, with Kerber winning in three sets.[112]

Radwańska and Svetlana Kuznetsova played each other eighteen times since 2007, with Radwańska trailing the head-to-head 4–14.[113] Their first meeting was at Wimbledon in 2007 with Radwańska losing in straight sets. She lost their first three meetings, but in the four meetings that eventuated in 2008, she would win three of them, including in the third round of the Australian Open[114] and in the fourth round of Wimbledon.[115] Additionally, she also defeated her at the year-end championships later in the year after replacing an injured Ana Ivanovic during the round robin stage. Radwańska would later struggle in the rivalry, at one point losing six meetings in a row, including an upset loss at the 2012 French Open,[116] before ending this losing streak at the 2014 Mutua Madrid Open, saving three match points in the process.[117] Radwańska also lost to Kuznetsova in the two finals in which they met, first at Beijing in 2009[118] and then at San Diego in 2010.[119] In 2015, Radwańska lost to Kuznetsova again in the opening match of Fed Cup tie between Russia and Poland.[120] Their most recent meeting at the 2016 Wuhan Open saw Radwańska lose a three-set, quarter-final thriller after holding a match point in the second set.[121] They met for the 17th time at the WTA Finals in Singapore, with Radwańska again wasting a match point in a three-set loss.[122] Their most recent meeting, at the 2017 Wimbledon Championships, saw Radwańska lose in straight sets, a decade on from their first meeting.[123]

Radwańska began her tennis career with her father, Robert Radwański, as her coach. She stated: "My dad was traveling with me all my life and we practiced together for 17 years, almost actually 18. So it's pretty long time."[137]

In 2011, Radwańska began working with Fed Cup coach Tomasz Wiktorowski, who replaced her father. Borna Bikić, a veteran coach on the WTA Tour, briefly joined them in 2012.[138]

Radwańska hired Martina Navratilova as part of her team at the conclusion of the 2014 season. In April 2015 they parted ways after Navratilova stated that she was too busy to continue in her part-time role as Radwańska's consulting coach.[139]
