Open, she only reached the second round. Nevertheless, Flipkens had success in doubles in 2017. In the first week of the season, she reached a semifinal, partnering with Jeļena Ostapenko. After a disappointing second-round loss at the Australian Open, she made the final of the Nuremberg Cup, partnered with Johanna Larsson, losing a tense match against Melichar and Smith. She then reached quarterfinals of the French Open, partnering with Francesca Schiavone. After that, she debuted in the top 50, getting to No. 43. Things get even better during the grass-court season, when Flipkens won her second career-doubles title, winning the Rosmalen Grass Court Championships alongside Cibulková. She then partnered with Sania Mirza at Wimbledon, where they got to the third round. After subsequent unimpressive results, she finished the year making the final at the Luxembourg Open. 2022–23: Retirement in singles, 6th and 7th doubles titles She announced that Wimbledon would be her last ever singles tournament. She lost in the second round to Simona Halep in straight sets, after leading by a break in both sets. However, she won her seventh title on WTA Tour at the Hobart International alongside Laura Siegemund, with whom she had also won her sixth title at the Transylvania Open in Cluj-Napoca in October 2022. National representation Fed Cup / Billie Jean King Cup In September 2006, she replaced the injured Kim Clijsters as the second member of the Belgian Fed Cup team in the final against Italy, alongside Justine Henin-Hardenne. Flipkens lost both her singles matches (against Schiavone and Santangelo). She and Henin-Hardenne then played the decisive doubles together, but had to retire in the third and final set due to Henin-Hardenne tearing a muscle in her leg, which led to Belgium losing the final with 2–3. During the 2015 Fed Cup, she and her teammates failed to bring Belgium back to the World Group II after the team lost their final tie against Croatia. In 2016, Flipkens was part of the Belgian Fed Cup team against Serbia as the two nations were competing for a spot in World Group II. As Belgium's second player (after Yanina Wickmayer), Flipkens played two singles matches. She lost the first one against Aleksandra Krunić, but beat the 18-year-old Ivana Jorović in the decider, and with this victory ensured Belgium of a place back into World Group II after three consecutive years in the Europe-Africa Zone I.
