- Groenefeld/Peschke and Dabrowski/Xu are both set to make their debut appearances at the WTA Finals as teams
- The pairs become the sixth and seventh teams to qualify, with only one spot remaining
Groenefeld and Peschke, from Germany and the Czech Republic respectively, will be making their debut appearance as a team at the WTA Finals. Peschke will be contesting the event for the seventh time in her illustrious career, and returns as a former finalist in 2008 (with Rennae Stubbs), 2010 and 2011 (both with Katarina Srebotnik). In 2017 the German/Czech duo won the J&T Banka Prague Open and were runners-up at the Rogers Cup (Toronto), while also making the semifinals at Wimbledon, Volvo Car Open (Charleston) and Porsche Tennis Grand Prix (Stuttgart).
Xu Yifan, of China, and Canada’s Gabriela Dabrowski will both be making their first appearance at the WTA Finals, having begun their partnership in March of this season. In their first tournament together, the pair lifted the title at the Premier Mandatory Miami Open and captured their second title at the Connecticut Open (New Haven), before reaching the quarterfinals at the US Open.
Groenefeld/Peschke and Dabrowski/Xu will join Martina Hingis/Chan Yung-Jan, WTA Finals defending champions Ekaterina Makarova/Elena Vesnina, Ashleigh Barty/Casey Dellacqua, Lucie Hradecka/Katerina Siniakova and Timea Babos/Andrea Hlavackova in Singapore, who all secured their places earlier this season.
