How it was won
Sora Matsushima and Hina Hayata won WTT Champions Frankfurt. Matsushima, who was unseeded and had lost the Montpellier final a week earlier, beat Dang Qiu 4-1, 11-8, 15-13, 11-13, 18-16, 11-9. Hayata beat the top seed, Miwa Harimoto, 4-3 in an all-Japanese women's final, 11-4, 11-8, 4-11, 6-11, 11-6, 9-11, 11-9.
The men's top three seeds were gone before the quarter-finals: Anton Källberg beat Truls Moregard 3-0, Simon Gauzy beat Hugo Calderano and Dimitrij Ovtcharov beat Tomokazu Harimoto. Japan had three of the four women's semi-finalists, and there was no Chinese player in the quarter-finals.
