When she feel like she is not able to come back in the game, she just retires.. Wang yihan retires 12-21, 3-11
Anyway, even if WYH fights back to force the decider,she will still lose the match. So better not risk aggravating her injury.
For the third time this year LXR won back-to-back titles, but I think her first time winning back-to-back SS titles.
For the time being in team events, I would count on WYH more as she is superior to LXR in terms of mental strength and experience.
