What happened to Shao-Xuan Zeng? He won that first round match in Shanghai and jumped up to a respectable ranking and hasn't played a match since. He was doing well with Yu in doubles winning some challengers and then they stopped playing together as well. Anyone know what's going on, like maybe he retired or is injured?
I can only guess that zeng is injured. yu played doubles with gao and zhang the last couple of tournaments.
