Ying-Ying Duan – New Chinese player in WTA top 100 – 1st Service
Ying-Ying Duan (*89 / CHN) can be at her age of 27 years hardly considered as a young tennis prodigy, but this relatively new entrant into the WTA top 100 could eventually become a factor in the women's tennis. At her height of 186cm (6'1''), the service can be considered as her biggest weapon. Her service surely has already quite some potential, but certain improvements could bring even better serving efficiency and higher margin along.
