BEIJING (AP) — Two days after announcing the end of her momentous tennis career in an open letter to friends and fans, Li Na entered her farewell news conference with the appearance of somebody who had been crying. After the surgery in July, I tried very hard to recover, hoping I can make it to participate in tennis matches in China especially the Wuhan Tennis Open which is the first ever big tennis match in my hometown, Li said. Li set a host of milestones, including being the first Chinese player to win a WTA title, the first to break into the top 20 and the first player from Asia to win a tennis major.
