MIAMI (Reuters) - World number two Li Na finally made her first appearance at the Sony Open on Sunday, taming Madison Keys in an unsteady effort while three-time champion Venus Williams was also made to work under a blazing Florida sun for her spot in the fourth round.
Li displayed some signs of rust in her first match of the tournament after receiving an opening round bye and a walkover when Alisa Kleybanova withdrew from their second round meeting with illness.
