Rusty Li bears down to vanquish Keys

World No 2 Li Na finally made her first appearance at the Sony Open on Sunday, taming Madison Keys in an unsteady effort.

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.

She had to fight off three set points and an early break in the second set before clinching a 7-6 (3), 6-3 win over her American opponent.
