MELBOURNE Jan 15 Li Na struck back for the older generation of women's tennis by fending off gutsy 16-year-old qualifier Belinda Bencic 6-0 7-6 (5) to reach the third round of the Australian Open on Wednesday.
Swiss Bencic, who knocked out Japan's Kimiko Date-Krumm, the oldest woman in the draw in the first round, lost seven straight games before steadying to surprise the Chinese fourth seed with her tenacity in a tense second set played out in stifling heat at Rod Laver Arena.
Taken deep into the deciding tiebreak, Li sealed the match by crunching a backhand winner down the line.
Li will next face qualifier Lucie Hradecka or another Czech in 26th seed Lucie Safarova.
