Li pulls out of Qatar Open

Australian Open runner-up Li Na decided to pull out of next week's Qatar Open, citing an ankle injury she suffered in the final in Melbourne last month.

The 30-year-old world No. 5 Li is a two-time Aussie Open finalist and captured a French Open title in 2011.

American Venus Williams withdrew from the Qatar tournament earlier this week, citing a back injury.

The Doha field, however, still features nine of the top-10 players in the WTA rankings.
