Teen tennis sensation Sania Mirza touched a career-high ranking of 72, climbing one spot, in the latest WTA rankings released on Monday.

The Indian ace, who has received a wild card to play in the French Open, is recovering from an ankle injury which forced her to miss India's campaign in the recent Fed Cup tennis tournament.

The 18-year-old, who turned professional in 2003, is fast catching up with Thailand's Tamarine Tanasugarn, who is ranked 68.

Sania has a win-loss record of 10-4 this year, with career prize-money earnings of US $129,109.

Despite the nagging injury which troubled her, the year saw Sania win her first WTA title in Hyderabad after putting up a brave fight against eventual winner Serena Williams in the third round of the Australian Open.

In March, she upset of No.4 seed Svetlena Kuznetsova in the Dubai Open. Her last tournament was as a wild card in Miami, where she lost to Sanchez Lorenzo in the first round.
