Preparing herself for the gruelling hard court season ahead, Sania Mirza advanced to the semi-finals of the USD 50,000 ITF Challenger tournament in Lexington, USA, after Lindsay Lee-Waters withdrew from the contest on Saturday.
The second seed Indian was leading 5-2 in the first set when her American opponent opted out of the quarter-final contest.
Sania will next meet sixth seeded Chinese Meg Yhuan, ranked 195th, who defeated American fourth seed Madison Brengle 6-3, 6-3 in another quarter-final match.
