India's Sania Mirza is standing on the cusp of history as she is now one win away from becoming world number one in doubles after reaching the final of the WTA Family Circle Cup with partner Martina Hingis. The top seeded pair of Sania and Hingis overcame a second-set lapse to beat Russian girls Alla Kudryavtseva and Anastasia Pavlyuchenkova 6-4 1-6 10-7 in the semifinal. They were up 6-4, 0-2, 30-all, when skies opened up and the resultant break allowed the Russian to regroup. Kudryavtseva and Pavlyuchenkova cruised through the rest of that set, 6-1, and came out firing again in the match to tie-break, going up 4-2. But Sania and Hingis fought hard and made it 7-7. They overcame a bout of nerves to reel off three straight in a row to clinch the issue.
