tennis star Sania Mirza and her Czech partner Lucie Hradecka fritted away a great opportunity to lose the Dubai Tennis Championships doubles semifinal here. After dominating the first set, Sania and Hradecka lost 6-2 2-6 7-10 to Lyudmyla Kichenok of Ukraine and Latvia's Jelena Ostapenko on Friday night. The Indo-Czech duo, which had received a wild card for the tournament, saved 11 break points while converting two of the three in the first set to take a 1-0 lead in the WTA 500 tournament. However, the two were unable to keep the momentum going as Kichenok and Ostapenko levelled the proceedings in the second set and then eventually sealed the match in their favour.
