London, July 7: India's Divij Sharan and his New Zealand partner Artem Sitak survived a tough five-set battle to enter the third round of the men's doubles category at the Wimbledon tennis tournament here on Saturday. The unseeded Indo-Kiwi combination had started poorly as they lost the first couple of sets to Julio Peralta of Chile and Argentina's Horacio Zeballos. But Sharan and Sitak made a superb comeback, winning the next three sets to carve out a 6-7, 4-6, 6-3, 7-6, 6-4 victory in a gruelling contest which lasted for three hours and 22 minutes. They will face Jonathan Erlich of Israel and Marcin Matkowski of Poland. IANS
