Bopanna with French partner Edouard Roger-Vasselin reached the semifinals at the grass court Grand Slam, losing to eventual winners Mike and Bob Bryan.
"It is an extremely proud moment for my team and myself, as this ranking is a true testament of the many years of hard work, focus and determination. Being for the first time, the highest ranked Indian makes this all that more special and is an added motivation to perform better with every passing game," Bopanna said.
"It is too early to speculate, though Eduardo and I are in conversation on continuing this partnership given the great run we have had in the two weeks at Wimbledon," he said.
Following Bopanna at number six is his regular partner for 2013 season Mahesh Bhupathi, who also lost in the quarter-finals in London with Austrian partner Julian Knowle.
