When the U.S. Open Tennis Championships get underway at the end of August in Flushing Meadows, N.Y., past winners from Raphael Nadal to Maria Sharapova will be vying for yet another title.

But there will be others looking to make their mark, too.

This year’s U.S. Open also marks the return of a doubles team whose performance last year put them on the map, doubles partners Aisam-Ul-Haq Qureshi, of Pakistan, and Rohan Bopanna, of India. When they’re not on the court, the tandem works to promote peace between their native countries.

Only A Game’s Ron Schachter reports on the tennis duo who call themselves the Indo-Pak Express.
