India's Rohan Bopanna and his Dutch partner Matew Middelkoop lost to the British-Finnish pair of Llyod Glasspool and Harri Heliovaara in straight sets in the Hamburg Open final. The fourth-seeded Indo-Dutch duo, who reached the French Open semifinal this year, failed to break the unseeded pair of Glasspool and Heliovaara even once to suffer a 2-6 4-6 defeat in a match that lasted a little more than an hour.
