India's Rohan Bopanna, playing with his fourth different partner of the season, joined forces with Marcin Matkowski to reach the doubles semi-finals of the Dubai Duty Free Tennis Championships.
The unseeded Indo-Polish pair knocked out Romania's Florin Mergea and Serbia's Viktor Troicki 6-3, 6-4 in the quarter-finals of the $ 2,617,160 hard court tournament.
This is the second best performance of the season for Bopanna, who won the season-opening Chennai Open with compatriot Jeevan Nedunchezhiyan.
Bopanna and Matkowski had shocked second seeds Ivan Dodig and Marcel Granollers 5-7, 6-3, 11-9 in the opening round of one of the most-loved events on the calender.
Bopanna could next find compatriot Leander Paes in the semifinals if the veteran Indian and his Spanish partner Guillermo Garcia-Lopez could go past third seeds Daniel Nestor from Canada and Frenchman Edouard Roger-Vasselin.
There is no Indian competing in the singles. Prajnesh Gunneswaran had lost in the first round of the Qualifying event, suffering a 2-6, 2-6 defeat against Romania's 124th ranked Marius Copil.
