Serbia's Novak Djokovic and Janko Tipsarevic have finished their doubles campaign at the Cincinnati Masters after failing to overcome a tough opener against Lukasz Kubot and Marcelo Melo. Kubot and Melo, seeded at No.
2, saw off the Serbian wildcard duo 6-2 6-3 in exactly an hour of play to progress into the round-of-16. Djokovic and Tipsarevic paid the price for blowing three consecutive game points in the second game as Kubot and Melo got off to a quick 3-0 first set lead.
Djokovic and Tipsarevic once again failed to capitalize on their chances as they lost the first set on a deciding point after blowing four consecutive game points in the eighth game. Kubot and Melo were threatening early on in the second set as well but Djokovic and Tipsarevic saved a break point in the second game to avoid going down by an early break.
However, Kubot and Melo kept pressing as they broke the Serbian duo in the sixth geme and then held on to their serve to clinch the win. Kubot and Melo had a great serving display as they won 93 percent of their first serve points and didn't face a single break point in the match.
Djokovic, 32, and 35-year-old Tipsarevic were playing together for the first time since making the Montreal Masters semifinal in 2005.
