Lost 6:2, 6:4. They were a bit unlucky not to have broken in the second for 5:4 after being 2:4 down, but I guess it wasn't meant to be. Overall their opponents were quicker, better prepared and more organized, I'm guessing they've been playing doubles together more often than Martic/Zheng. They had solutions for virtually every major situation, efficiently targeting right under the feet of Martic/Zheng or into their bodies quite often. The better team definately won today althogh Martic/Zheng have put in a decent fight in the 2nd set.
In general, I wouldn't call this week a great success story for Petra, but it's a solid start to this mini tour. Good luck in Taipei
