China's Shuai Zhang  and Chinese Taipei's Chia-Jung Chuang  clinched their first WTA doubles team title on Saturday at the Estoril Open with a 4-6, 6-1, 11-9 victory over third-seeded Kazaks Yaroslava Shvedova and Galina Voskoboeva on Centralito court in 90 minutes.

Zhang said, "This is my first time playing with Chuang, who is a very good doubles player. We were 0-5 down, our opponents played aggressively, but we played one point at a time and made few mistakes. We played a very good second set and in the tie-break."

"I am very happy," said Chuang. "We found our tempo after a slow start, but played better and better as the match went on. I hope we play together again in the future."

Shvedova and Voskoboeva raced into a 5-0 lead, losing just eight points. But Chuang and Zhang fought back to win four straight games, only for Zhang to be broken to 30 in the 10th game of the 38-minute opener.

In a reversal of fortunes, Chuang and Zhang maintained their streak of games by breaking the Kazaks serves three times in 29-minute second set for a Champions tie-break.

Incredibly, Chuang and Zhang battled back from a 1-4 deficit in the Champions tie-break and secured the WTA International Series title on their third championship point.
