Errani and Vinci have been 2014's outstanding team, winning the Australian Open and topping the Road To Singapore standings on the back of a dominant clay court campaign.
They have carried this form with them to Roland Garros, where they were champions in 2012, dropping a combined total of four games in their quarter and semifinal engagements. When they raced into a 3-1 lead in the opening set against Hsieh and Peng, another one-sided encounter looked on the cards.
However, from this point on, the Italians would win just two more games as Hsieh and Peng turned the match on its head. Skillfully pinning the Italians back with a mixture of aggressive returning and a series of precise lobs, the top seeds took the initiative and with it the set. With Errani's serve looking particularly vulnerable, Hsieh and Peng piled on the pressure in the second, breaking three more times to wrap up a 6-4, 6-1 victory.
"I think at the beginning of the match we were really, really nervous and tight," Peng said. "I think they also played really good at the start, but then at some point, when we were 3-1 down, I think, we started to relax.
"We were telling each other, 'We can't be tight anymore, because they're a really good team. We need to do something.' Maybe we just stopped thinking about winning or losing, you know, and just tried to play our tennis."
Hsieh and Peng's only other major triumph came at last year's Wimbledon and their thoughts are already turning to defending this crown.
"For sure we're going to go celebrate tonight, but we don't know where yet," Peng added. "Then we'll have a few days rest before we start preparing for Wimbledon, you know.
"What celebration? Nothing big, as we have a lot of tennis to come this summer so we cannot do something too dangerous. We are not going to get injured before Wimbledon!"
