The first round of doubles had two upsets - No.3 seeds Jill Craybas and Mandy Minella were one.
The other upset saw the Pliskova twins beat No.1 seeds Anna-Lena Groenefeld and Janette Husarova.
Groenefeld and Husarova pushed the match to a match tie-break but ended up falling in it, 10-4.
Other first round winners included Valeria Solovyeva and Raluca Olaru, who beat a Polish team.
Eva Birnerova and Irina Buryachok were also winners - Buryachok on the left, Birnerova on the right.
The Czech-Ukrainian pairing defeated another Polish team, Paula Kania and Sandra Zaniewska.
The No.2 seeds also won their opener - Mervana Jugic-Salkic on the left, Shuko Aoyama on the right.
Their opponents - Eva Hrdinova on the left, Gabriela Dabrowski on the right - put up a fight...
But Aoyama and Jugic-Salkic were just too tough on the day, winning a see-saw encounter, 62 16 105.
Karolina Pliskova looked on during she and her sister's quarterfinal loss to Olaru and Solovyeva.
And the Polish team of Alicja Rosolska and Marta Domachowska also won its quarterfinal match.
Then two more upsets - Birnerova and Buryachok beat No.4 seeds Renata Voracova and Klara Zakopalova.
And Lara Arruabarrena and Lourdes Domínguez Lino took out No.2 seeds Aoyama and Jugic-Salkic.
Domachowska and Rosolska were crowd favorites in their semifinal against Olaru and Solovyeva...
But Olaru and Solovyeva kept their run going, scoring a 62 62 win and moving through to the final.
Birnerova and Buryachok fell in the other semifinal to Arruabarrena and Domínguez Lino, 60 63.
Sunday's final saw both teams plot and strategize as much as they could, as is in the doubles realm.
And Olaru - formerly one of the WTA's brightest rising stars, now on the way back up - was ready.
But Arruabarrena and Domínguez Lino were too sharp in the big moments, and would eventually win.
Spanish duos have won 34 WTA doubles title since the start of 2000 - second only to the US with 55.
