The Russian faces Agnieszka Radwanska for the title on Saturday after the Pole beat Victoria Azarenka of Belarus 6-3, 4-6, 6-2 under a setting sun in the second semifinal.
Zvonareva tore through the first set tiebreak, a weak forehand volley into the net by Kvitova gift-wrapping it to the Russian 7-2. The second set was embarrassingly one-sided, Kvitova appearing in a hurry to reach the locker room as she dumped another backhand into the net on match point.
"I don't know what happened," a dejected Kvitova said.
