Under Kotyza, Kvitová continued to make gradual progress on the Women's Tennis Association Tour and in May 2011 she reached the world"s top ten for the first time, by virtue of winning the Mutua Madrid Open.
In twelve months, Kvitová had gone from World Number.

In January 2016, Kotyza and Kvitová parted ways.
