In 2012, Kvitová made the semifinals of the Australian and French Opens, and was crowned US Open Series champion. That same year, she also won the Hopman Cup alongside Tomáš Berdych. In 2014, she won her second and most recent Grand Slam title at the Wimbledon Championships, defeating Eugenie Bouchard in the final. In 2015, Kvitová achieved the feat of making the quarterfinals at all four Grand Slams during her career after advancing to her first quarterfinal at the US Open, where she lost to eventual champion Flavia Pennetta. In 2016, she won the WTA Elite Trophy in her first appearance at the tournament, thus becoming the first player ever to win both categories of year-end championships on debut. In 2019, she reached her first Grand Slam final in almost five years, at the Australian Open where she finished runner-up to Naomi Osaka.
