Terrible start for Petra Kvitova

— -- By all accounts, Petra Kvitova was supposed to challenge for Grand Slam titles, if not the No. 1 ranking. At least that's what we thought after she stormed out of the All England Club in 2011 with a title in tow. A few months later, Kvitova would end the year in as much of a groove as anyone in recent memory after she beat down the field at the WTA Championships without losing a match and then won Fed Cup. It looked as if she was the fresh face who was leading the charge to a new era of women's tennis.

But the spotlight became too unsettling for her. The shy, introverted Kvitova never felt comfortable when newfound fame came barreling at her before she was ready to embrace it.
