 Barbara Krejcikova is the women's single champion at Wimbledon. For the 28-year-old Czech, the victory was a reward for overcoming injuries and periods of self-doubt that followed her first major victory, which came at the French Open three years ago. Krejcikova prevailed in a rollercoaster battle that tested the nerve of both players, finally closing out a near two-hour battle 6-2, 2-6, 6-4.
