Defiant Serena vows to reassert her supremacy

Defiant Serena Williams insists her shock Wimbledon exit won't herald the end of her reign as the dominant force in the women's game.
Williams crashed to her earliest exit at Wimbledon for nine years as the world number one suffered a shock 1-6, 6-3, 6-4 loss against French 25th seed Alize Cornet in the third round on Saturday.
Top seed Williams, a five-time Wimbledon champion, had reached at least the last 16 in each of her previous seven visits to the All England Club, but Cornet fought back from a set down to end that sequence in two hours and four minutes of gripping drama on Court One on Saturday.

It was the shell-shocked 32-year-old's earliest Wimbledon exit since her loss to Jill Craybas at the same stage in 2005.
Serena could have no complaints about an embarrassing defeat which continued a disappointing campaign for the 17-time Grand Slam champion, who has failed to get beyond the fourth round at any of the three majors so far this year.
Serena had arrived in south-west London desperate to make amends for her shock first round exit against Garbine Muguruza at the French Open last month, a chastening result which followed her Australian Open fourth round defeat against Ana Ivanovic.

But she is convinced her poor form in 2014 isn't a sign that she is finally on the way down after over a decade as the sport's pre-eminent power.

"In Australia I just couldn't play. And Paris I played really bad. Here I actually thought I played better. I came into the tournament in better form," Serena said.
"I thought I was doing pretty decent. I'm going to have to watch this film and see what I can do better and what went wrong.
"It's okay. Sometimes it happens. You work hard, maybe it's not for today, maybe it's for tomorrow. I just got to keep going.
"It's happened to me a few times. But it's fun. It kind of gives you a mission to work on, gives you goals to work towards to kind of see what you can do to do better.
