Someone here in the forum always say, someone loses because he wears a cap. I think he may be vindicated now. LOL. -- Want to play better? Lose the cap, says Murray Tue 20 Jan, 04:18 AM MELBOURNE (AFP) - Britain's Andy Murray reached the top of world tennis with intensive training, working year-round with his team of coaches and physios. And he's taken off his cap. Since losing the ever-present white headgear, the world number four says he's in the form of his life. "I don't know, it's just something that I changed. Since I stopped wearing a cap, I've played much better," he mused after making the Australian Open second round on Tuesday without a hat despite blinding sun. Murray has remained hatless in recent months as he became tennis's hottest property, beating Rafael Nadal and Roger Federer and being named the bookies' favourite for the Australian Open title. "I used to always wear a cap for matches, and didn't used to practice with one really at all. I wanted to get a bit more sort of continuity in what I was doing," he said. "I just felt like when I was playing, if I had really long hair I would still wear a cap because it would obviously get in my eyes. "But when I'd keep my hair short, I don't think it doesn't make a huge difference. Even when the sun's there, the cap doesn't really protect you that much." Novak Djokovic is the only top-four player who regularly wears a cap, with Federer and Nadal usually staying bare-headed. Cap-wearing Andy Roddick's last Grand Slam win came in 2003, while Lleyton Hewitt, who famously prefers his hat backwards, has slid down the rankings to 70.
