Heather Watson is Britain's new number one after beating Taipei's Chang Kai-chen in the final of the Japan Open on Sunday.

The 20-year-old moves up 21 places to 50 in the world rankings as a result of her success in Osaka while previous number one Laura Robson rises four spots to 52.

I've worked a lot on being more aggressive but I also had to use my defensive skills.

Watson's victory meant she became the first British woman since Sara Gomer 24 years ago to win a WTA title.

"I've worked so hard for this moment my whole career," said Watson. "That's why I practised so hard, ran all those miles and lifted all those weights, for moments like this."

Watson, who saved four match points on her way to a dramatic 7-5 5-7 7-6 victory, added: "The match was so close from start to finish.

"She was playing unbelievably and I just had to hang in there. I've worked a lot on being more aggressive but I also had to use my defensive skills.

"When I was three match points down and she was serving for the match, I just thought 'Oh no'. But I just took it point by point. I don't know how I did it but I did. This ranks as one of the best days of my life."

Attention now turns towards this week's Kremlin Cup which Samantha Stosur is 9/4 to win. Meanwhile, Caroline Wozniacki is 1/1 to win the tournament in Moscow and Marion Bartoli can be backed at 1212/1.
