Watson claimed the first WTA Tour title of her career on Sunday night as she and New Zealand partner battled hard to win in straight sets. The pair had already beaten the second and third seeds on their way to the final, and the duo they beat in the final were ranked seventh and 37th in the world. After breaking three times to win the opening set, Watson and Erakovic fell a break down at the start of the second. They battled back to serve for the match at 5-3 but were broken, then threw away two match points on their opponents" serve, but held firm to take the second set on a tie-break. For Watson, who reached the second round in the singles draw, it was the perfect warm-up for the Olympics, where she will represent Great Britain in the doubles as Robson's partner.

The 17-time Grand Slam champion also tied Sampras" record of seven Wimbledon titles. Federer first became No 1 in 2004 and said it was an "amazing feeling" to be back at the top. "I had set a goal with my team to try and get back to the top of the rankings, but I never thought with the depth in the game this year that I would have been able to get it back so quickly," Federer said. I am extremely proud and honoured to have beaten Pete's record as he was my childhood hero and I have always looked up to him. The Swiss star will enter the Olympics next week as the world's top-ranked player following his four-set win over Andy Murray in the final at Wimbledon, which also will host the Olympic tennis competition. Federer spent 237 consecutive weeks at No 1 between February 2004 and August 2008 and overtook Novak Djokovic atop the rankings with his win at Wimbledon. "Great effort," said Sampras. The hardest thing to do in sports is to stay on top. Roger has been able to do so.
