Heather Watson has taken over as the highest-ranked British woman and there are four players inside the top 100 for the first time in more than 20 years.

Watson rose to No.71 in the new WTA list, the first time she has led the quartet completed by Anne Keothavong (76), Laura Robson (91) and Elena Baltacha (100).

The last time Britain had four women inside the top 100 was on March 12, 1991 with Jo Durie (62), Sara Gomer (89), Sarah Loosemore (93) and Monique Javer (100).

Watson, 20, won the Bank of West Classic doubles title with Marina Erakovic at the weekend.

Watson, Keothavong, Robson and Baltacha have all been named in the GB team for the Olympics. Watson and Keothavong are competing at the Mercury Insurance Open in Carlsbad, California this week while Robson is participating in the Sony Swedish Open.
