Wimbledon 2013: Heather Watson is latest Briton to be knocked out after 6-3 7-5 loss to Madison Keys Despite warm support from the crowd on Court No. 2, Watson was overpowered by a woman who stands a head taller and serves 10 per cent faster - which is a sizeable margin at this level. Keys is still only 18 years old but she has already climbed to No. 52 in the world and is making a name for herself with her muscular game. One of her backhands came in so quickly that Watson could not dodge out of the way and ended up playing a French cricket shot. Keys broke in the third game of the first set, threading another ferocious backhand up the line for a winner. And then she simply held onto her lead through judicious use of her serve, which touched 117mph at one point. The second set was more topsy-turvy. Watson scored her first breaks of the match and took an early lead, only to be pegged back to level terms as the likelihood of a tie-break loomed. Unfortunately, she was then broken in the 12th game with the help of some abject ill-fortune. Keys hit two balls into the net cord in that game, which both dropped for unreachable winners, and also produced a short angled forehand that seemed to come off the frame. Overall, though, Watson could not claim to have been hard done by, as she won only 45 per cent of the points to Keys's 55. She will thus lose the 160 points she earned by reaching the third round of last year's Wimbledon, which is likely to mean she drops around 10 places from her current position of No. Watson's defeat was the fifth in five appearances from Britain's women at this event, with Laura Robson and Tara Moore still to come. James Ward and Kyle Edmund also went out on the first day.
