Dementieva falls to Oudin

Women’s fourth seed Elena Dementieva became the first big-name casualty of the 2009 US Open when American teenager Melanie Oudin claimed another grand slam scalp today.

Oudin, 18 later this month, had caused a shock at Wimbledon earlier this summer when she knocked out Jelena Jankovic in the third round and the world number 70 added the 2008 Olympic champion to her list of victims at Arthur Ashe Stadium with a 5-7, 6-4, 6-3 upset victory.
