Elena Vyacheslavovna Dementieva born October 15, 1981, Moscow, is a professional tennis player from Russia.
Dementieva is a fast, powerful and aggressive baseliner known for her outstanding offensive and defensive abilities off the ground. Her forehand in particular is a fearsome weapon due to the power and placement of the shot and her ability to flatten it out. However, her serve is very inconsistent and considered one of the worst on the WTA Tour, especially in tight situations.
Dementieva was the seventh-seeded player at the Tier I Qatar Telecom German Open in Berlin but reached the final, where she lost to thirteenth-seeded Dinara Safina. Dementieva defeated fourth-seeded Janković in the quarterfinals and second-seeded Ivanović in the semifinals. Dementieva's win over Ivanović was her fourth in four career matches with Ivanović.
