Olympic champion Elena Dementieva will spearhead Russia's campaign at the 2010 Hopman Cup.

Hopman Cup organisers confirmed on Wednesday that the world No.4 and Beijing Olympics gold medallist would partner countryman Igor Andreev in the mixed teams tournament in January.

The 27-year-old Dementieva will be making her Hopman Cup debut at the 22nd edition of the event, which Russia have only won once, in 2007.

"It's great to have one of the game's top women's players, who hasn't been to the tournament," director Paul McNamee said.

"She is very consistent, one of the women who could finish at No.1 at the end of the year and we are delighted that she is coming.

"Elena and Igor are both familiar with team competitions and they will be competitive, no doubt about that."

Dementieva reached a career-high ranking of No.3 earlier this year and recently won her third singles title of the year in Canada.

Andreev is ranked 30th in the world and reached the fourth round at Wimbledon this year.

Australian pair Lleyton Hewitt and Samantha Stosur had already been confirmed for the event.
