PRAGUE (AFP) - Reigning US Open women's doubles champions Andrea Hlavackova and Lucie Hradecka of the Czech Republic revealed today they are going separate ways after five good years together.

"It was Andrea's decision... she told me she wanted to play with Lucie Safarova next year and focus on singles," the 28-year-old Hradecka told the www.tennis-arena.cz website.

"I don't think it will be a problem to play in the Fed Cup together," added the 27-year-old Hlavackova.

The Czech Republic won the Fed Cup in 2011 and last year.

Before lifting the US Open trophy this year, Hlavackova and Hradecka had won the French Open in 2011.

They were also runners-up at Wimbledon, the US Open, WTA Tour Championships and London Olympics in 2012.

Hlavackova will team up with Czech left-hander Safarova while Hradecka will join forces with Michaella Krajicek, a Dutch player with Czech parents.
