The former world tennis number one Roger Federer says he'll play for Switzerland in their Davis Cup quarter-final with Kazakhstan in early April.
The 32-year-old, for whom the Davis Cup remains one of the few major titles to elude him, played in last weekend's 3-2 victory over last year's finalists Serbia.
Federer, ranked eighth in the world, and Stanislas Wawrinka, ranked third, should have more than enough firepower to beat Kazakhstan, who edged Belgium in their first round tie.
