- Switzerland captain Severin Luethi will tap the star power of Roger Federer and Stan Wawrinka when the Alpine country faces Italy in next month's Davis Cup, Swiss Tennis announced Wednesday.

World number three Federer and number four Wawrinka will team up with Marco Chiudinelli and Michael Lammer, 167th and 454th respectively in the ATP rankings.

Federer and Wawrinka had already confirmed that they planned to take part in the September 12-14 matches in Geneva, but Luethi's official announcement was required to make that formal.
