The Swiss tennis federation says Federer confirmed Wednesday that he intended to play in the Feb. 10-12 series in Fribourg, Switzerland.
The 16-time Grand Slam singles champion has not played a first-round match since 2004. He said last month he helped to choose the clay court surface for the match against the U.S., believing it would play to the Swiss team’s strengths.
Federer showed his renewed commitment to the Davis Cup when traveling to Australia to help Switzerland win a playoff in September.
Federer also plans to play for Switzerland in the London Olympics this summer.
