NEW YORK (AP)—Former tennis player Cliff Richey describes his struggle with depression in a new book.

``Acing Depression: A Tennis Champion's Toughest Match'' is due out next month. He wrote it with his daughter, Hilaire Richey Kallendorf, a college professor.

Richey led the United States to the Davis Cup title in 1970.

Richey's clinical depression was not diagnosed until just before his 50th birthday during a routine visit to the skin doctor. He has since become an advocate for mental health, speaking at events across the country.
