Cliff Richey, who 40 years ago was the No. 1-ranked American tennis player, the hero of the championship-winning U.S. Davis Cup team and the winner of the first-ever professional Grand Prix points title, in a new book discusses the most difficult opponent of his life, depression.

In "Acing Depression: A Tennis Champion's Toughest Match," Richey calls depression among adult males "the silent tragedy in our culture today" and details his life-long battle with the disease that afflicts approximately 121 million people around the world.

Co-written with his oldest daughter, Hilaire Richey Kallendorf, ACING DEPRESSION (New Chapter Press, www.NewChapterMedia.com) is a first-hand account of the life and tennis career of Richey, providing readers with his real-life drama - on and off the tennis court. Richey's depression is a constant theme, from his genetics and family history, to the tensions of his professional tennis career and family life, to his eventual diagnosis and steps to recover from his condition.

Jimmy Connors, the five-time U.S. Open champion and a friend of Richey's, penned the Foreword.
