Azinger was the U.S. Ryder Cup captain for the 2008 at Valhalla Golf Club in Louisville, Kentucky. He led the team to its first victory over the European squad since 1999. The team's victory was largely credited to his innovative strategy. This strategy is outlined in his book, "Cracking the Code: The Winning Ryder Cup Strategy: Make it Work for You", which was released in May 2010. The book was co-authored with Ron Braund, a corporate team builder and psychologist, who consulted Azinger throughout the Ryder Cup.
