I don’t have a lot of hope for Roger Federer at the U.S. Open, which begins today. His picture appeared last week on the cover of Sports Illustrated and yesterday on the cover of the New York Times Magazine. The SI cover jinx is the most famous in sports, but it should not be forgotten that the Times magazine, for its special Open issue three years ago, put a beautiful young Canadian on its cover with the words: “Eugenie Bouchard Could Be Tennis’s Next Big Shot.”
