I was idly wondering whether winning one's first slam final versus losing one's first slam final tends to suggest that a player will win more slams in the future. Del Potro, of course, counts as a player who won his first slam final. Others are Roddick, S. Williams, Federer and Nadal. Current players who have lost their first slam final are Murray, Gonzalez, Baghdatis, Djokovic, Tsonga, V. Williams. Who am I missing? Is there any relationship?
