Welcome to the 2011 ESPN.com ranking of the top 100 prospects in baseball.
This is the fourth year I have done these rankings for ESPN. The three previous top-ranked prospects -- Evan Longoria (2008), Matt Wieters (2009) and Jason Heyward (2010) -- have all established themselves in major league starting lineups. The top five players from the 2010 rankings and 10 of the top 15 -- including two who played huge roles in the postseason, San Francisco Giants World Series hero Buster Posey (#4) and Texas closer Neftali Feliz (#13) -- have graduated to the big leagues.
A more detailed explanation of the process in determining these rankings is found at the top of each of the four player capsule pages.
