Baseball America's Top 10 Prospects lists are based on projections of a player's long-term worth after discussions with scouting and player-development personnel. All players who haven't exceeded the major league rookie standards of 130 at-bats or 50 innings pitched (without regard to service time) are eligible. Ages are as of April 1, 2011.

This is Baseball America's 22nd annual Top 100 Prospects list,our definitive annual ranking of the best professional talent in baseball below the major league level and the culmination of our offseason prospect coverage.Our focus this year is on the Split Decisions throughout the list—those points where our voters disagreed.

You'll find those highlighted throughout the next seven pages, with people explaining their why they voted the way they did. Six people contributed to the voting this year: Co-Editors Will Lingo and John Manuel, executive editor Jim Callis, managing editor J.J. Cooper, associate editor Matt Eddy and assistant editor Conor Glassey. Each person compiled a top 150 list, and we then reviewed the composite numbers and made adjustments before locking down the final list. The rankings follow our standard prospect guidelines, which means any player who has not exceeded 130 at-bats, 50 innings or 30 appearances in the major leagues (without regard to service time) is eligible.

We're focusing on the best tool for each player, handing out a best-case grade on the 20-80 scouting scale—where 20 is the worst, 80 the best, and 50 major league average. Ages are as of March 31, and ETA is the year we expect the player to establish himself as a big leaguer.
