Welcome to ESPN Insider's 2017 ranking of the top 100 prospects in baseball.
This is my 10th such ranking for Insider. A complete list of the top 100 is below, with a more detailed explanation of the process in determining these rankings also found on each of the player capsule pages.
This year's top 100 was again characterized by a lot of turnover, with 18 first-time appearances in the top 50 alone, and a total of 51 new names added to the 2017 top 100 compared to the top 100 of 2016. Seven of last year's top 20 players and 14 of the top 50 graduated to the major leagues last season, including both Rookies of the Year -- No. 1 prospect Corey Seager in the National League, for his huge season playing shortstop for the NL West-winning Los Angeles Dodgers, and No. 48 Michael Fulmer in the American League, for his 3.06 ERA in 26 starts for the Detroit Tigers.
In this year's top 100, 10 of last year's top 20 prospects have carried over into this year's top 20, and 49 players total out of the top 100 have repeated.
