Prospect rankings update: Who is the new No. 1?

How soon could the Dodgers' Cody Bellinger and the Cubs' Eloy Jimenez be in the major leagues? Allan Henry/USA TODAY Sports

Now that all full-season leagues are underway, here’s an update to my rankings of the top 50 prospects in baseball, my first one since the full offseason top 100 ran in January.

For in-season updates, I rank only the prospects who are currently in the minor leagues, which took out seven players on major league rosters, including three -- Andrew Benintendi, Dansby Swanson, and Josh Bell -- who have also exceeded the 130 at-bat cutoff and will no longer be on any of my prospect rankings.

This is an update rather than a re-ranking. The order of players has barely changed beyond moving players up to fill in for the ineligible names, so for each player I’ve given a quick synopsis of anything that has happened since January, where the player is right now and what I think the rest of the season might look like.
