Top 100 MLB Prospects Updated For May 2018
A month into the season, we’ve released our first significant in-season update to reflect reporting we’ve done since the season began.
This list will have some further significant changes coming at the top over the next month as No. 1 prospect Ronald Acuna and No. 2 prospect Shohei Ohtani both get closer and closer to graduating. No. 3 prospect Vladimir Guerrero Jr. is continuing to put up spectacular numbers for Double-A New Hampshire, so the No. 1 spot will be in good hands after Acuna and Ohtani graduate as well.
The adjusted rankings welcome a number of players to the back of the Top 100 including Indians righthander Shane Bieber. Bieber continues to impress scouts with impeccable control to go with better stuff than he showed in college.
Baseball America will update its Top 100 Prospects ranking at the start of each month during the season, from April through August. In between those updates, we will also adjust the Top 100 to account for graduated prospects.
As always, position players are eligible for the Top 100 Prospects if they have not exceeded 130 big league at-bats. Pitchers may not exceed 50 big league innings to be eligible, while relievers may not exceed 30 relief appearances.
