Projections-Fueled Top 25 Pitching Prospects Entering 2025

Continuing an annual tradition, this article ranks the top 25 starting pitching prospects by peak projected MLB ERA heading into 2025 (skip to the bottom for the ranking!)
Like the other projection systems at FanGraphs, my projections capture the usual ingredients: past performance weighted by recenecy, regression to the mean that accounts for a player’s probability of making the major leagues, major league equivalencies to adjust for minor league difficulty, aging, park effects, and league scoring environment. The peak projections make use of aging curves to translate a player’s forecast to a late-20s peak forecast. Regardless of where the “true” peak age is, there is broad consensus that most growth happens in the teen years and early-20s, however.
