There’s been a lot of stories to be had this season, but what’s really ran the course of the season is the youth movement that’s being served. Yet another highlight of it was served when the Chicago Cubs made a long-term deal with Starlin Castro, putting away the 22-year-old until nearly his 30th birthday last week. That follows on the heels of the rise of the Washington Nationals, Oakland A’s and Pittsburgh Pirates, all pushed by young pace-setters that have shook up the establishment in both leagues this year.

However, when it’s broken down, who really are the best of the best when it comes to baseball’s precocious youngsters? While previous early bloomers such as Ryan Braun, Robinson Cano, Miguel Cabrera, Joey Votto and Justin Verlander are moving out of the youth movement stage and into perennial standard bearers, the more recently debuted ballplayers are arguably making the biggest impact of any age group across the game. So in my most recent leap of ranking-based faith, here are the 25 best players 25 years or younger in the game today.

Before we get started, here’s a few guys just claimed by their 26th year but who would’ve definitely found a spot on this list a year ago: Felix Hernandez, Mark Trumbo, Yoenis Cespedes, Yu Darvish, Evan Longoria, Todd Frazier, Gio Gonzalez and Jordan Zimmermann.
