J.J. Cooper of Baseball America put together a list of the youngest player at each minor-league level, which is always useful when evaluating the performance of a prospect relative to his competition.
He also included the youngest players in the majors and what stood out to me is this: Bryce Harper is still the youngest player in the National League.
Harper has three seasons and more than 1,500 plate appearances of experience in the big leagues, including two All-Star games and a Rookie of the Year award, and he’s now the No. 3 hitter on a team many people pick to win the World Series. He’s also just 22 years and 176 days old. Even if Harper were an entire year older he’d still be one of the 10 youngest players in the league.
Blue Jays pitchers Roberto Osuna (20 years, 62 days) and Miguel Castro (20 years, 107 days) are the two youngest players in the American League.
