Keith Woolner on peak age

By Tangotiger, 12:55 AM

Written in 1997:

The first study looked at all players who played 10 or more years in the majors (no AB minimum required).  For each, I looked at the maximum number of adjusted batting runs they had in any season. ... The age at which the player attained his highest ABR total is defined as his peak year.... Conclusion: For players who will have significantly long careers, the most common age to peak is age 27, with 25-28 being the most likely range for a peak year.  By age 31, over three-quarters of all such players will have seen their best year come and go.
