This is an update of the piece from a year ago: Phillies international signings: their share of major league talent, but no stars
About a quarter of all current production (by WAR) is generated by players who were signed as international free agents (IFAs) — either as teenagers who then rose through farm systems, or established pros ready to step directly onto major league rosters. We’ll review the Phillies’ history in international signings over the last 30 years, and we’ll use total WAR produced to date as a handy, quick measure of major league impact.[1]
