Chuck Berry has over 30 years of experience representing professional baseball players in their contract negotiations, arbitration, free agency and career development. He went straight from law school to working with one of the icons of the sports agent business, Tom Reich and later worked with the sports industry leader, IMG. In 1992, Chuck formed his own company, Champions Management and continued his representation business until 2012 when he decided to retire. During his career, he worked with over 150 players including Hall of Famer, Joe Morgan, Kent Tekulve, Julio Franco, Ruben Sierra, Jack Clark, Jeffrey Leonard, and Manny Sanguillen to name a few.

Ellie Rodríguez began his professional baseball career in 1964 when he was signed by the Kansas City Athletics as an amateur free agent. On November 30, 1964, he was drafted by the New York Yankees from the Athletics in the 1964 first-year player draft. Rodríguez spent the next few years moving up the Yankees farm system, eventually making it to the AAA-level Syracuse Chiefs in 1967. A year later, Rodríguez made his major league debut for the Yankees.
Rodríguez is now a player development consultant for The Atlantic League of Professional Baseball and is in charge of scouting Latin America for the league. He was later announced as manager for the 2018 Road Warriors, a traveling team that will temporarily replace the folded Bridgeport Bluefish in the Atlantic League.
