Marino spent three seasons in the
Arizona Diamondbacks and
Baltimore Orioles organizations and pitched for five different minor league teams: the
Delmarva Shorebirds,
Aberdeen Ironbirds, Arizona Complex League Diamondbacks,
Quebec Capitales, and
Joliet Slammers. Marino has stated he experienced substandard working conditions as a minor league baseball player. He was the Executive Director of Advocates for Minor Leaguers, a non-profit labor advocacy organization. Marino served as lead negotiator for the
United Football Players Association during its negotiations with the
United Football League prior to and during the
2025 UFL season. Marino successfully negotiated a new collective bargaining agreement between the two sides that the UFPA ratified April 18, 2025, and indicated an intent to shift the relationship between the two entities, which had grown increasingly hostile during negotiations after the UFPA had taken over from the United Steelworkers, toward a more collaborative effort in hopes of ensuring that the historically unstable and unprofitable business of
spring football would have a long-term future. == References ==
