Note: While the entire baseball season was cancelled in 2020 due to the COVID-19 pandemic, the SCIAA did not hold a Somerset County Tournament in 2021, due to what the SCIAA considered was too short a season for proper tournament seeding and qualification, and availability of TD Bank Park for semifinals and finals.
