MLB Sues Insurance Providers Over COVID Losses

The MLB faced significant financial losses due to the COVID-19 pandemic, with the 2020 season largely played without fans and over 1500 games canceled. Despite having paid for comprehensive insurance policies to safeguard against such economic losses, MLB claims that insurers AIG, Factory Mutual, and Interstate Fire and Casualty have not honored their contractual obligations. Consequently, MLB has filed a lawsuit involving various entities, including the Baseball Commissioner's Office and MLB Network, to seek compensation.
