Major League Baseball faces a potential lockout in December 2026. Players and management have long clashed over salary cap proposals, a format that union head Tony Clark criticizes as harmful to competition and player salary guarantees. Commissioner Rob Manfred argues the cap could address payroll disparities as MLB also tries to deal with declining revenue from regional sports networks. Teams like the Dodgers and Mets have pushed payrolls to record levels, highlighting disparity. Baseball’s collective bargaining agreement expires in December 2026, and past negotiations have led to nine work stoppages.
