McGinnity began the 1902 season with the Orioles. However, the franchise began to fall into significant debt. Joe Kelley, star player for the Orioles and son-in-law of part-owner John Mahon, reported that the team owed as much as $12,000 ($354,600 in current dollar terms). Unable to afford that debt, Mahon purchased shares of the team from Kelley and player-manager John McGraw. With this, Mahon became the majority shareholder. On July 17, 1902, Mahon sold his interest in the Orioles to Andrew Freedman, principal owner of the Giants, and John T. Brush, principal owner of the Cincinnati Reds, also of the NL. That day, Freedman and Brush released McGinnity, McGraw, Kelley, Roger Bresnahan, Jack Cronin, Cy Seymour, and Dan McGann from their Oriole contracts. Brush then signed Kelley and Seymour to the Reds, while Freedman signed McGinnity, Bresnahan, Cronin, and McGann, joining McGraw, his new player-manager, on the Giants. McGinnity attempted to contact Johnson that night, offering to stay with the Orioles if he could receive Johnson's personal assurance that he was welcome to stay. McGinnity did not hear back from Johnson, who had left his phone off the hook that night to avoid being contacted, and joined his teammates with the Giants.
