In an unprecedented MLB event, catcher Danny Jansen will play for both the Boston Red Sox and Toronto Blue Jays in the same game, which was suspended in June and resumes on Monday. Jansen started the game for Toronto but was traded to Boston in July. This unique situation has drawn significant attention, with the Baseball Hall of Fame requesting the scorecard to document this historical occurrence. The Red Sox, who are making a series of roster changes, are looking to close the gap in the wild-card race after being swept by the Arizona Diamondbacks. Meanwhile, the Blue Jays will have right-handers José Berríos and Ryan Burr pitching in the doubleheader. Boston reinstated pitcher Justin Slaten and optioned Josh Winckowski to Triple-A Worcester in preparation for the games.
