The Diamondbacks and Padres are in discussions with MLB about playing a regular season series in Mexico City next year, report Dennis Lin and Ken Rosenthal of The Athletic. The league has yet to make that event official.
MLB and the Players Association agreed to the establishment of the “World Tour” series to promote international play in the 2022 collective bargaining agreement. The CBA provides for a possible Mexico City event in May 2026. It also includes the possibility for a London series in June and one in San Juan in September, but MLB has not proceeded with every World Tour series contemplated in the bargaining agreement. The CBA permitted 2025 events in Mexico City, Paris and San Juan — none of which will happen for economic reasons.
Arizona and San Diego were scheduled for a two-game series in Mexico City on April 18-19, 2020. Those games were canceled for obvious reasons. MLB played its first regular season games in the city three years later. The Padres and Giants met for two games on April 29-30, 2023. The Rockies and Astros played there on April 27-28 last season.
There will not be any regular season contests in Mexico this year, though the Red Sox played a pair of Spring Training games against a Mexican League team in Monterrey. The only regular season action outside the U.S. and Canada this season was the season-opening Tokyo Series between the Dodgers and Cubs.
