A London series between the Boston Red Sox and New York Yankees is reportedly closer to being finalized, with a 2019 regular-season series in the works.

Major League Baseball has had regular-season games in London on its radar for some time, and it has seemed possible that the Red Sox-Yankees rivalry could be used as a showcase for the league. While there have been no official announcements, discussions of the teams meeting for a two-game series at London Stadium in June 2019 are reportedly making progress.

According to Bloomberg, an agreement for the London series is closer to being finalized, but some details still need to be resolved:

The series would be played at London Stadium, the main facility for the 2012 Olympics, said the people, who asked not to be named because they weren’t authorized to discuss the matter publicly. Details still need to be ironed out.

Officials for Major League Baseball and the teams didn’t immediately respond to emails seeking comment.

MLB games set for 2018-2021 in Asia, London, and Mexico were previously announced as part of the newest five-year collective bargaining agreement, signifying the sport’s intent to make a more aggressive worldwide push. There are a handful of off-site MLB regular-season games taking place during the 2018 season. The Minnesota Twins and Cleveland Indians will play an April series at San Juan’s Hiram Bithorn Stadium, while the San Diego Padres and Los Angeles Dodgers are already scheduled to play a Monterrey series in May.
