Major League Baseball returns to London this weekend for the second annual London Series. Last year they sent the St. Louis Cardinals and Chicago Cubs for England's first official taste of the MLB regular season and this year they'll send another rivalry.
While it was a longtime joke that the NFL sent unpopular franchises (particularly the Jacksonville Jaguars) to London for games, MLB has such a long regular season they can afford to send high-profile rivals to other countries for a few games whenever they feel like it. Even if they aren't taking full advantage of current lineups for advertising purposes.
The Philadelphia Phillies and New York Mets will play in London this year. The Phillies are 44-19 and have the best record in the National League, while the Mets are 27-35 and sit in third place in the NL East.
