Tommy Lasorda Baseball is a sports game developed by Sega R&D 2 and published by Sega for the Genesis.  The game was initially released in Japan for the Mega Drive under the title Super League and was modified for release in North America.

The game was one of six North American launch titles for the Sega Genesis.  Sega of America was looking to capitalize on licensed titles to make their new console appeal to the North American market.  At the time Tommy Lasorda was the manager of the Los Angeles Dodgers and was a very well known and respected manager in Major League Baseball, gaining his personal endorsement for the launch title gave the game marketing appeal.

Although the game was not licensed by Major League Baseball it did include all of the major cities which had MLB teams however could not use the team’s name.  The North American version of the game included four divisions with a total of 26 teams that were inspired by their MLB real life counterparts while the Japanese version had two divisions with a total of 12 teams inspired by Nippon Professional Baseball.  Due to not acquiring a license from the MLB the entire roster of players was fictional and not based on any particular players of the era.

When the game debuted in Europe in 1990 after the release of the Mega Drive in Europe the game was also released as Super League opposed to securing Tommy Lasorda endorsement.  Super League was also released as an arcade game for the Mega-Tech System, which was based on the Mega Drive home console.  The cabinet was designed similar to Nintendo’s PlayChoice-10 where players could choose from a selection of games that were inserted in the cabinet’s printed circuit board (PCB).
