Here's what fans need to know about buying tickets to the gigs.
The first ever Mitel & MLB Present London Series will be held on 29 and 30 June 2019.
The Boston Red Sox and New York Yankees will play a two-game series as part of the regular season schedule in the UK next summer with the events marking the first MLB games to be played in Europe.
The Boston Red Sox will be the home team for both games at the end of June, when the iconic London Stadium will be transformed into a baseball configuration with a crowd capacity of 57,000.
Hospitality packages are available for both games, offering the opportunity to experience the event in true VIP style.
The Clubhouse Lounge hospitality packages allows guests access to a unique space with free-flowing beer, wine and soft drinks, a range of British and American dishes, and appearances by MLB legends.
