Trafalgar Square was transformed to host a free baseball festival from Friday to Sunday, with thousands attending, and schoolchildren from around the UK visited London Stadium over the weekend, for workout day on Friday as well as the games.
Pupils from Ranelagh Primary School were part of proceedings throughout both games, with MLB having announced it will donate $25,000 (£19,700) to build a permanent baseball diamond for the school, which is less than two miles from London Stadium, and the Stratford community.
MLB has also launched a legacy programme to boost amateur and junior participation in baseball and softball.
Last week, events were staged in Sheffield and Cardiff, and the programme hopes to reach 10,000 primary schoolchildren this year.
A development tournament was also staged at Farnham Park in Slough, home of the UK's only purpose-built baseball and softball facility, with the best 90 prospects from around Europe playing in front of MLB scouts.
"We're at the start of a process here," said Ladkin. "We tried to start it in 2019 and unfortunately got held up in our tracks.
"We're in a really good position now to keep that momentum going. It's going to be interesting to see how that grows, especially knowing that the games are coming back in 2024 and 2026."
