The couple officially made an appearance at the Queen Elizabeth Olympic Park to promote the Invictus Games Foundation, Prince Harry’s sports tournament for wounded veterans which is the charity partner for the weekend baseball series in London.
It is the first Major League Baseball (MLB) game played in Europe, and will be watched by a large audience of eager baseball fans back in the US.
Former Invictus competitors from both the USA and UK took part to make the ceremonial first pitch thrown on the ball park.
“The support from these groundbreaking games will significantly enhance the Foundation’s ability to provide recovery opportunities for international wounded, injured, or sick serving or veteran armed forces personnel,” Invictus chief executive Dominic Reid said.
The royal’s baseball outing comes just over nine years after Prince Harry threw the first pitch for hosts New York Mets against the Minnesota Twins on Britain’s Armed Forces Day.
Organisers of yesterday’s game said all 120,000 tickets sold out in 45 minutes.
The first regular MLB games to be played in Europe are expected to open up previously untapped markets for the organisation, which has already staged international events in Mexico, Japan, Australia and Puerto Rico.
