The Duke and Duchess of Sussex met with members of the New York Yankees and Boston Red Sox during a baseball game held in London on Saturday.
The teams played in England's London Stadium on Saturday, with the Yankees winning 17-13.
They are scheduled to play another game on Sunday as part of the London Series, which marks the first time that Major League Baseball teams had "regular season games played in Europe," according to an MLB press release.
On Saturday, Prince Harry and the former Meghan Markle met members of the two teams, as shown in pictures shared by the Invictus Games Foundation, a partner of the London Series.
Prince Harry is patron to the foundation, which sponsors sports for wounded, injured or ill armed services personnel and veterans to take part.
It appears the prince and the Duchess of Sussex were gifted a baby's onesie from each of the rival teams for their son Archie, born on May 6.
