In May 2018, MLB announced that the teams would play a two-game series during the 2019 season at London Stadium, in the first of a two-year deal to play regular season games at the venue. The 2019 MLB London Series was the first time that the two sides have played each other in regular season play outside of either New York or Boston, and was also the first MLB regular season games were played in Europe. The Yankees won both games. The Yankees also won four of the five remaining series, pushing the Sox out of contention.
