Boston Red Sox v New York Yankees: A global rivalry
As sporting rivalries go, few have as much history as the Yankees vs the Red Sox.
New York and Boston have played 2,196 times. The Yankees have the edge in the head-to-head record, winning 1,191 games to the Red Sox's 991 with 14 ties. The Yankees also boast a 12-11 advantage in postseason match-ups.
From curses to epic comebacks, the 100-year rivalry has produced its fair share of drama and the latest chapter will unfold in Stratford, East London.
Boston dominated baseball in the early years of American League Baseball, winning all five of the World Series that they competed in between 1903 and 1918.
Then, in 1919, a deal was struck that would come to define the rivalry, altering the course of major league baseball in the process.
Red Sox owner Harry Frazee decided to sell star player Babe Ruth to the Yankees starting an era that became known as the so-called 'Curse of Bambino' in which Boston failed to win a championship for the next 86 years.
The ensuing years saw the Red Sox become the perennial hard-luck merchants, while the Yankees became the most successful baseball team of the 20th century, winning 25 championships between 1923 and 1999.
It wasn't until the turn of the millennium that Boston managed to restore parity in what had become a one-sided rivalry.
In 2004, the Red Sox overturned a 0-3 deficit to beat the Yankees on the way to their first championship since 1918.
After finishing the regular season with a new franchise record of 108 wins, Boston entered the 2018 playoffs as favourites to win the championship.
Meeting the Yankees in the best-of-five playoff series, the Red Sox needed just 4 games to beat their rivals en-route to defeating the Los Angeles Dodgers for the 2018 World Series Championship
Boston have won two more World Series since then while New York have lagged behind, winning twice in 2000 and 2009 to take their all-time haul to 27 titles.
All that means fans at the London Stadium are in for a mouth-watering encounter when the two teams square-off on Saturday, June 29.
Speaking at the announcement of the 2019 London Series, former Yankee Alex Rodriguez, who won the World Series with New York in 2009, insisted UK baseball fans are in for a treat.
"We are coming with our best two teams, with great players and great history. These teams are both championship-calibre teams.
"It’s the oldest rivalry. It’s a love-hate relationship: they both have so much respect for each other, but we love to beat up on the Red Sox, and they love to be beat up on the Yankees.
"It goes back 119 years, having played each other over 2,000 times. It’s like Cambridge and Oxford in the Boat Race."
London mayor Sadiq Khan hopes the game will help baseball become a part of the city's sporting landscape for years to come.
"Since I became Mayor, I have been determined to bring baseball to our city and I am really pleased we have been able to reach what is an historic agreement," he said.
“I’m committed - as is MLB - to ensure baseball has a long-term future over many years in London.”
