<P> To start the 2015 edition of the rivalry, the first game at Yankee Stadium on April 10 went into extra innings ended up being one of the longest games ever played--at 6 hours and 49 minutes--going 19 innings, with the Yankees tying the game three times in the bottom of the 9th, 14th, and 16th . The Red Sox won the game, 6 - 5 . Towards the end of the 2016 season in September, the Yankees headed to Fenway Park trailing the first place Red Sox by only four games . The Yankees ended up getting swept and blew late - inning leads in three of the four games, including giving up five runs in the ninth inning of the first game . The sweep has been dubbed "Boston Massacre II" in reference to the 1978 four game sweep of the Red Sox by the Yankees at Fenway . </P> <P> In 2017, the Red Sox won the division by two games, forcing the Yankees into the Wild Card . This marked the first time both the Red Sox and Yankees made the playoffs since 2009 . However, both teams lost in the postseason to the eventual World Series champion Houston Astros . </P> <P> For only third time in the history of the rivalry (the previous two occasions were 1930 and 1992), both teams had new managers to start the 2018 season . The Yankees hired Aaron Boone and the Red Sox hired Alex Cora, both former players of the team who hired them . During an early - season game, a brawl erupted between both benches after Yankees first baseman Tyler Austin charged Red Sox pitcher Joe Kelly for throwing at him twice in response to Austin's slide at second base earlier in the game . It became a trending topic on Twitter and the MLB's Youtube channel video of the incident became one of the most viewed (currently at an estimated 1 million views), and social media commentators saw the brawl as a spark of a reignited rivalry between the two teams, which in turn released more long - standing hatred among their respective fan bases not just in their respective cities and states but also nationwide . By the end of the 2018 regular season, both teams qualified for the postseason and both reached the 100 - win mark . It would be the first time in history that both teams had won at least 100 games in the same season and, along with the Houston Astros, the first time the American League had three 100 game winners . Following the Yankees' victory over the Oakland A's in the AL Wild Card Game, the two faced each other in the 2018 ALDS . This was the fourth postseason meeting for the two teams, and their first meeting in the ALDS . The Red Sox won the series 3 games to 1, taking games 3 & 4 in Yankee Stadium by a combined score of 20 - 4, with all games broadcast on cable channel TBS in the United States, ending up as one of the highest rating MLB postseason series broadcasts yet in its long history . Just like in the earlier April 2018 brawl, it fueled once more the fan hatred between the two teams, becoming a Twitter trending topic . On October 24, 2018 in Boston, during game 2 of the World Series against the Los Angeles Dodgers, in the top of the ninth inning (as the Red Sox was about to win the game 4 - 2), the fans in attendance started chanting "Yankees Suck!" at Fenway Park, they did the chant the night before as the Red Sox were leading in the scorebooks . As the Red Sox won the 2018 World Series in Dodger Stadium, the "Yankees Suck" chants resounded again from the Red Sox fans attending the series winning game in Los Angeles on October 28 the same year, and the victorious Red Sox players sang Frank Sinatra's cover of "New York, New York" in celebration in the Dodger Stadium locker rooms (that song, the one played at Yankees home victories, was the one played in Yankee Stadium when the Red Sox won in the aformentioned 2004 ALCS and in the 2018 ALDS). </P> <P> In May 2018, MLB announced that the Yankees and Red Sox would play a two - game series during the 2019 season at London Stadium, in the first of year of a two - year deal to play regular season games at the venue . The MLB London Series will be the first time that the two sides have played each other in regular season play outside of either New York or Boston, and will also be the first MLB regular season games to be played in Europe . </P>

When was the last time yankees and red sox played in the playoffs
