On the series of April 20–22, 2012, the Red Sox celebrated the 100th anniversary of Fenway Park against the Yankees, who they played to open up the park. Both teams wore their 1912 uniforms on April 20, which the Yankees won 6-2. The Yankees came back from down, 9–0, to win, 15–9, the next day, the largest deficit they have ever overcome. They won the season series 13–5, their best record against the Red Sox since 2001, when they also went 13–5 against them, and swept the final three-game series of the season at Yankee Stadium to clinch the AL East while the Red Sox finished last in the division for the first time since 1992 with their worst record since 1965. Valentine was fired soon after. Later in 2012, the Yankees acquired 2004 ALCS Game 7 winner Derek Lowe. He was the latest member of the 2004 team to later play for the Yankees. After the 2012 season, Kevin Youkilis, who the Red Sox traded to the Chicago White Sox earlier in the season, signed with the Yankees as a free agent. He had previously clashed with Joba Chamberlain when he was with Boston.
