The Red Sox returned to postseason play in 2009, but were swept in the ALDS by the Los Angeles Angels. In 2010 they placed third in the division and failed to make the playoffs. In 2011 the Red Sox collapsed, becoming the first team in MLB history to blow a 9-game lead in the division heading into September, as they went 7–20 in the final month and failed again to make the playoffs. In December 2011, Bobby Valentine was hired as a new manager. The 2012 season marked the centennial of Fenway Park, and on April 20, past and present Red Sox players and coaches assembled to celebrate the park's anniversary. However, the collapse that they endured in September 2011 carried over into the season. The Red Sox struggled throughout the season due to injuries, inconsistent play, and off-field news. They finished 69–93 for their first losing season since 1997, and their worst season since 1965.
