In 2012, the Braves began their 138th season after an upsetting end to the 2011 season. On March 22, the Braves announced that third baseman Chipper Jones would retire following the 2012 season after 19 Major League seasons with the team. The Braves also lost many key players through trades or free agency, including pitcher Derek Lowe, shortstop Alex González, and outfielder Nate McLouth. To compensate for this, the team went on to receive many key players such as outfielder Michael Bourn, along with shortstops Tyler Pastornicky and Andrelton Simmons. To fill the void of a quality starting pitcher left by Lowe (as well as a mid-season injury to Brandon Beachy), manager Fredi González elected relief pitcher Kris Medlen to the starting pitching rotation. The Braves went on to win every game Medlen started, setting the MLB record for most consecutive wins when a single pitcher starts (total of 23). Atlanta stayed close to the Washington Nationals in the race to win the National League East title. They also stayed on top of the National League Wild Card race. Washington ended up winning their first division title in franchise history, but the Braves remained in first place of the NL wild-card race. Keeping with a new MLB rule for the 2012 season, the top two wild card teams in each league must play each other in a playoff game before entering into the Division Series.
