The Philadelphia Phillies' 2009 season was the 127th season in the history of the franchise. The team, managed by Charlie Manuel, began their sixth season at Citizens Bank Park and defense of their 2008 World Series championship on April 5. After collecting a third straight Eastern Division championship, the Phillies won their second consecutive National League pennant for the first time in franchise history; they were defeated by the New York Yankees in the 2009 World Series.
The Phillies posted a second consecutive winning April to open the season with an 11–9 record, but the month was marred by the death of "legendary" broadcaster Harry Kalas. After opening the month of May against the rival New York Mets, the Phillies met President Barack Obama to celebrate their World Series victory the previous season, and had two rookie pitchers win consecutive starts for the first time since 2007. Starting pitcher Jamie Moyer earned his 250th career win during the month, while first baseman Ryan Howard and outfielder Raúl Ibá?ez became the first Phillies teammates to hit 10 home runs in the same month. Echoing their strong run in the middle of the 2008 season, the Phillies compiled a 16–4 record in late May and early June, which was countered by weakness during interleague play in late June.
