Great stat:
"Philadelphia's hitters are getting old all at once. In 2007, when this batch of Phillies first made the playoffs, the average age3 of the offense was 28.8 years old. Three years later, the average age of the Phillies' offense was … exactly three years older. At 31.8 years old, the 2010 Phillies had one of the 10 oldest lineups in NL history."
