Liz appears to be a Philadelphia Phillies fan. In "Reaganing", it is mentioned that at nine years old, she sported a Pete Rose inspired haircut and had posters of Mike Schmidt and Tug McGraw in her bedroom. These three players were active with the Phillies during this period. It is also noted that she uses a "Phillies Sport Wallet" in "It's Never Too Late For Now". In the season 6 finale "What Will Happen to the Gang Next Year?" Liz tells Jack that in payment for officiating at his and Avery's renewal of vows, "I get your Yankees tickets on A-Rod bobble head day. And I'm going to throw that thing in front of a train. Go Phillies!"
