Slugger and Betty Stetson dance during her 100th birthday party in Windham. The Red Sox sent a letter thanking her for her support. The Red Sox won three World Series titles during her lifetime; the first one the 1918 series when Babe Ruth led the team to the championship.

Betty smiles while opening gifts from the Boston Red Sox organization at her party. Her favorites included a bobble-head of Manny Ramirez, her favorite player, and a little piece of Fenway Park sand.
