Jack the Giant Killer

Happy 141st birthday to former #Cubs great Jack "The Giant Killer" Pfiester. He got his nickname because he always seemed to beat the arch-rival Giants. Pitched in 1906-07-08-10 World Series. His 1.86 career ERA is the second best in Cubs history (Mordecai Brown) #everyCubEver pic.twitter.com/C1AK8fgxE8
