Bobby Jenks was one of the most memorable closers in Chicago White Sox history, best known for helping the team win the 2005 World Series. Jenks was famous for his powerful fastball, regularly throwing in the upper 90s and occasionally reaching 100+ mph. His final pitch of that championship season resulted in a groundout that clinched the White Sox's first World Series championship since 1917. Jenks died on July 4, 2025, at age 44, after battling Stage 4 stomach cancer. Bobby Jenks has hand signed this Rawlings Official MLB 2005 World Series Logo Baseball.
