“We have lost an iconic member of the White Sox family today,” White Sox chairman Jerry Reinsdorf said in a statement. “None of us will ever forget that ninth inning of Game 4 in Houston, all that Bobby did for the 2005 World Series champions and for the entire Sox organization during his time in Chicago. He and his family knew cancer would be his toughest battle, and he will be missed as a husband, father, friend and teammate. He will forever hold a special place in all our hearts.”

A two-time All-Star, Jenks played seven seasons in the majors — six with the White Sox and one with the Boston Red Sox. He emerged as a rookie sensation in 2005, notching four saves with a 2.25 ERA during the postseason, including two series-clinching saves: one in the ALDS against Boston and another in the World Series against Houston.

Jenks recorded 173 career saves and was known for his intimidating presence on the mound and his high-velocity fastball that routinely touched 100 mph.

He is survived by his wife, Eleni, and six children.
