St. Louis Cardinals Hall of Famer Lou Brock has died ... this according to the St. Louis-Post Dispatch.
Reporter Rick Hummel says Brock passed away Sunday afternoon, adding he was battling multiple medical conditions near the end of his life. The exact circumstances of his death remain unclear.
Brock was a living legend in Missouri, as he's best known as one of the greatest Cardinals players ever who helped lead the franchise to a World Series title in 1964 ... the same year he was traded to the team from the Chicago Cubs.
