But when the 1958 season began, McDaniel became inexplicably wild. He appeared in only two games for the Cardinals, and in two innings issued five
walks, gave up three hits and three
earned runs, and was dispatched to the Class B
Carolina League to try to regain his effectiveness. Although McDaniel rebounded somewhat in 1959, in Class D, then the minors' lowest classification, he never conquered his control problems. As events turned out, his final appearance in Major League Baseball occurred on May 11, 1958. "He lost his coordination and his mechanics", Lindy McDaniel told author
Pat Jordan, himself a former professional baseball pitcher, in 2001. "There was no real explanation. Some people thought it was psychological. But who knew about those things then? They sent Von down to the minors, but he couldn't get anyone out. He kept sinking further and further until he couldn't pitch anymore." ==Conversion to third baseman==
