Five minutes before Michael Jordan arrived at 35th and Shields in the winter of 1993, he called White Sox trainer Herm Schneider.
That signaled Schneider to open the garage door by a loading dock where Jordan would drive inside the ballpark for clandestine baseball workouts, which lasted daily about six weeks.
Earlier, that year, Sox chairman Jerry Reinsdorf had pulled Schneider aside at the league meetings in Las Vegas and asked him to get Jordan, the Bulls star who had retired for the first time months earlier, ready for spring training.
