Why are s f giants wearing red hats today?

The White Sox will wear red pinstripes and hats for home Sunday games in 2012, replicas of uniforms they sported in the early 1970s when franchise icons Dick Allen, Wilbur Wood and Bill Melton ruled the South Side of Chicago. From 1971-1975, the White Sox hit on a sharp look that combined their iconic "Sox" logo and a red pinstripe color scheme, rarely used at that time in Major League Baseball.
