You think there's gotta be a good story behind this. Is Hendrick secretly protesting the Cards' unis? Is the leisure zip-up under consideration as warm-up gear? Was the brass considering switching the tradition Red Bird unis for something more along the lines of the Astros's eclectic gear?
Who knows, but Hendrick is the only brave soul I've seen rocking that get up.
Have a good one and goodnight Pumpsie Gree, wherever you are!
