The Cardinals' Lou Brock throws out a ceremonial first pitch while wearing a "Brockabrella" on July 2, 2010 at Busch Stadium. "Brockabrella" replicas were given to fans in a promotion that day. Brock popularized the umbrella hats in the 1970s. (Post-Dispatch file photo by Chris Lee)
Lou Brock's story often starts with The Trade, a swap made in 1964 that left Cubs fans cheering the addition of proven pitcher Ernie Broglio while Cardinals players questioned the price paid for an unproven outfielder who was about to spend the next decade and a half lighting the club's fuse.
