If you're a baseball fan of a certain age (you know who you are), Willie Mays was one of the mythic figures of your youth. Before SportsCenter, you could only catch the occasional glimpse of him in grainy black and white "highlights" or the rare national broadcast with the Giants. Once in a while you could catch him on Home Run Derby, sending moon shots clanking into empty minor league seats. You'd read about him in SPORT magazine and scan the daily box scores in the Globe or the Record American. He was larger than life. His catch in the 1954 World Series against the Indians (photo above) is probably the greatest catch ever. Ever.Let's wish the 'Say Hey Kid' all the best on this, his 80th birthday.
