There have been several amazing throws in the modern era, some very well known, some not so well known.
For instance, many people are aware of, and talk about the famous Willie Mays catch of Vic Wertz's smash in the 54 World Series, what alot of people don't know is that the throw that follwed that catch, from the deepest part of the Polo Grounds, was tremendous, and held up a runner that might have otherwise scored.
If you remember the baserunners in the Bo Jackson or Larry Walker situations, please chime in.
