No-hit performances by pitchers are a bit like throwing a bulls-eye in a game of darts. The difference between a skilled dart-thrower and a non-skilled dart-thrower is great; it is unarguably a skill that is improved by the muscle memory gained via practice. Much like anything in life, skill at darts progresses along a curve; making the same effort to improve will provide diminishing returns as you move up in skill. One cannot practice enough to be able to throw a dart into the bulls-eye every time; it is conceivably possible to comprehend, but the amount of practice that would seemingly be required is prohibitive. This same effect can be seen in most any field where skill plays in; an average Joe has a miniscule chance of beating a master dart-thrower in a standard game of darts, but relative to the gap between their skill levels they have a much closer-together chance of throwing three bulls-eyes in a row. There’s an old expression about how you have to be good to get the chance to be lucky, and baseball offers more glimpses at the elite getting lucky than possibly any other modern entertainment.
