Baseball is inherently difficult and a game of failure. When a great player fails 70+% plus time that is proof positive.Well they weren't very good at it then. If they scored 10 runs every game and won in sweeps and blowouts, don't you think the evidence would be a little more supported?
Even when you know what is coming and hit it well it still needs to find some green.
When teams are so even even a slightest of edge can be enough to push you over the top.
