I looked around on the internet, and found an article stating that if you were to flip a coin 1000 times, an occurrence of 550 heads or tails is like 99.7 percentile chance.

I'm no math guy, but I think that's only a 10% deviation from the mean.
If Mike Trout was regularly hitting between .275 and .225 (in a fully neutral environment), seems like that would be remarkable, according to the math. Not sure it matters how good or bad the competition is, as long as its static.
