Most people who love baseball have their superstitions. Hunter Pence gives fiery speeches when the Giants are in win-or-go-home situations, my grandmother wore the same shirt for every Giants game she watched on TV, and there are always those fans who need garlic fries or a crab sandwich when at Oracle Park.
Why do we do it? Because past experience has proven to result, at least a majority of the time, in a win for our team.
But there are times when superstitions and coincidences fall in line too many times to where they have to be accepted as potentially mathematically likely or just flat-out true.
