Great question EH!
There is something about the sport that brings the supersticious side out of people. The Red Sox trade Babe Ruth and it feels like a curse hangs over the franchise for better parts of the next century. I think of things like Bill Buckner and the fan in Chicago who robbed Moises Alou of an out. In NY, the luck seems to go their way - when a fan robs the Orioles of an out not only do the Orioles not get an out, the fan turns interference into a homerun
Jinx type things even seem to happen to umpires sometimes like Don Denkingers' famous blown call at first base to allow KC to win their only World Series.
I think of might-have-beens like Tony Conigliaro and Herb Score who saw their careers end due to freakish accidents.
Often times the best team does not win. The 1954 Indians set a record for wins in a regular season yet saw a young, brilliant Willie Mays' catch of a Vic Wertz shot turn a series underdog into a four game sweep. The Indians are still looking for their first World Series since 1948. In 1997, they were three outs away from that elusive win but they lost it to an upstart expansion franchise. In 2007, they had Boston down 3-1 and seemed destined for the world series with CC Sabathis and a hot Fausto Caromona on the mound. It was not to be and now their manager has been fired after being named manager of the year in 2007.
In my own personal circumstances, many times I expected things to go well and they turned out poorly. Conversely, it seems like remaining humble can sometimes ward off the evil spirits the game seems to conjur up. The funny part is, I could go on and on and on about things as I am sure each one of you can as well. The game has a way of turning reasonable people supersticious
