Can someone explain to me why baseball keeps separate stats for postseason baseball? I know that when I am watching a playoff game on tv, the batting numbers (average, rbi, etc) are all new. I think that this is odd. The sample size is so small, it is almost a worthless stat. For example a player is batting .300 all year, and then when it comes to postseason, it may say he is batting way worse than his true numbers for the whole season are. Just seems odd to me.
