Terrible Months in Good Seasons
Even good hitters go through a cold streaks at some point. If they want to avoid fan panic, though, they need to make sure and save those week or month-long slumps for later in the season. When slumps happen at the beginning of the season, they sandbag the player’s line, and it takes a while for even a good hitter’s line to return to “normal.” Most FanGraphs readers are familiar with the notion of small sample, and thus are, at least on an intellectual level, hopefully immunized against overreaction to early season struggles of good players.
Nonetheless, at this time of the year it is often good to have some existential reassurance. Intellectually, we know that just because a cold streak happens over the first two weeks or month of a season it is not any different than happening in the middle of the year. Slumps at the beginning of the year simply stand out more because they are the whole of the player’s line. One terrible month (and we are not even at the one month point in this season) does not doom a season. Rather than repeat the same old stuff about regression and sample size, this post will offer to anecdotal help. Here are five seasons from hitters, each of which contain (at least) one terrible month at some point, but each of which turned out to be excellent overall.
