His ERA was over 2 full runs higher in 1998 before the trade compared to 1997 but, sure, his stats were right in line.

This is the type of nonsense I'm talking about. The fact that he posted an ERA of 2 runs higher than he did the year before in Seattle at the trade deadline literally means absolutely nothing. It tells you nothing about how well he was pitching without also looking at his other stats like FIP, BABIP, K/9 and BB/9. The data clearly shows that he simply got unlucky over the course of the first 2/3s of the season but was still every bit as dominant with the factors that were within his control.

Beware of Stats.

1. that do not always mean anything
2. Different people value different stats differently
3. Some people use the Same Stats and read it differently to make their points

I thought a pitcher's BABIP could be indicative of his ability to induce weak contact and therefore having a higher one than typical could indicate he was not pitching as well as before and not just random bad luck.

Anyhow I guess his bad luck just disappeared the day he was sent to Houston and his BIP then dropped by over .3 for the rest of the season. Just regression to the mean, inconsequential.

Yeah Peter, I vaguely seem to remember someone on here posting about how they used that same statistic to declare that Spahn was just lucky and not so great a pitcher. Good thing his luck didn't last for more than 363 wins or 20 or so successful winning seasons. Otherwise, people might actually begin to question the infallibility of such a statistical measure and the thoroughly conclusive answer that can be gleaned and ultimately drawn from it in regards to something as readily and objectively measurable as the level of Spahn's luck. But of course, we all know that a loss of faith in statistical infallibility would never happen, especially when such a conclusive and non-arguable determination of Spahn's luck is drawn from such totally unbiased and all-inclusive statistical and intangible data by qualified data scientists in their unrivaled capacity and knowledge, the results of which they so unselfishly bestow upon and honor us with. For without them, we, the unknowing minions, would truly be in the dark. But fortunately for us, we have our beloved statisticians and data scientists to instead smile down upon us with their sage and benevolent wisdom, and lead us unto the light! Amen.

(Shoot! Did I just cross a line and post something religious? If so, my apologies, no offense meant to anyone............well, almost!

Yes, it did. This happens all the time. He even got lucky in Houston. His HR% was half of what it normally is for him during those 10 starts. Anything can happen in 11 starts. It's just way too small of a sample size. Hell, nearly anything can happen even over the course of a full season too, let alone 11 games.

A pitcher's BABIP is almost entirely outside of his control. There are some who suggest that they may be able to exercise some minuscule amount of control over it, to the tune of a few points, but that's not an easy sell even at that. Either way, large fluctuations above and below the league average BABIP is indicative of a pitcher having gotten either lucky or unlucky that season. Just go look up your favorite 10 pitchers and look at their best and worst seasons with respect to their ERAs and WHIPs. You'll usually find that those were usually just seasons where every bounce or wind gust went their way (or failed to when their numbers were "bad"). Especially when there is a discrepancy between their ERA and their FIP.

If I want to know how well a pitcher performed, I look at the stats that are within their control.

Your logic would mean there's no such thing as a great pitcher who pitches to contact, or who isn't a dominant strikeout pitcher, because once a batter puts a ball in play it's all just dumb luck. That just does not square with experience. Did you ever watch Greg Maddux pitch?

Put another way, putting a ball in play on a pitch that was a hanging curve or a fastball with no movement down the middle is just not the same as doing so on a wicked slider two inches off the plate. A great pitcher can throw more pitches that are difficult to make solid contact with and thus your chances of getting a hit off him on a ball you put into play is not just random or some stat that will eventually hit the mean.

One more famous one that didn’t make the first page cut:

“Statistics are like a bikini. What they reveal is suggestive, but what they conceal is vital”

Oooooo, I like that one.

Trying to keep it in a baseball vein, here's one I think would have been a classic Yogiism:

Statistics can always tell you everything you want to know.........about half the time!

As this thread shows all too well, raw data may be objective, but how one presents and interprets it is anything but.

63% of all statistics are fake.
