Baseball -- The Balls are Not Juiced

I know.  I know.

What I am about to write is heresy.  The easiest explanation for all the home runs in baseball is that the balls are wound tighter, are juiced, jacked, however you want to describe them.  What else explains the wacky number of home runs that future Hall of Famer Justin Verlander has yielded?  What else explains that the Phillies are on pace to shatter the record for home runs yielded in a season?  What else explains, well, all of the home runs?

Except that there are some holes in this argument, and that I think that there might be a better explanation.  I am not a math guy and do not have access to the databases and underlying results that could help prove my case.  So take this post as an outline of an argument -- for a sportswriter to pursue and test to see if it is correct.

First, if you look up all of baseball's numbers, there are other numbers that are compelling, such as how awful bullpens are doing this year.  Second, it isn't as though offense has taken off to the point that the average league OPS or batting averages are way up.  I haven't been able to locate a free site that gives me these numbers, but you would think that if batting numbers overall were way up that topic would be the subject of many broadcasts.  If you go back to the late 1960's, hitting numbers were way down, so much so that MLB lowered the pitcher's mound to take away the pitcher's advantage.  Seemingly, that change worked.  And, yes, now there is talk -- primarily among pitchers and their parents -- about un-juicing the baseballs to reduce the number of home runs to "normal" levels (even though fans like the long ball).  But MLB denies that they are juiced.

So what is going on?

Here is an alternative theory.  The balls are not juiced.  They are the same as they ever were.  It is the deployment of analytics and the changes in batters' behavior that are creating the extra home runs.  

Let's talk about the changes to hitters' tactics.  First, there is significant talk about exit velocity and launch angle.  Take those two approaches together, along with the fact that hitters keep on striking out in record proportion, and you get a partial explanation as to why home runs are way up.  The hitters simply are trying to hit more home runs.  And lots of them.  The numbers guys will tell you that they would prefer strikeouts to balls in play that could end up in double plays.  So, hitters now try to hit the ball up and out as opposed to down and through.  Look at games today; balls are in play an average of about every four minutes.  Players are not trying as much as they used to for singles and doubles; they are trying to hit the long ball.  And they are succeeding.  Presumably, if you place an almost singular emphasis on trying to hit home runs, you will hit more of them, and at the expense of other hits.  To put it differently, if the balls truly were juiced, more of them would be getting through the infield and creating higher batting averages for players.  But that isn't happening.  True, players are trying to hit the ball harder (exit velocity) and further (launch angle), but presumably they would be more successful if you added the juicing of the balls to their approach.  Except the numbers do not seem to bear that out.

Secondly, the pitching.  Pitchers and pitching have not evolved as much as hitting has.  The recent approach to pitching is to have pitchers throw as hard as they can, especially relievers.  That's all well and good, but the analytics are so good that the hitters have been catching up to the overwhelming power of pitchers (who have had an upper hand).  There are a few dynamics going on.  First, starting pitchers are having increasing trouble getting through lineups the second time around and even more so the third time around.  Why?  Because the hitters are getting more and better information and because they get time to adjust to the approach of the pitcher that night.  Second, relievers have very few pitches, making it easier for the hitter to guess what's coming.  Typically, a reliever has a setup pitch and his "out" pitch.  Each is thrown at one speed, hence only two different varieties for the most part.  The analytics guys can help hitters figure out what is coming much more easily than say even five years ago.  Okay, so you'll argue then that averages should be way up, and you'd have a point.  Except one fact remains true -- it is very hard for a human being to hit a baseball.

So what's the solution for pitchers?

Change speeds.  Much more frequently than they currently are doing.  Right now a starting pitcher throws three or four pitches, and some are better than others.  Typically, he throws each of these pitches at one speed.  That means he is throwing only three or four varieties.  That number of pitches makes it easier for the analytics folks to guess the tendencies of the pitchers and teach the hitters what to expect.  The variables are not all that many.  But what if a starting pitcher threw his two- and four-seam fastballs at three different speeds, his change-up at two and his breaking balls at three different speeds, true old-time pitching.  It would be hard for the hitter to know what was coming.  Atop that, this approach could save wear and tear on arms.  Gibson, Koufax, Carlton, Spahn, you name it, all used this approach.  And each could rear back and throw and amazing fastball with a few men on in the seventh to kill a rally.  Increase the number of variables the hitter has to deal with, keep the hitter guessing more than ever.  It just might work.

The same holds true for relievers.  It's easier to tattoo a relief pitcher who throws one out pitch with confidence and a mediocre fastball.  Sure, it was still impossible to hit Mariano Rivera's cutter, but he was an outlier.  Most guys do not have that talent, grit or innate confidence.  The reliever who masters a few pitches and changes speeds just might have more success.

Right now, though, the combination of hitters' focusing on launch angle and exit velocity and an increasing predictability of a pitcher's tendencies because of analytics combine to form the foundation for the additional home run numbers in Major League Baseball.  That is the counterargument to the notion that the balls are juiced.

It's just that contending that the balls are juiced is the easier argument, the one that draws headlines.

Except that it just well could be wrong.
