When Is a Torpedo Is Not a Torpedo?

When it’s a torpedo bat.

Last week I looked at baseball’s new torpedo bats in a humourous light. But I did want to take a more serious look, because bat evolution has been part of the tale of baseball since its beginning. Back in the day bats featured long lengths and heavier weights. These days, bats are in the mid-30 inch length and mid-30 ounce weight. Current regulations limit bats to 42 inches in length and a maximum diameter of 2.61 inches. 1 (There is some other stuff in there that is not terribly relevant to the torpedo bat.) And that’s it. Nothing about where the widest part of the bat need be nor the overall shape—merely a round, solid piece of wood.

The solid piece of wood is connected to corked bats. At my age I remember seeing the ESPN clips of Sammy Sosa’s corked bat in 2003 and the story of Albert Belle’s bat, stolen from the umpire’s room.

The torpedo bat, however, is not corked, instead it uses increased mass at the bat’s sweet spot, where it generates the greatest exit velocities when the batter hits the pitch. This graphic from ESPN shows how this works.

How a torpedo bat differs from the normal bat

Overall I like the graphic. The use of contrasting red and blue does a good job highlighting, particularly at the end where the normal bat continues with its edges running parallel as a regular cylinder. The torpedo bat changes into a cone with its top sliced off then rounded. I might have exaggerated the vertical dimensions of the bat illustration, but it still works.

Additionally, as I understand the design, it maximises the diameter of the bat to the aforementioned 2.61 inches. I have heard—but not confirmed—most bats do not reach the full diameter. If that is true, perhaps an illustration where the red lines fell below the maximum diameter of the torpedo bat could do a better job differentiating between the two shapes.

I prefer the above illustration to that produced by the Athletic/New York Times, which attempts a similar distinction.

New York Times version of the graphic.

I think ESPN’s overlay better shows the difference and that the Athletic’s wood pattern distracts from the graphic overall. Whereas ESPN uses the solid red vs. blue hatching to distinguish between the two shapes.

Of course that begets the question, why doesn’t every batter use the torpedo bat?

Suffice it to say, some players are better at hitting the ball consistently at the same spot on the bat. If a hitter can repeatedly make contact at a specific spot along the length of the bat, it makes sense to concentrate the mass of the bat at that spot for better hard contact. If, however, a hitter spreads his contact out along the length of the barrel, he probably wants a more evenly distributed mass to help create a better spread of good contact.

Regardless, as I wrote on Friday, the torpedo does not look like a torpedo. If anything, the normal baseball bat looks more like a torpedo than a torpedo bat.

Basketball Finals

So the basketball finals begin tonight with the Cleveland Cavaliers taking on the Golden State Warriors. This is also the part of the post where I fully admit I know almost nothing about basketball. I did, however, catch this so-labelled infographic from ESPN contrasting the two teams.

What I appreciate at this piece is that ESPN labelled it an infographics. And while the data might be at times light, this is more a data-rich experience than most infographics these days. Additionally the design degrades fairly nicely as your browser reduces in size.

The chart formats themselves are not too over-the-top (that seemed like a decent basketball pun when I typed it out) with bars, line, and scatter plots. Player illustrations accent the piece, but do not convey information as data-encoded variables. I quibble with the rounded bar charts for the section on each team’s construction, but the section itself is fascinating.

I might not know most of the metrics’ definitions, but I did not mind reading through the piece.

Go Red Sox.

Baseball’s Pace of Play and ESPN’s Pie in Their Face

Baseball is my sport. I love it. Some of my favourite games are the four-hour long matches between my Red Sox and the scourge of the Earth, the Yankees. Games can take a long time for a number of reasons. But in an increasingly fast-paced world, critics argue that younger generations do not have the patience for even three-hour games. So Major League Baseball this year is actively trying to reduce the time of games through pace-of-play improvements. To do this, they are looking at and collecting more of baseball’s copious amounts of data.

Unfortunately, ESPN in an article about the improvements for this year took the data and did nothing with it.

For the love of god, why?

Above we have survey results. I want to vomit in my mouth. Wait, hold on…sorry about that, I am back now. Some organisations have done some really nice visualisations with baseball data, of which we have a lot because the sport plays 162 games per year. We surely could be looking at more timing data. But, instead we get three-dimensional pie charts from ESPN. The rest of the article is not much better, though their styling of bar charts still leaves things to be desired.
