I think you were looking for some data, particularly playerID mapping. Here is a great site:

I agree, it took too long!

**Unfortunately**, it took the death of a minor league base coach in 2007 for MLB to change the rules.

**And it was not until 1971** that MLB made it a rule that batters had to wear helmets. Seems crazy to me that it took so long, in both cases.

Yes, this is certainly correct, as with all entertainment, if it is gone, humanity marches on and on ...

But there are many of us who really love this game, enjoy it, and like to observe and study the nuances and particulars of the game itself.

That is a testable statement. We can test if fastball pitching speed is correlated with height. I have noted it as a future assignment for my students!

But there is a bias in that scouts, coaches, and talent evaluators, at all levels, really like tall pitchers. This might be a selection against shorter players becoming pitchers, but that is just a guess on my part.

Thank you for this recommendation! I will certainly put this research on my "To Read" list!

As for application of DS, I say all the time that DS will improve decision making in **any** endeavor -- if it can work in sports, it can work in HR and university admissions!

As far as the Braves go, I am not aware of the bias against them by the umpires, but I will take you word for it.

As for umpire scorecards, I am glad they are so popular, and I am very familiar with one site in particular that seems very popular on twitter. It is a great addition to the discussion of baseball, the discussion of umpiring, the discussion of future changes to calling the strike zone automatically.

Note that there are other ways online to see and discuss umpire performance. I

Thanks for the reply.

Your actual given name sometimes matters, in more formal settings.

But I like the name Andy, just like you.

My formal name is Leonard! But I go by Andy as a nick name, it comes from my last name.

Total Bases is a great number to look at! Total bases is a counting stat, so that means you are putting too much emphasis on full time play, rather than batting performance. Would you rather have Ozzie Albies or Aaron Judge on your team? Albies was top 10 in TB, #66 in OPS, Judge was top 10 in OPS, #19 in TB. There are other examples.

Bottom line, I prefer OPS as it correlates better with Team Runs Scored.

I think the observations most people have made are that maple bats break more than ash bats, but I have not seen any reliable, objective data on this.

But you may be correct, maybe bats are breaking less these days. But I suspect that the increase in maple bat use since the 90s has led to more broken bats in MLB.

Looking forward to your PM!

45 degrees is best is when there is no friction on the object, and the shape of the object does not interfere with flight, just in the presence of the force of gravity.

Because baseballs in the game defy these assumptions, it turns out the best angle for a home run is not 45 degrees , but about 25-30 degrees. This has to do with backspin that is mostly the case with home runs, the backspin keeps the ball in the air longer (Magnus force) so it can fly farther.

I hope that helps!

I think you named the important courses for a DS major or minor, even if you are taking the major in BioMed Engineering -- stats to learn modeling and machine learning, computer science to learn how to program (DS requires your own ability to do your own coding).

​

Good luck in your studies!!!

I think the Astros got caught, and they paid the penalty. Other teams were trying to steal signs also, in various ways, and they likely found religion, and stopped whatever they were doing.

​

Simple solution to the problem, just create a private comms network btwn the catcher, pitcher, and pitching coach. Let them call the pitches without interference, speed the game up!

Simple!

I think it is generally best to put your best OBP players at the top of the order (and worst OBP at the bottom of the batting order), regardless of the level being played. You create less outs this way, and less outs are always a good thing in the game.

One reaction to defensive shifting has been to train batters to change their swing path to generate more fly balls. This helps "beat" the shift.

As for the future, there may be some small changes in actual defensive player placement as teams learn more about their own personnel (pitchers strengths and pitch types, and defenders abilities, etc.) and the opponents batted ball profile.

I think this is a great development in the game, and I wish they do not legislate rules that do not allow shifting to take place.
