Where did their Spin go?

Usually when a pitcher adds more spin to his fastball you see a relatively similar increase in velocity; however, these 5 pitchers go against this pattern drastically.  I looked at 5 pitchers’ fastballs who have lost 100 or more RPM this year compared to their 2020 data, while also showing an increase in velocity.  These...

Coors Field’s Impact on Pitch Movement

Coors Field has long been synonymous with offensive slugfests which give pitchers nightmares. In addition to this, we know that the higher altitude in Denver is what affects the baseballs' trajectory as they are both thrown and hit. Often the "thin air" is brought up as what allows the baseballs to travel further in Coors... Continue Reading →

Moving Forward with “Win Score”

If you are unfamiliar with the term "Win Score" please check out the: Introducing "Win Score" article. The equation for Win Score as stated in that article is: Win Score = [(League average runs-(ERA+FIP)/2)*5 + .75(innings) + .5(strikeouts)]/Games Pitched. The point of Win Score is to replace the current "win" statistic as it is outdated... Continue Reading →

Introducing “Win Score”

Pitchers in Group 1 have a record of 0-10 with a 2.69 (ERA+FIP/2) vs. pitchers in Group 2, with a record of 7-0 with a 5.08 (ERA+FIP/2)... Historically, the “Win” has been a steady metric that has been simple to understand and commonly used to judge how good a pitcher was.  Over time we have... Continue Reading →

What Actually Contributes to BABIP?

In the field of statistics, we use the the law of large numbers to explain that as the sample size of something increases, the average of that sample will fall closer to the mean of the population as a whole. The proof of this law has existed since the publishing of the book Ars Conjectandi... Continue Reading →

Is Stealing Signs Necessary?

While baseball has always been a game of numbers, the increase in large datasets and the availability of these datasets over recent years has greatly facilitated the ability of both public analysts and teams to draw conclusions and insights into the game that they previously would not have been able to.   As the data has...

A Discussion of Spin Efficiency

We have long been aware of the fact that baseballs spin when traveling through the air and that Major League Pitchers are able to generate quite a lot of spin when they release their pitches (average spin rate on Major League pitches was around 2270 RPM’s last year). It has been common knowledge for a... Continue Reading →
