Thomas Nestico, also known as tjstats, is a person who brings a rather unique combination of skills to the table. He's someone who started out as a civil engineer, which, you know, involves a lot of precise thinking and problem-solving in building things. But, somewhere along the way, he found a real spark, a strong interest in something quite different: working with data and using machines to learn from that data, especially when it comes to sports. He is, to be honest, a proud Canadian, which gives a little bit of background to his story.
It's interesting how someone can move from one field to another, yet still apply the same sort of logical thought processes. Thomas Nestico seems to do just that, taking his engineering background and putting it to good use in the world of sports information. He has a baseball blog, which he calls tjstats, and it is there that he shares a lot of his thinking and discoveries. This is where he talks about his passion for looking at numbers and what they mean for the game. He's very much into figuring out how players perform, using information to get a clearer view.
There is also information about another individual named Thomas Nestico, born on July 13, 1951, making him 73 years old. This Thomas Nestico lives in Burlington, Connecticut, and previously lived in Bristol, Connecticut. He has been known by names like Thomas S. Nestico, Thomas S. Nestica, and Thomas Nestica. It is important to note that the detailed work in sports data analytics and machine learning is associated with the Thomas Nestico who goes by "tjstats." The information provided in "My text" includes both, so it is good to clarify that the focus here is on the person behind the sports data analysis.

What Kind of Work Does Thomas Nestico Do?
So, what exactly does Thomas Nestico get up to with all this data and machine learning? Well, he spends a lot of his time looking at baseball, specifically pitching. He's interested in things like classifying where pitches land in a baseball strike zone, and then trying to guess where pitches might land in minor league games. It is a bit like trying to predict the future based on what has happened before, using a lot of numbers to help make those predictions. He also takes a look at what he calls "under the radar" pitching prospects, which are players who might not be getting a lot of attention but could turn out to be really good.
He has a way of looking at pitchers that goes beyond just watching them throw a ball. He looks at things like how fast a pitcher's fastball is, or how one type of pitch compares to another from the same pitcher. For instance, he noticed that a pitcher named Warren had his changeup and sinker pitches looking very similar, which was a bit of a problem because they didn't act differently enough. This kind of observation, you know, helps people understand why some pitches work better than others, or why a pitcher might be struggling a little bit. It is all about getting down to the specifics of what is happening with each throw.
His work also touches on how different pitches create value in a game. He has a system called "tjstuff+" which figures out the expected run value of a pitch. This is a way of putting a number on how good or bad a pitch was, based on how likely it was to lead to runs being scored. It is a pretty clever way to look at things, giving a concrete way to talk about the impact of each throw. He has even made the code for his pitching summaries public, which is, honestly, a generous thing to do, allowing others to see how he does his work and maybe even learn from it. This sharing of information is something he believes helps others get better at understanding these things.
How Does Thomas Nestico Look at Pitching?
When Thomas Nestico considers pitching, he does not just see a ball being thrown. He sees a lot of information contained within that single action. He's quite keen on the idea of pitch zones, which are like specific areas where a pitcher aims to throw the ball. He looks at how pitchers manage to hit these zones in the major leagues and then tries to figure out how that might translate to players coming up through the minor leagues. It's a bit like mapping out a strategy for where the ball should go, and then seeing how well pitchers actually follow that plan.
He also pays close attention to the characteristics of different pitches. For example, he has looked at how a pitcher's fastball speed compares to others. There was a time when a pitcher named Degrom had his fastball averaging a certain speed, and Thomas Nestico pointed out that this was a speed he had not averaged since an earlier successful season. He also noted that this pitcher was having some trouble getting batters to miss his pitches. This kind of detail, you see, helps to explain what might be going on with a pitcher's performance, giving a deeper picture than just looking at the final score.
Then there's the idea of how different pitches from the same person interact. He noticed with a pitcher named Warren that two of his pitches, a changeup and a sinker, were very much alike in how they moved. This sameness was an issue because these pitches were supposed to be different enough to trick batters. When they looked too similar, they lost some of their effectiveness. Thomas Nestico's work, more or less, helps to uncover these kinds of subtle points that can make a big difference in a game, showing how even small variations can have a large impact on how a pitcher performs.
What is Expected Run Value and How Does Thomas Nestico Use It?
Expected Run Value, often called xRV, is a concept that Thomas Nestico uses to put a number on how much a single pitch contributes to or takes away from a team's chances of scoring runs. It's a way of looking at each throw and saying, "Based on what usually happens from this kind of pitch in this situation, how much did it change the likelihood of runs being scored?" So, a pitch that makes it much more likely for a team to score would have a high positive xRV, while a pitch that gets an out and reduces scoring chances would have a negative xRV. It is a pretty sophisticated way to evaluate individual pitches.
Thomas Nestico's "tjstuff+" system calculates this expected run value. This means he has built a way to process a lot of information about pitches – things like their speed, how much they spin, where they cross the plate, and what the situation in the game is – and then use that to figure out the xRV. This is, actually, a very helpful tool for understanding the true worth of each pitch thrown in a game, moving beyond just whether it was a strike or a ball. It gives a deeper sense of a pitcher's effectiveness and a batter's ability to make something happen.
By using xRV, Thomas Nestico can give a more detailed picture of a pitcher's performance than traditional statistics might offer. It helps to identify pitches that are particularly good or bad, even if the immediate outcome wasn't obvious. For example, a pitch that looks like a ball might still be a good pitch if it sets up the next one perfectly. This kind of analysis helps fans and teams get a clearer view of what's working and what's not, allowing for more informed decisions about players and strategies. It is, you know, a way to add more depth to how we think about the game.
Can We Learn From Thomas Nestico's Work?
Yes, absolutely, there is a lot to take away from the kind of work Thomas Nestico puts out. One of the most important things is how he approaches making his code public. He believes that making his code available for others to see is the best way for people to learn and improve their own understanding of data analysis in sports. It's a very open way of sharing knowledge, which is, honestly, quite refreshing. This means that if you are interested in how he gets his results, you can actually go and look at the underlying processes he uses.
This openness also helps to build a community of people who are interested in the same things. When someone shares their methods, it allows others to check the work, ask questions, and even build upon it. It's a bit like a collaborative effort, where everyone can learn from each other's insights. Thomas Nestico's approach shows that there's value in transparency, especially in fields where data and complex calculations are involved. It encourages a deeper look into how conclusions are reached, rather than just accepting them at face value.
Moreover, his work highlights the value of looking at details that might not be immediately obvious. The idea of "under the radar" pitching prospects, for example, tells us that there are hidden gems out there if you know how to look for them. It suggests that traditional ways of evaluating players might miss some important things, and that data analysis can help uncover those overlooked talents. So, his work teaches us to question what we see on the surface and to dig a little deeper for a fuller picture, which is, quite frankly, a good lesson for many areas of life, not just baseball.

Spring Scouting with Thomas Nestico
Thomas Nestico has a series called "Spring Scouting," which is a pretty cool idea for anyone who follows baseball prospects. Spring training is a time when new players and those coming up through the ranks get a chance to show what they can do before the regular season begins. This series, in a way, aims to give people a heads-up on what to look for during this important period. It is about spotting talent and potential when it is still early, which can be very exciting for fans and teams alike.
The idea behind "Spring Scouting" is to provide insights into players who might be making a name for themselves, or who are showing new aspects of their game. It is not just about the big names everyone already knows. It is about those players who might be quietly putting together impressive performances, or who have made adjustments that could lead to a breakthrough season.
