In this week's podcast, I sit down again with Dr. Adam Maloof, Princeton assistant professor of Geosciences and athletics fellow for the baseball team.

This time he’s tackling one of the most overlooked problems in baseball analytics: pitch classification.

If you’ve ever looked at a scouting report and thought, “This guy doesn’t throw seven pitches,” you’re not alone. Dr. Maloof explains why existing pitch tagging data from popular systems (TrackMan, Synergy, and MLB’s StatCast) are often inconsistent, inaccurate, and difficult to use for data analysis.

Together, we discuss:

• Why MLB’s pitch classifier is trained on what pitchers call their own pitches (and why that’s a problem for hitters and analysts)
• How Dr. Maloof analyzed nearly 5 million college pitches using a “blank slate” approach inspired by geology
• The “color wheel” analogy: why pitches within a category (fastballs, breaking balls, changeups) exist on a continuous spectrum with no natural boundaries
• How Princeton’s staff uses reclassified data for scouting, pitch design, and pitching machine programming
• Pitch tunneling: what it is, how they measure it, and how they’re teaching it to pitchers
• The role of arm slot, biometrics, and what’s next for this research

In this conversation, Nathan Collier and I sit down to talk about travel ball and high school baseball, and how both play a role in getting players recruited. We dig into what makes each one valuable — like how high school coaches can really vouch for a player's character and how competitive they are, while travel ball helps kids get seen by more coaches. We also talk about how youth baseball is changing, what college coaches are actually looking for, and why picking the right team can make a big difference in how a player grows and develops.

This week, I sit down again with Nathan Collier, Recruiting Service Operations Director here at Patrick Jones Baseball. Together, we discuss the importance of mindset and process orientation in baseball, particularly during the in-season period.

We explore common challenges players face, such as the "I'm Screwed Syndrome," and we talk about the need for players to adopt a process-driven mindset rather than a results-driven one. We also discuss the impact of social media on young athletes, the role of parents, and the significance of having both an approach and a plan at the plate.
