Baseball scouting is a fascinating mix of old-school intuition and modern data.
Scouts rely on their eyes, experience, and gut feelings, while teams increasingly use numbers, statistics, and predictive models.
This combination makes scouting in baseball both an art and a science. In this article, we will explore how these two sides work together, why both are needed, and how they shape modern baseball.
The Art of Scouting: What Scouts See with Their Eyes
Scouting in baseball existed long before computers, radar guns, or advanced statistics.
For decades, scouts traveled across the country to watch high school games, Little League, and summer tournaments. Their job was to spot talent, project how a player might develop, and write reports. This requires a lot of “feel,” and that is where the art of scouting comes in.
Intuition, Instincts, and Human Judgment
Scouts use judgment to evaluate many traits that cannot be measured with numbers. They assess a player’s character, mental toughness, and how he performs under pressure. Can he handle failure? Is he a leader? These qualities are hard to quantify but are critical for success.
Scouts also evaluate physical tools on the field, such as hitting, running, throwing, and fielding. These are often graded on a 20–80 scale, where 50 is average. The grading combines what scouts see in games with measurable data, but interpretation relies on experience.
For hitters, scouts look at swing mechanics, two-strike performance, and the strength and control of contact. On defense, they assess footwork, glove positioning, body control, and reactions to unpredictable plays. These evaluations require pattern recognition and intuition, making them more of an art than a science.
The Five Tools Concept
A core part of the scout’s evaluation is the “five tools,” which represent the main athletic skills:
- Hitting for average
- Hitting for power
- Running speed
- Fielding
- Throwing arm strength
Scouts grade each tool based on both current ability and projected future performance. For example, a teenage hitter might not hit many home runs yet, but a scout might see raw power in his swing that suggests potential later. Running is also evaluated in game situations, including base running instincts and defensive positioning, not just timed sprints.
The Science of Scouting: Data, Models, and Metrics
While scouting has a long tradition of art, the scientific side has grown dramatically. Baseball has always involved numbers, but modern analytics, tracking technology, and predictive models have changed how teams evaluate players.
Advanced Metrics and Sabermetrics
Sabermetrics involves using data and math to understand baseball performance. Teams use projection systems like PECOTA to forecast a player’s future performance. PECOTA compares a player to historical players with similar traits and estimates probabilities for outcomes like hitting growth, improvement, or decline. These projections include a range of possible performances rather than a single number.
Other specialized metrics include QOP (Quality of Pitch), which evaluates a pitch based on speed, movement, and location, producing a single quality score. Catcher performance is also measured using pitch framing, which estimates how well a catcher can make borderline pitches look like strikes.
Fielding can be analyzed with models that track how players move to field balls, providing objective comparisons across the league.
Blending Data with Observation
Modern teams rarely rely solely on data. The most successful MLB organizations use a hybrid approach. Scouts continue to travel to games, watch players, and fill out tools evaluations for things like arm strength, running speed, and bat mechanics.
At the same time, data teams provide detailed analytics, including spray charts, exit velocity, pitch tracking, and spatial fielding data. Combining human observation with statistical evidence gives teams a complete picture of a player’s skills and potential.
Why Both Art and Science Are Still Important
Data has limitations. Advanced statistics are based on past performance and cannot fully predict the future.
Players grow, improve, or face setbacks. Additionally, character, work ethic, and mental toughness are difficult to measure quantitatively. Scouts’ intuition helps identify strengths and weaknesses that numbers might miss.
Human judgment remains essential because scouts can provide context. A young player may have physical tools but still need coaching or mental development.
Scouts can project how a player’s swing, speed, or strength might evolve over time. When teams draft or sign players, they rely on both statistical evidence and human evaluation to make the best decision.
Frequently Asked Questions
Q: What is the 20–80 scale in scouting?
A: The 20–80 scale is used to grade player skills, where 50 is considered average. Lower numbers indicate below-average ability, and higher numbers indicate above-average ability. Scouts use this scale to evaluate both current skill and future potential.
Q: What are the “five tools” scouts evaluate?
A: The five tools are hitting for average, hitting for power, running speed, fielding, and throwing arm strength. These cover the key athletic skills scouts assess.
Q: What is sabermetrics?
A: Sabermetrics uses data, statistics, and mathematical models to analyze and understand baseball performance. It helps teams make smarter decisions based on evidence.
Q: What is PECOTA?
A: PECOTA is a forecasting system that projects a player’s potential using historical comparisons and probabilities for future performance, improvement, and decline.
Q: How do scouts grade pitches?
A: Scouts evaluate pitch type, velocity, control, and movement. Advanced metrics like QOP combine speed, location, and movement into a single score to measure pitch quality.
Q: Why do teams still use human scouts when they have so much data?
A: Scouts provide context, judgment, and projections that data alone cannot capture. They evaluate character, future growth, and other intangible traits that are vital to a player’s success.
Conclusion
- Baseball scouting is both an art and a science, combining observation with data.
- Scouts use experience and intuition to evaluate physical skills, mental toughness, and character.
- Modern metrics, tracking technology, and projection systems enhance decision-making but cannot fully replace human judgment.
- Teams that blend traditional scouting with analytics gain a more complete understanding of a player’s potential.
- Scouting is a creative and analytical process, essential for identifying the next generation of baseball talent.
