A Scout's Daily Life
NPB scouts observe 200-300 games annually to evaluate draft candidates. Each team employs 10-15 scouts covering assigned regions tracking high school, college, and industrial league players. Evaluation criteria fall into 5 categories: for batters - hitting ability, power, speed, fielding, and arm strength; for pitchers - velocity, breaking balls, command, stamina, and mental toughness. Each category is scored on a 20-80 scale (following MLB scouting conventions) to calculate overall ratings. However, unquantifiable elements represent where scout "eye test" expertise truly matters - practice attitude, teammate relationships, and adversity response influence final draft decisions beyond what data reveals.
Fusing Data and Intuition
Post-2010s scouting evolves toward fusing data analysis with human intuition. SoftBank Hawks operate the largest scouting department among the 12 teams, extending their network not only domestically but to Latin America and Asia. Tracking data objectively measures pitch velocity, spin rate, movement, exit velocity, and launch angle. Yet data cannot evaluate 'potential.' When a high school pitcher throws 140 km/h fastballs, whether he will reach 150 km/h depends on physique, mechanical efficiency, muscle quality, and training attitude - factors poorly captured by data. Veteran scouts hold experiential rules like 'players with efficient body mechanics improve' and 'players with different eyes during practice succeed.' Progressive teams have data and scouting departments debate as equals, integrating both perspectives into draft strategy.
Scouting Successes and Failures
How accurate are scout evaluations? NPB first-round draft picks who become 5-year regulars succeed at approximately 40-50%. Second-round and later picks drop to 20-30%, while developmental draft picks reach the top roster at under 10%. These figures illustrate evaluation difficulty. For high schoolers, predicting how an 18-year-old's physique and skills will develop over 5 years involves extreme uncertainty. College and industrial league players are easier to evaluate as immediate contributors, with hit rates 10-15 percentage points higher than high school picks. Scouts distinguish: "evaluate high schoolers on raw tools, college players on polish."

The Eye Test Coexisting with Technology
Advanced analytics are changing scouting roles. Individual scout judgment once determined everything, but collaboration with data analysis teams is now standard. Some argue 'data makes scouts unnecessary,' but field scouts disagree. Data quantifies past performance; predicting future growth requires human judgment. Scouts also serve the crucial role of building player relationships. Post-draft signing negotiations depend on trust between scouts and players' families. When multiple teams compete for a player, scout interpersonal skills often determine the outcome. Even in the data age, scouting as a profession will persist in evolving forms.
Undrafted Players and Scout Re-evaluation
Players who went undrafted but later succeeded are valuable case studies that challenge scouting methodology. Athletes who develop in industrial leagues or independent leagues and earn high draft picks the following year appear annually. Among scouts, the process of re-evaluating previously passed players is considered essential, demanding flexibility to accurately measure growth without clinging to prior assessments. Reasons for being passed vary: injury history concerns, mental immaturity, or slender builds. These issues may resolve with time, and scouts base decisions on multi-year tracking rather than single-year impressions. Teams with accurate re-evaluation processes tend to find productive players efficiently in middle and lower draft rounds.
Discovering Hidden Gems in Regional Leagues
While attention gravitates toward powerhouse schools in metropolitan areas, finding diamonds in regional high schools and industrial teams showcases scout expertise. Scouts spend hours traveling to games in areas with poor transportation access, evaluating unnoticed players ahead of rival teams. Regional league games feature uneven opponent levels, making accurate talent assessment require experience and skill. Distinguishing players who coast in easy matchups from those who consistently give full effort is critical. Scouts also evaluate regional players' adaptability to environmental change: adjusting to dormitory life away from family and adapting to urban rhythms affect how quickly they become productive. These non-technical observational skills create differentiation among scouts.
Information Warfare Among Scouts
Pre-draft scouting involves information warfare against rival teams. When scouts from multiple organizations gather at games of top prospects, each is careful not to reveal their team's evaluation. Tactics include feigning disinterest to avoid bidding wars, or deliberately making frequent visits to deter other teams. Scouts often have long-standing relationships with each other, and exchanges at observation events involve daily maneuvering between candor and diplomacy. Approaching players' families is also critical: building trust before the draft solidifies a player's willingness to sign. Contact rules through social media have become stricter since the 2020s, making face-to-face relationship-building skills even more important. Scouting depends not only on player evaluation ability but heavily on interpersonal relationship skills.
