Overview : From an offensive perspective, I rated & ranked 169 NPB position players using stats for the follow dates 2025 Season Start - 6/16/2025 with a 60 PA Minimum. Players were assessed using a neutralized Run Value system to measure their overall offensive production, broken down into two core components:

• “The Run Tool”— Captures the value generated from non-hit plate appearances (walks, stolen bases, etc.)

• “The Hit Tool”— Measures a player’s offensive impact via hitting.

• “Overall” — A sum of the Run Tool and the Hit Tool, representing overall offensive contribution.

Each player is rated & ranked in these three categories: Run Tool, Hit Tool , and Overall

When I look at players I look at them in terms of production amongst their league and MLB standards. Here is where most player fall in terms of Run Value / PA or Overall Rate using a NPB scale.

That said, I like to compare these players to a MLB standard scale for production to see if they could make the transition. If I were looking to acquire a player from another league with lower competition, then I need this player to be producing at an above average production or better.

I used the MLB Overall Rate scale to color code the spreadsheet to easily identify players measure up against MLB Standards when viewing by Age. To view the spreadsheet by Age click the little calculator looking thing, then select ‘Group by Age’.

Pitching : There is limited data on pitchers in NPB, so I had to use implied probabilities numbers for some XBH values to understand run value, which is why I use the *.

The pitchers are rated the same way in terms of run value but instead of Plate appearance or At Bat, I use Batter Faced.
