The number the box score doesn't want you to see. NUT measures real player value in wins, built on hitting (wOBA) and pitching (FIP) — the parts of the game you can measure precisely. One number, calculated the same way every time, so a Pirates fan and a Mets fan are arguing about the same data.
How NUT Score works →Baseball stats can be confusing — from basic numbers like batting average (AVG) and earned run average (ERA) to advanced metrics like weighted on-base average (wOBA), fielding independent pitching (FIP), and wins above replacement (WAR). This glossary breaks down every MLB stat in plain English so you can follow the game without a statistics degree.
Baseball Nut uses the NUT Score— a single number that measures how many wins a player adds to their team using only hitting and pitching stats. Whether you're new to sabermetrics or just need a quick refresher, start with any section above.
