How to read this player page

The big number is this season's NUT, his total production against league average, with its letter grade. Below that are his season and career lines, recent form over 7, 14 and 30 days, game logs, and percentile ranks against every qualified player. NUT is built on the advanced hitting and pitching stats analysts trust, with defense left out, so the number reflects what the player controls.
