The big number is his career NUT, his total production against league average, with its letter grade. This season's NUT sits just below it, followed by 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.
Tyler Duffey is a free agent pitcher. His career NUT is +0.8, #1,524 of 7,125 pitchers since 1876, and his best season by NUT was 2019 (+0.9). NUT is one number for production against league average: 0.0 is average, and every season is graded against its own league.
Career: 30-27, 4.57 ERA, 479 K in 486.0 IP.
