Reading Heston Kjerstad's 2026 Sabermetric Line

This page translates the standard batting line into modern sabermetrics. Instead of just AVG/HR/RBI you'll see wOBA (weighted on-base average — the single best snapshot of offensive value, where .320 is league average and .400+ is elite), wRC+ (park- and league-adjusted runs created, where 100 is average and 130 means 30% better than league), ISO (isolated power — slugging minus batting average, a clean power indicator), BABIP (batting average on balls in play — roughly .300 for an average hitter; sustained deviations often signal real skill change, but short-term swings can be luck), and K% / BB% for plate discipline.

The radar chart below normalizes each metric so that 100 equals league average; anything above the dotted ring means the player is beating the league, and bigger polygons mean broader excellence.
