What is a good ISO in MLB?

It varies by year, but well above league average signals real extra-base thump. Compare within the same season.

Is ISO better than home runs?

ISO includes doubles and triples, so it captures a broader power picture than home runs alone.

Isolated Power (ISO) Explained for MLB Hitters

ISO answers a narrow question: when a hitter gets a hit, how much extra-base damage comes with it?

In the notes

Slugging minus average

Isolated power is slugging percentage minus batting average. It removes singles from the power conversation so you can see pure extra-base ability more clearly.

A high average with low ISO is a contact profile. A modest average with high ISO is a damage profile. Both can be valuable; they are not the same job.

Use ISO with playing time

A dazzling ISO in 80 plate appearances is a spark. A strong ISO across a qualified season is a trait. Confirm on Ballrecord player pages before rewriting scouting labels.
