HR (Home Runs)
A home run is the most valuable single event a hitter can produce. It scores the batter and everyone on base, ends the inning’s threat of a double play, and costs the defense nothing to prevent because there is nothing to field.
Counting home runs is simple, which is why the stat has been the headline number for a century. What it hides is everything around it. Two hitters with 35 homers can be a full win apart if one walks 90 times and hits .280 while the other walks 30 times and hits .225. The home run total is identical; the production is not.
That is why NUT builds on wOBA rather than home run totals. wOBA gives the home run its real run value — about twice a single — and then counts everything else at its real value too. A slugger with a low on-base percentage still grades well; he just does not grade as if the homers were the only thing that happened.
What is a good HR?
Home runs move NUT more than any other single outcome. wOBA weights a home run roughly twice a single, so a power surge shows up in a hitter’s NUT faster than any other kind of week.
