Fun With RE-RA9

Right off the bat, I have to tell you that I don’t love the name I gave the statistic I created last week. RE-RA9 doesn’t exactly roll off the tongue. The concept – adjusting run-scoring statistics to account for inherited runners – is easy to get your head around, and I think it’s clearly interesting. But while I had fun writing that article, I wasn’t quite happy with where I left off, either on the name front or on the analysis front.
The name thing probably can’t be fixed. I’m not a great namer of things, historically, and I don’t think that’s going to change today. But while I can’t do anything about that, I quickly expanded my coverage from 2026 to, well, as much of baseball as I could. If this statistic is interesting, it’s interesting as much for its application throughout history as for who’s good and bad at it this year. So with the help of the FanGraphs play-by-play database, which stretches back to 1974, I built RE-RA9 for the vast majority of the era where there were enough relief appearances for this statistic to even make sense. Forget Grant Anderson and Chase Silseth, the two poster boys from my first article. Let’s get some famous guys and seasons in here.
For example, here are the 10 pitchers who have done the most to prevent inherited runners from scoring (RE-RA9 lower than actual RA9), minimum 1,000 innings pitched:
| Pitcher | IP | RA9 | RE-RA9 | Diff |
|---|---|---|---|---|
| Jesse Orosco | 1296 | 3.56 | 3.17 | -0.38 |
| Trevor Hoffman | 1089 1/3 | 3.12 | 2.78 | -0.34 |
| Bill Campbell | 1177 2/3 | 4.05 | 3.76 | -0.29 |
| Arthur Rhodes | 1187 2/3 | 4.24 | 3.99 | -0.25 |
| Jim Gott | 1120 | 4.39 | 4.16 | -0.22 |
| Rollie Fingers | 1065 2/3 | 3.07 | 2.85 | -0.22 |
| Kent Tekulve | 1436 2/3 | 3.30 | 3.07 | -0.22 |
| Lee Smith | 1289 1/3 | 3.32 | 3.11 | -0.21 |
| Joaquín Benoit | 1068 2/3 | 4.08 | 3.88 | -0.20 |
| Craig Lefferts | 1145 2/3 | 3.85 | 3.65 | -0.20 |
