Is anybody familiar with this Total Zone Runs stat? www.baseball-reference.com/about/total_zone.shtmlI can't really understand how it's calculated and how accurate it is... The reason I'm asking is because since I had time to goof off this morning, I was looking at stats from this season and going through the defensive stats for MLB... and Judge leads in TZR in RF with 17, which I thought was weird with how much time he's missed. Hicks is 5th in CF and he's barely played this season!!! LeMahieu is 3rd in 2B with 9... and he only had about half a season at 2nd base this year... actually less than half. So my question is... is this stat really flawed or are our players just THAT good at defense??? |

And if the stat isn't flawed and they are that good... imagine how great it be if they had a full healthy season

That calculation may be like UZR/150. If it is, then a number is reached by using the formulas you showed and then calculating a total per 150 games. In that way number of games played does not hurt, nor harm in attempting to demonstrate a day to day effectiveness.
That’s just a guess as to why we would have players with few games played, but very high ranks...

I think all of the defensive stats are interesting but none are prefect. It is increasingly hard to factor in the extensive value some teams add through defensive positioning. The Yankees put a lot of analytics into that.

Not only are defensive stats unreliable to some degree or other. A couple games ago Mike Ford hit a soft towering fly ball to left field. No one is home and it drops... for a double. With the shift on, no one was there to catch it, yet not only does Ford get a cheap double, but one or more fielders are held “responsible” in the world of UZR/TZR.
Official scorers constantly mystify with their judgement, as do umpires. In the end stats give us an approximation of what’s happening. Gio Urshela is not getting credit for his defensive skills, yet we see him make incredible play after incredible play and we know he’s one of the better third basemen in the game.
Looking at all stats draws a better picture of truth than any single stat, but in the end you still have to use your eyes...and even then, if you don’t know what to look for, that can fool you...

I actually don’t know whether or not they’d be considered responsible for that in those metrics. That’s a good question. For what it is worth I don’t think any professional teams rely on those metrics. They are paying a lot of money for play by play statistics that evaluate what’s actually happening on each play not these more mass consumer stats that are really just by and for fans. |

That would make sense that it's taking the stats that are currently available and extending them through a season to make a player with 50 games comparable to a player with 100 games. I never even considered that
