Petrillo: New Defensive Metric

I always denigrate metrics that include faulty defensive components as a way of evaluating players. Looks like they are working on improving this.

Certainly not just a deconstruction of Mike Trout.

Very interesting. Thanks for posting this, weams.

So Mancini gets a better jump on balls than Mike Trout? And Rickard gets the 5th best jump in the game?

You are very welcome. When Frobby and I were discussing my reluctance to use metrics with flawed defensive data, this came up. I think we are headed towards some good components sooner rather than later.

Yes. Jump, the metric. Trout runs better routes and is much faster. Bradley gets great jumps but often heads the wrong way. Corey Dickerson was a godhead of this.

Anything to make us feel better about who we've got on our team.

How the Orioles’ OF fared:

Rickard 0.7 + 0.6 + 0.2 = 1.5

Mullins -0.7 + 0.9 + 0.7 = 0.9

Broxton 0.4 + 0.3 + -0.2 = 0.5

Mancini 0.0 + -1.6 + 0.2 = -1.4

Smith -0.4 + -2.5 + -0.2 = -3.1

I feel kind of bad for Mancini.   He’s OK on the two parts where his natural speed doesn’t limit him.

But being real slow kinda limits you. Like to catcher or third base like Brooks.

Mike told me this AM that Nick Castellanos is an average defender in the outfield based on this year's http://m.mlb.com/glossary/statcast/outs-above-average

Do you agree?

Interesting. It's about time we had some better defensive metrics. Hopefully, these can be taken more seriously than the current ones.

All those numbers were right except Broxtons for some reason? FTFY.

How is Broxton incorrect?

[Sessh]

Looking at that link you posted, Broxton is 14th on the list at 1.1. Frobby had him at 0.5 behind Mullins. I corrected it and bolded it.

These data open up all sorts of interesting analyses. For instance, to get a comprehensive index of out getting skill should we really weight the component metrics equally and add them together linearly like Frobby did? Are some of the component skills more important than others? Do some age better than others? Can some be coached up more than others?
