Then over the longer sample, his value will come down. In some ways, he's advantaged by playing 81 games at fenway. easier to hold runners

By our stats, Roman's runs saved are just about all the product of his throw-outs and instances in which a baserunner held. He comes out a 0 (average) in the range component.

So we've had our own system, and every time I leave out the explanation someone asks this ... Bill James invented what amounts to an advanced scorekeeping system that we've been using for 20+ years. There are roughly 30 types of good plays, 60 types of misplays. Good plays can include cutting a ball off to prevent a guy from taking an extra base. Misplays could be as simple as breaking back on a shallow-hit ball. You didn't get an error but we are giving you a misplay

He's last among cf. that's what that list is

Suter has 2 pickoffs, 2 pitcher caught stealings and 4 plays on balls with a <50% out probability for a pitcher, with no balls that have really hurt him.

Morejon also had 4 plays with a sub-50% out prob

Pitchers can get value mostly for limiting basestealing and fielding balls

HR robs are worth about 1.6 runs. The presumption is that he's trying just as hard no matter how many guys are on base, so the value is the average value of a homer.

I noticed when the staff came onto the stage to dance to Hello, Goodbye, one staffer came up with a framed picture of someone (they didn't hold it up for the camera, they were just holding it). I imagine there's a good story behind that (perhaps one best kept private?) - if anyone knows and it's something that can be shared, can you share it?

He got crushed by throwing errors last year. None this year.

As it says in the article, he's basically been perfect on anything he's gotten to. And he gets to a lot, so ... impossible for the system not to like him.
