How is the ARM stat calculated?

[venflaalachi]

The title is the question, how is the ARM fielding stat calculated? It seems in previous versions of OOTP the ARM fielding stat correlated somewhat with the arm rating for outfielders, but that hasn't been my experience so far with OOTP 25. I get players in my league putting up what seems to be pretty high ARM stat without getting any outfield assists, and it is messing with the gold glove award for outfielders.

For example, this player won the GG for CF, despite the fact he doesn't seem very good at fielding. He also had 0 OF assists but put up 19 ARM from CF.

Looking at my league history, the best arm marks are almost exclusively from poor overall fielders.

The numbers can get pretty extreme in small sample cases of guys playing where they probably shouldn't. One example is a guy that played 533 career innings in CF with a -10 ZR and 14 ARM (most of career was spent in corner infield and rightfield). The top of the career list is loaded with players that fit this profile.

ARM (outfield arm runs): Outfielder’s get credit (plus or minus) depending on what the runners do on a hit or a fly ball out. A runner can stay put, advance, or get thrown out. A fielder will get credit not only if he throws out more than his share of runners, but also if he keeps more than his share of runners from advancing extra bases.

It’s a bug. Not yet addressed but known. Seemed to be more how calc’ed for presentation than affecting plays when it was uncovered. I’m unsure the status of any further investigation into it.

Thanks for the heads up.

Yeah, something seems to be going on with UBR and ARM. We'll look into more and should hopefully have some fixes.

Quick question for the OP:

It looks like through 111 starts in the outfield he has not been credited with a single outfield assist? Is this accurate?

Is the ARM bug generally found among outfielders or only those who also play some in the infield?

Anyway, disappointed to hear about this and UBR. Really, “disappointed” is a charitable characterization.

I sim out games and and only play playoff games, but the stats say he didn't get a single outfield assist, so i do think that is accurate.

As to the second question, not sure, but I see in my games that the outfielders with strong arm fielding ratings (70+ on the 20-80 scale) that tend to lead the league in outfield assists tend to have a negative ARM stat, and they do not play in the infield.

I'm disappointed as well since it does impact who wins GG for outfield, the other GG winners make sense. For now, I've taken over control of the awards so the right people win the GG for the OF. Hope it can get fixed with the next patch.

I will admit that part of my concern is related to the black box game engine. I would hope that these ratings are actually being used for resolving plays, and not as a means of distributing certain credits and debits in various statistical accounts. My confidence in this as a default assumption, however, has ebbed as more and more superficial additions (Statcast “data”, etc.) and statistical book-balancing post-event modifiers without clarifying their actual utilization.

I mean, if guys aren't running on you at all and you get no baserunner kills, that's still usually pretty good (although as noted the way the stat is being calculated is off and they're working on fixing it). I will say that IME I think the game is a little bit too cautious of guys with good arms in the outfield and at catcher in general although that's one of those "general feelings that might not be supported by the stats" things.
