How do I find total runs created on offense?

0 votes

I'm looking for something similar to wRAA + UBR here, obviously. 

I want to see the total number of runs a player has added offensively - plate production and all base-running (i.e. 'normal' base-running and SB/CS) - with park, league, and other sensical adjustments. 

But I don't want to see this number relative to a AAAA player, or on an average scale, or on any other kind of scale.  I just want to see, simply, how many runs a player added offensively over a given amount of time. 

Is there such a statistic available, or at least a means to calculate it?

Thank you very much in advance!

Sounds like you want wRC.


With the new changes to wOBA et al, however, SB/CS have been removed from wRC, so you'll have to do some math to extract out the 'average' from wSB and UBR if you want to combine them to make an offensive stat that pays no attention to run environment.

The fact that sabermetrics can't answer a simple question like this - "How many runs did (Player A) contribute on offense this season" - speaks volumes.

If I'm a general manager, and I'm looking to sign someone, or to trade for someone...here's what I want to know.

1) How many runs per game will this player add offensively (plate production and all base-running).

2) How many runs per game will this player save or cost us at the positions we're considering playing him at.

3) How does that player's total run production per game compare to other players we're considering?

That's all we need to know.  And sabermetrics tells us, seemingly, everything else.



Well, firstly, Fangraphs does not account for all that us offered by 'sabermetrics'.

Secondly, Fangraphs does offer many answers to the question you've asked, just not in the very specific manner you are asking.
#3 is the important question, and you can use wRAA, wSB, UBR, UZR, and other metrics that compare to average.  I don't know why you need raw totals, but you could take James' advice to make them.

Here, let me attempt to start-over...I want to look at these stats as a general manager would (not as a sports-writer voting for awards would, in which case WAR is fine). My interest is in putting together the best hypothetical team. So, there are two numbers that I want to see:

#1) How many runs per game does a player produce offensively? (plate production and all base-running...sb/cs and normal base-running).

#2) How many runs per game does a player save or cost at each position he's played on defense?

I guess I'll attempt to break the reasoning down step-by-step..

...Seperation of "Total runs added per game" on offense and defense. I'm David Dombrowski. There's an opening at short-stop in my lineup next season. There's someone available I'm interested in signing. I want him to play 160 games at short-stop next season. But he split time at short-stop and second base last season. The problem with his WAR number is that it tells me how productive he was at both positions, and I'm only interested in how productive he is as a short-stop.  So, I take his "total runs added per game as a hitter," and then I add it to his "total runs added per game as a short-stop". Now I can accurately compare him to other potential short-stop additions.

..."Per game" terms (or per inning, or per plate appearance, etc.). I'm David Dombrowski. There's an opening somewhere in my lineup. I'm looking for someone to come in and give me 160 games there. I'm interested in knowing how productive a prospective player should be in 160 games for us next season; not in how productive he was in 140 games last season (due to injuries, limited playing time, etc.). So, I want to see this all in per-game (or something similar) terms.

..."Total runs added" terms. I think that "total runs added" is the perfect, single, all-inclusive number to compare players by. I think that converting this number to a 'relative to AAAA scale,' or to a 'relative to average scale,' or to a 'wins' scale is unnecessary and confusing. I'm David Dombrowski. I'm considering adding one of two players. How many runs should player A add? How many runs did player B add? Good, now I can make an easy choice.

So, I guess what I'm looking for is 1) the raw run total numbers of wRAA + UBR, and 2) the raw run total numbers of UZR at each position (then I'll divide them per game).

...Where can I find this?

1.  UZR is broken down by position for each player, and positional adjustments (per 600 PA) are found here.  Offense by position is found on the splits page, though there usually isn't much difference in career numbers by position.

2.  With per game totals, you need a lot of decimal points to avoid rounding errors.  Having a table of 0.00424's and such looks poor and takes up more room.  If that's something you want, the tables are able to be exported, and you can make them on your own.

3.  I'll just do this by example.  Let's say an average player creates 80 runs a year.  If Player A creates 95 (+15 wRAA) and Player B creates 85 (+5 wRAA), the two numbers end up with the same difference.  As long as the two players are on the same scale (average, replacement, zero, etc.), the comparison is very easy.

I don't think raw numbers are necessary, since someone will always fill the innings that a player isn't on the field.  That is why replacement level was created.  The other stats measure from the average mark, which is the same for every player, aside from league, park, and opponent adjustments.  This site, or any site, can't have every single detail you are looking for, but the ability to export the spreadsheets gives you the power to do so.  The stats on this site should be sufficient for any statistical analysis you are looking for.
