Looking at P/G for splits on the lineup page

[nivshah]

A user reminded me of this outstanding issue today:

Changes to the baseball lineup page

Sure. Using Cody Bellinger as an example: All Games: 128 G, 901.1 P, 7.04 P/G v. R 118 G, 632.2 P, 5.36 P/G v. L 86 G, 268.9 P, 3.13 P/G The split games are counting every game Bellinger faced either a lefty or a righty. So, it double counts the games when he faces both types of pitchers. Thus, it effectively has the wrong denominator when calculating the P/G.

For those of you in points leagues, are you fine with this weirdness, or would you like to see P/AB instead of P/G for position players? Or is there another solution I haven’t considered?

[Henry.Woodbury]

I’d like P/PA somewhere in the UI.

I too find the double counting problematic. The most useful report would be points per pa against righty and, separately, points per pa against lefty.

Is there a reason P/G is more interesting than P/PA for hitters in non-split situations?

[dalewilson13]

P/G is typically more interesting in that we earn points for each game. Thus, batters near the top of the order who get more PA/G are more valuable than someone of similar quality that bats lower in the order. But, for the purpose of the L/R splits, P/PA would work well as a proxy for P/G.

[jrgeyer]

What if it was broken down like P/4AB. That’s pretty much points per game.

[William_Wallace]

Ideal for platoon splits would be P/GS (vLH SP, vRH SP ). That incorporates both the split itself and the usage (b/c it counts all the PAs that you will get … or not get … if you decide to start the player vLH SP or vRH SP).

[legendaryan]

I do not find P/G very interesting because ‘game’ does not refer to any constant. More so with double headers currently only being 7 innings.

I realize hitters are tied to game limits, so a higher P/G is a desirable outcome for ottoneu owners, but when it comes to using it to evaluate how a player has performed against pitchers, points/g doesn’t give you as good an idea as points/PA, especially when you start to look at smaller samples.

I’ll time travel to 2018 and let past Niv know what dumb changes MLB has in store.

For my own analysis in FGPts leagues, I just look at wOBA for splits, which is effectively P/PA.

If you want to convert wOBA to P/PA for hitters, a handy formula is to just multiply by 6.5 and subtract 1 (there are variations on this, but that’s easy to remember). And then if you want to convert wOBA to P/G, multiply the P/PA times PA/G (this varies by typical lineup position).

So say you have a .350 wOBA guy who hits 2nd (4.55 PA/G). Then:

P/PA = (wOBA x 6.5) - 1 = (.350 x 6.5) -1 = 1.275 P/PA
P/G = P/PA x PA/G = 1.275 x 4.55 = 5.80 P/G

But if you’re just interested in P/PA, there isn’t much more than you need to make comparisons than wOBA by split since all the math behind it is just adding and multiplying by constants.
