How about K-BB%+?

novaether

Just divide it by about 12%. It won’t account for park factors, but they’re so close to 1.00 for K% and BB% anyways, so who cares? It’s kind of a pointless exercise anyways, because what does it matter if David Price has a K-BB%+ of 2? That doesn’t mean his ERA should be half of the league average or anything.

What do park factors have to do with Ks and BBs? Don’t park factors only affect Balls in Play?

K and BB rates are included in the Park Factors information, and there are differences, park to park. Whether the differences are due to personnel, foul ground, the batter’s eye, players adjusting to expected run environment, some combination of factors, or merely meaningless variance has not, as far as I’ve read, been decisively established.

One of the factors is that breaking balls can be more or less drastic due to the humidity, I believe.

Great stuff with the additions. One request: Can you include RA9 in the leaderboards and player profiles? It’s better than ERA, and you already have RA9 WAR, so it’d make sense to add it. Thanks.

Would love to see both R/gm and RA/gm for team leaderboards, too.

Would a (K-BB%)/K% statistic be more useful? The closer to 1.00, the better. That way low strikeout pitchers who also have good control won’t get left out of the leader boards…Thoughts?

Stats aren’t made to put everyone on the leaderboards. They are made so the highest are at the top and lowest at the bottom. No need to be fair by giving everyone a chance to be at the top

Isn’t what you’re asking for just an obfuscated version of K to BB ratio?

Matt

Yep, it is just K/BB, but displayed strangely.

(K-BB)/K = 1 – (BB/K), which will be in identical order to K/BB.

What the hell is K-BB%?

I just use wins, ERA & WHIP.

Any idea on what a league average K-BB% is for some context? Thanks for the new leaderboard!

When you click leaders, at the top right there is a link called league. That’ll give you the league average.

The problem with K%-BB% is that they aren’t worth the same; one strikeout is less valuable than one walk is harmful.

Roughly speaking a K and a BB are equivalent. The differential works. Try to find some threads of mine.

novaether

Then why aren’t they weighted equally in FIP?

Sure, but according to Eno’s research there is no more predictive stat for in-season ERA than this one. That makes it useful.

Charlie Hustle

This!

There are many stats that could be derived from Ks and BBs, but K-BB% has been shown to be more predictive for in-season ERA (in some studies).

Compared to K/BB, K-BB% reflects the magnitude of the difference between K% and BB%. For example, take two pitchers with a K/BB ratio of 3. A pitcher with 9 K/9 and 3 BB/9 is a different type of pitcher than a pitcher with 6 K/9 and 2 BB/9.

Wouldn’t 2K%-3BB% be better (the same weights as in fip)

What does K-BB% represent?

Charlie Hustle

If reflects how pitchers dominate the strike zone.

For a nice explanation, go to Dave Cameron’s article from yesterday (5/20) entitled “A Graphic Look at Pitcher Types”.

Thank you. That’s all, just – thank you.

This a useful addition, and a clear indication that site management continues to listen to reader feedback on how to improve the site.

I continue to feel that I am getting my money’s worth from FG.

When in the “Customize” tab, I try to add “K-BB%” to my custom pitching stats list. But K-BB% is not there. How come?

Love the addition! Hey, I know it must feel like the peasants are at the gate with torches when you add a new stat, and I’d like to add one!! Surprise… The Great Dave Cameron mentioned a while back that wOBA could be added to the pitching stat line, the only access now is sneaking in through splits. Love to see it someday.
Thanks very much.

Will we ever get a version of FIP that matches WAR, though, with infield fly balls counted as strikeouts?

Can we get Pitchers RAA?

sheeks9

I dont like positional adjustments, I dont like League adjustments, I dont like replacement value, and because of that, I do not like WAR.

I use Bat, BsR and Fld for position players, and RAR for pitchers, but since the replacement value is added to pitchers it is tough to compare them to position players who I only look at RAA in their Bat, BsR, and Fld scores.

Also, if you could add up Bat, BsR, and Fld and make that one statistic, I would enjoy that as well.
