Betancourt and Batista, You Both Suck

Combined, you are on the order of 6 wins worse than average over a full season. (Assuming Yuni's a -10 defensive shortstop, which is being generous).
In bRAA (wOBA-based) and pRAA (tRA based), your Seattle Mariners:
Yes, I know. But Kenji doesn't completely suck at defence.
Bahahahahahaha how is this possible.

This is what inspires me to be an alcoholic
I fucking hate you Mariners

And Kenji's line manages to be worse.

Top three hitters:
Raul, Greg Norton, Felix Hernandez.
Your 2008 Seattle Mariners.

Lopez was just at +4 about a week ago :(

the wOBA's were corrected a few days ago.
I wasn’t counting RBOE amongst the league totals due to a SQL issue. So 2007 and 2008 individual values went universally down.

Felix, in one at bat...
Twice as valuable at the plate as Ichiro all year.
That blows my mind.

It would likely go way down if he had more AB's
The small sample size skews it.

Also
You can find this sort of thing for each team at StatCorner. Which I would totally be pimping even if I didn’t help run it.

Is there a reason you have O-xO but not R-xR?
by Fogel on Aug 27, 2008 7:54 PM PDT up reply actions 0 recs
We don't have R yet.
Requires doing some extra work that we haven’t got around to (and is why we don’t have SB/CS either)

On one hand, our rotation has been worse than theirs, but on the other hand, Jesus at least we have some green pitchers
by Fogel on Aug 27, 2008 7:52 PM PDT reply actions 0 recs
None of their guys are particularly far below average
thus, they pwn us

How much of an adjustment do SS get?
I’m guessing average SS is probably -5 to -10 offensively so Yuni isn’t quite so bad. This makes him around -20 compared to average SS out there. He still sucks but Vidro is worse because an average DH is probably 10 runs above average so Vidro was around -25 runs and that was in less playing time.
by Edgar for Pres on Aug 27, 2008 8:04 PM PDT reply actions 0 recs
DH is -5, SS is +10 IIRC
And defence matters.
by Graham on Aug 27, 2008 8:10 PM PDT up reply actions 0 recs
Almost
The position adjustment levels, as developed by Tango:
Catcher: +15 runs
SS/CF: +5 runs
2B/3B: No adjustment
LF/RF: -5 runs
1B: -10 runs
DH: -15 runs
The gap between an average SS and an average DH is about 20 runs. So, yes, Vidro is still significantly worse.
by davidcameron on Aug 27, 2008 8:23 PM PDT up reply actions 0 recs
How bad is Yuni's D?
He’d be within half a win if it were even -10. Although not by rate, obviously.
by Graham on Aug 27, 2008 8:25 PM PDT up reply actions 0 recs
It's bad
Fielding Bible +/- has him at -21 plays so far this year, which would be about -15 runs. They had him at -10 plays last year and -3 in 2006, so Dewan’s system sees the same ridiculous collapse of defensive value we’ve all noticed.
So, yea, you can argue that Vidro and Betancourt have hurt the M’s about equally this year, though it took Vidro about half the playing time, which makes his remarkable suckitidue more impressive (depressive?)
by davidcameron on Aug 27, 2008 8:28 PM PDT up reply actions 0 recs
8.3% LD%
He and Carlos Marmol have basically identical line drive rates, and they’re lapping the field (among pitchers with at least 50 IP). The next best guy after thsoe two is Scott Downs at 12.3%.

one question
I"m kind of new at this, so I have a question. When looking at bRAA and pRAA for the entire league, most players are at negative values, and there are a few people like Pujols and Cliff Lee with such high values that they seem to be skewing the average upwards. So when we look at these numbers, is 0 still what we are considering average despite possible positive skews? And would batting/pitching runs above median provide better information regarding who has been playing better or worse than most?
by boomdonkey on Aug 27, 2008 8:37 PM PDT reply actions 0 recs
No - average is in relation to the whole, not the number of players that are better or worse
an “average” player is never an actual player on some team, but a concept of what would happen if you took all the players in the league at one position and lumped them into one, dividing by 14. Essentially.

Graham/Matthew
What is the median bRAA and pRAA? A distribution would be even better. A PA/IP normalized distribution would be the best. If this takes more that a few minutes though then don’t bother.
by Edgar for Pres on Aug 27, 2008 8:56 PM PDT up reply actions 0 recs
It's something we'll put up eventually
But it’s not to hand, so will have to wait.
by Graham on Aug 27, 2008 8:58 PM PDT up reply actions 0 recs
`
For all batters: -1.20
For PA > 100: -2.25
For all pitchers: -0.36
For xIP > 15: -0.24
by Matthew on Aug 27, 2008 9:03 PM PDT up reply actions 0 recs
FWIW, there are not surprsing values
players that suck don’t get the chance to rack up huge negative RAA totals like players that excel are able to do with huge positive RAA totals. So yes, there’s skew but I’m pretty sure the overall talent level in the major leagues is not a normal distribution.
by Matthew on Aug 27, 2008 9:06 PM PDT up reply actions 0 recs
Incidentally Tango has looked at this a little bit
by Jeff on Aug 27, 2008 9:11 PM PDT up reply actions 0 recs
Yeah, one of the interesting things myself and the Wharton group found when doing research for SAFE
was that on an individual talent basis (things like arm strength, power, velocity), MLB almost always had close to a normal distribution. It’s just when you put it all together than you introduce the tail distribution (with playing time moving it back toward normal)

I also have a question
Isn’t wOBA, much like prOPS, rooted in a hitter’s balls in play? Shouldn’t Beltre look much better then in terms of bRAA?
by CKel on Aug 27, 2008 8:45 PM PDT reply actions 0 recs
No.
wOBA = (0.72xNIBB + 0.75xHBP + 0.90×1B + 0.92xRBOE + 1.24×2B + 1.56×3B + 1.95xHR) / PA
by Matthew on Aug 27, 2008 8:46 PM PDT up reply actions 0 recs
Would it be not worth it to apply the prOPS formula to wOBA?
by Fogel on Aug 27, 2008 9:05 PM PDT up reply actions 0 recs
PrOPS has a good goal but poor execution.
It’s discussed in the “A Common Mistake” thread.
by Matthew on Aug 27, 2008 9:07 PM PDT up reply actions 0 recs
Right but wouldn't it be better than nothing?
Maybe?
by Fogel on Aug 27, 2008 9:12 PM PDT up reply actions 0 recs
It'd be taking a great stat and half-assing a regression for luck.
I (and maybe others if I can convince them to help me out) will be working on a robust way of actually doing this in the future.
by Matthew on Aug 27, 2008 9:15 PM PDT up reply actions 0 recs
Attempt
if you apply Beltre’s career LD/GB/FB/etc. outcomes to his 2008 performance, you come out with a wOBA of .327.
This, of course, makes him come out worse since he’s been in the Majors from a young age at which he hadn’t yet fully developed his power. So in reality he’s been better than that figure would suggest.
by Jeff on Aug 27, 2008 9:23 PM PDT up reply actions 0 recs
Ah so the outcomes as opposed to the type of hit
Thanks

You may have explained this and I'm not seeing it.
But Fangraphs has Betancourt at -29.74 (-7 worse than Johjima). Is there a reason for the discrepancy?
...and now I'm here
by Librocrat on Aug 28, 2008 3:34 AM PDT reply actions 0 recs
Fangraphs' BRAA is based on run expectancy.
Wheras BRAA based on wOBA is not. So Fangraphs takes into account how many runners are on base and how many outs there are. wOBP does not.
There may be more to it than that, but there’s one difference.

So is Yuni basically the model of Replacement Level Player?
Or is he even worse?
by Jed MC on Aug 28, 2008 8:09 AM PDT reply actions 0 recs
Depends on his defense.
I’d think he’s worse than replacement.
by Matthew on Aug 28, 2008 9:34 AM PDT up reply actions 0 recs
I'm having trouble reconcilliing that, judging from wOBA*,
Angels stadium is somehow simultaneously assisting our hitters AND pitchers at the same time. This seems logically impossible.
~Till the Halo burns out...
by Zu Long on Aug 29, 2008 9:37 AM PDT reply actions 0 recs
That's really, really weird
Angels stadium apparently inflates singles and doubles while repressing line drives, and since the first two go into wOBA and the last one goes into tRA…
by Graham on Aug 29, 2008 10:19 PM PDT up reply actions 0 recs
Yeah, I figured as much. And more than likely it's the singles that really kill us.
107% is more than anyplace else in the game IIRC. There are so MANY singles in a give season that even after it’s halved, that’s a huge boost to our expected runs. I’m honestly not sure how you adjust for that.
