Revisiting Kevin Millwood's Strand Rate
On July 2, R.J. Anderson had a post up at FanGraphs that led to a huge internet uproar. The premise was that Kevin Millwood wasn't pitching as well as his ERA indicated -- his ERA was being driven by an unsustainably high strand rate of 86.9%.
Anderson argued (and I agreed) that this wasn't because Millwood was getting more ground balls or digging deep within himself to make a great pitch in key situations...rather, it was owed primarily to simple dumb luck.
And less than two weeks later, where do things stand? Millwood's ERA has shot up by almost a run, of course...and not surprisingly, his strand rate has dropped down to 80.0%.
In other words, as one would expect, he's experiencing a regression to the mean. I expect he'll end up the season with a strand rate around 75% or so.
Millwood has had a nice season. But he's not been an All Star caliber pitcher, and he's not suddenly figured something out. He's pitching about as well as he has the last couple of seasons. He's just got a better defense behind him, and (up until the last couple of games) had been extremely fortunate in the results with runners on base.

Whatever...
Millwood’s results are his results. No need to try to tell us why they should be different when we all can see what is actually happening.
That’s simply using stats to try to paint an alternate reality… Dumb, dumb, dumb.

I really hope
this is a post made in jest.

Using stats to prepare us for what might happen
But even still, Millwood would give us a pretty good chance to win

No it's OK
It’s using normative data that correlates with what happened. Neither the data (nor Adam’s POV) are certainties that Millwood’s ERA will continue to climb, nor that his strand rate will continue to drop. Are those likely? Yes. Are they certain? No. Both strand rate and BABIP result from situational play, and you can’t see into the future to ascertain that sharp grounders will result in either base hits or double plays. OTOH if his LD% shoots up, that can affect all his numbers. Can’t predict accurately if he gets fatifued, and whether or not that causes some loss of command, or how different batters in matchups will handle his pitches. One SSS weirdness was Rob Johnson’s HR – whodda thunk it?

I disagree
that because someone is having part of their game looking overwhelmingly good due to fairly flukish numbers, that they aren’t an all star.
If you have 100 RBIs at the break, like Juando, or are hitting .400 or close to it, or if you won every single game, but your FIP shows you are a fairly average player, you are still an All-Star in my book. I’m sure Hank Blalock is pretty happy that guys with a fluky half season get in.
Its just an exhibition game anyway.
Sure, the whole :Kevin Millwood’s strand rate was really good because he really knows how to dig down was a load of crap, but still, I think he should have been in over Wakefield in my book. I’m just not motivated enough about All Stars to start a half dozen fanposts though.

I'm curious
Why AJM shares Josey’s obsession with self-congratulation when a fairly obvious prediction occurs.
I have something to say here
…but I don’t want to offend Adam, whom I like. The other fellow I mentioned…well I’ll just say he was probably denied certain activities as an adolescent.
As far as his bringing it up, it’s likely because so many people disagreed with him.

Well
I never disagreed, I just wondered what he thought it “should” be. He’s answered that now, though I don’t know why there’d be any reason that strand rates would be consistent from season to season (although, looking at the numbers, I guess they are—for Millwood, anyway).

A fairly obvious prediction
like all Blalock needed was to stop being dicked around by his organization?
My self-congrats were well earned because every other dumb mf in LSB sat there with their thumbs up their ass while that was happening to Hank (and the team).
And Gardner, let me know when you have the onions to make one prediction that wasn’t obvious.

I don't make any predictions
Because I don’t give a shit about being right about anything.
But I do love that you think your online baseball predictions are a sign of your manhood.

Make a prediction
or give an opinion ahead of time that nobody else can see, Joe College Pussy.

Make a prediction?
How many times have I and others asked you for your prediction on how many games the Rangers would win and you’ve refused? I even offered to bet you on that issue. All you’ll throw out are the Vegas and Pecota projections yet you never say if the Rangers will meet or exceed those.
Don’t ever accuse others of refusing to take a stance on an issue.
Remember Red, hope is a good thing. Maybe the best of things. And no good thing ever dies.
Excuse me?
I said before the season that the Rangers would go 73-89. That prediction now looks very failed (I’m ecstatic to probably be wrong).
Vegas & Pecota weren’t THE reasons for that prediction but I used what they said as part of a blend of information and then formed my own opinions.
I said before 2008 the Rangers would go 76-86 (which ended up being their actual pythag record) and said in January 2007 that the Rangers had “75 win talent” (they went 75-87).

I'm not a big fan of luck.
A pitcher having a good year probably subscribes to the dictum “there is something I can do here to influence the situation in a positive manner”. “There’s always one last thing I can do”. You know, the Hal Moore shit. These are a bunch of numbers out there on a ball field. They’re human beings and they fight.
Then again, shit is what it is and believe me, I know luck exists. I don’t want to believe it’s luck when something good happens to me. I want to believe it was because I did something to cause it. And when I’m a fan of a baseball team, the same thing applies.
And then again, maybe it’s a little of both. Confidence goes a long way, no matter what a person does for a living.
But I don’t think Millwood is the same pitcher he was last year or the year before. His stuff is better and he’s not throwing nearly as many marshmallows. He’s staying on the corners a lot better. Maybe his stuff isn’t any better…I’m not in the batter’s box so I wouldn’t really know for sure. The location is better, though. You can tell by the kinds of swings guys are having against him.
I guess when you finally do get into better shape, it can’t help but to affect your attitude, and if you’re confident instead of pensive good things will tend to happen.
I’m not stupid. Luck exists in baseball like it does everywhere else in life, but I don’t think it exists to the point that some people who post here do. Baseball is a game of skill, not of chance.
good post
I don’t believe that predictive stats are all that informative when used in a forensic type way.
Sure Millwood’s strand rate is likely to go down, but that doesn’t mean we have to discount all the good games he has already pitched, as if he didn’t “deserve” the good games that he has already put in the books.
There's more to the picture than meets the eye.
This.

Millwood
Here’s an observation: I feel like there is a lot more discussion this year about how he is over-performing his peripherals than there was last year about how he was under-performing his peripherals (Dirkatron being an exception).
"Was this really necsarry?" - cowpoke/hurler hurley
Yeah
rightly or wrongly, Millwood is definitely under the microscope.

So...
if Millwood has just been luckier this year would it be wise for the Rangers to see what they could get for him now? I mean, if he is viewed as an ace right now the market for him would be pretty high, especially with the option year in his contract being basically a given.
If the Rangers could get a young ML ready starter back in the deal (obviously he has to have a decent ceiling) among a couple other prospects do you think about it?
