Dear MVP Voters...

...if you must vote for a player on a playoff team, please vote for Derek Jeter. You guys go on and on all the time about how valuable he is to New York, and this may be his most valuable year yet. His defense has been very good: by UZR, only two shortstops have saved more runs this year with the glove. He's hit for average (0.329) and, for a shortstop, power as well (17 HRs). He's stolen 22 bases and only been caught 5 times. He's got all those intangibles.

You may be tempted to vote for Mark Teixeira. Mark's been a better hitter than Derek, but not by as much as you probably think. Don't be swayed by his RBI and HR totals. They are not spectacular totals for a first baseman. Furthermore, who do you think he's been driving in? Derek Jeter, that's who. First baseman who can do what Mark does are much more common than shortstops who can do what Derek's done this year.

Look, things can change in the next month, but I implore you to look beyond a few somewhat gaudy numbers and appreciate the man who really makes the Yanks go. You assure us all the time that the game isn't about numbers. That it's about people. Prove it. Vote for the guy whose value is tied up in more subtle things than RBIs and HRs. Vote for Derek Jeter.*

* Personally, I'd vote for Joe Mauer and then Ben Zobrist before Derek, but if you think being on a playoff team is important, Derek's your man.

**UPDATE** Never mind. Derek just sacrifice bunted with a two run lead in the second inning, no one out, runners on first and second, and Jose Contreras struggling. This is a terrible, terrible play, for which Michael Kay is rightly excoriating him, noting that Derek is a great hitter having an MVP type year. Al Leiter is trying to defend him, but it's a real reach. It doesn't matter that Derek leads off now (not that lead off hitters sacrifice bunt a lot anyways, Al). It doesn't matter that it's small ball. You can't give up outs in that situation. You just can't.

Atrocious Wednesday Night Broadcast

I've been watching (on my DVR) tonight's broadcast of the Yankees and White Sox on ESPN2. The broadcast team is Dave O'Brien and Rick Sutcliffe. I mean no offense to either of these guys personally but...

This broadcast is seriously awful. It's completely unfocused and disjointed. Sutcliffe just rambles about whatever the hell he feels like, throwing out random and asinine assertions left and right. Every correlation is a causation. Every random anecdote "tells you something." It's just stunning to me that these guys can blabber on for three hours and say nothing important or relevant.

If I'm not mistaken, Sutcliffe chose Derek Jeter as his pick for greatest shortstop OF ALL TIME. I love DJ, and that's just flat out insane.

Also, it seems like A-Rod has fielded every single ball in this game. That's weird. And now Jorge Posada is hurt. That's just awesome. Crap.

Anyways, let me apologize for this post. I assure you it is more informative than tonight's broadcast.

The White Sox fail horribly

In the bottom of the second inning against Boston today and leading by the score of 2-0, the White Sox found themselves defending against a first and third situation with two outs. The runner on first, J.D. Drew, attempted to steal second base and the White Sox had him thrown out by thirty feet.

So what happened? They got him in a pickle and while they wasted a bunch of time trying to tag Drew out, the runner on third, Jason Bay, scored. The second baseman, Jayson Nix, even checked the runner on third before continuing with the pickle.

Now, it's not clear to me from the replay when Bay started running or how close the play might have been. It doesn't really matter though, because it's horrible baseball. If Bay was stealing at the same time as Drew, then the catcher should have simply held on to the baseball and put Bay in a pickle. Bay knows this. Everyone knows this. Thus, it stands to reason that Bay waited until he saw that Drew was in trouble. This is standard baseball fare: when a runner gets caught in a pickle, other runners try to advance.

What's really surprising is that the White Sox appeared to trade the run for the out. Let's look at the math:

Run Expectancy for possible outcomes:

Runner on 2nd, 3 out, 0 runs scored: 0.0. In this scenario, the White Sox throw home and get Bay out. I expect that this is what usually happens.

Runners on 1st and 3rd, 2 out, 0 runs scored: 0.54. In this scenario, the White Sox simply chase both runners back to their respective bags and fail to record an out. It is also our baseline scenario.

Runners on 2nd and 3rd, 2 out, 0 runs scored: 0.58. In this scenario, the White Sox prevent Bay from scoring, but allow Drew to take second. Note that it is almost no worse than the baseline and far, far better than any of the next two outcomes.

No one on base, 3 out, 1 run scored: 1.0. This is what actually occured.

Runner on 2nd, 2 out, 1 run scored: 1.32. In this scenario, the White Sox fail to get either runner and they both advance, scoring Bay.

The White Sox would have gained .42 expected runs by simply hanging on to the baseball and letting Drew steal second! Then, after throwing through, they chose not to throw back home, preferring not to risk 0.32 expected runs for the chance at -1.0 expected runs (the difference between the best and worst outcomes and what actually happened, which was itself the second worst outcome). In order for that to be a good play, you would have to believe that you had only a 25% chance at throwing Bay out. This strikes me as fantastically unlikely. It honestly seemed as if the White Sox were consciously trading a run for an out. If so, that is a gross misunderstanding of the costs and benefits involved.

And as I am typing this, the epic FAIL continues. With the bases loaded and two outs in the bottom of the third with the White Sox now up 4-1, David Ortiz dribbles a ball up the 1st base line. It's a fantastically easy play for the first baseman, who can tag Ortiz out by about 15 feet with plenty of time to field the ball... ...except Jose Contreras, the pitcher, runs over and muffs the play by trying to field the ball himself depsite the fact that he has a terrible angle on the ball and the runner. Run scores, no one out. It's actually stunning how bad a decision this is. Even if he picks up the ball cleanly, he has a tougher play than the first baseman.

He then walks in a run, throws a wild pitch to tie the game at four apiece, and servers up a three run bomb to Basil Rathbone Mike Lowell for good measure. Thanks for nothing, White Sox!

Falsifiability

Why do we believe any given proposition? To my mind, there are two valid reasons for belief in any proposition. First, your belief may be logically derived from a set of axioms and other derived true propositions. Not many beliefs fall into this category because truly axiomatic propositions are not in great supply.

So what is the other valid reason for believing in a particular proposition? In my opinion, it is also valid to believe in a proposition if the balance of evidence shows it to be likely to be true. For many propositions, it is appropriate to consider both the truth and falsehood of any particular proposition according to the likelihood that each is the correct value of the proposition. For other propositions, the nature of the evidence is such that it is not worth the effort to consider the likelihood that it is false because this possibility is infinitesimal. Whether or not one should factor the likelihood of a proposition's truth value into any decision is directly related to the costs and benefits of the possible consequences of the decision.

However, even when it is highly likely that a proposition is true because of the nature of the evidence for it, you must go one step further if you desire to be truly veracious. You must be able to identify those conditions that are sufficient to disprove the proposition you believe. You must show how the proposition is falsifiable.

If you cannot identify these conditions, then you do not have a reason for believing in that proposition. You must admit to yourself that the evidence that you are using to support your proposition is simply confirming a preexisting bias because no evidence would convince you to change your mind.

Indeed, the ideal is to identify the full set of conditions that falsify the proposition. It is quite easy to identify a highly improbable criterion to falsify a proposition. We should not take satisfaction in this. If there are other falsifying conditions, we need to identify them too. Otherwise, we will build a disingenuous shield around our cherished biases by finding only ridiculous falsifying conditions. This will give us the misguided self-satisfaction of believing that we are intellectually honest while stacking the deck in favor of not rejecting the beliefs we cherish.

Identifying a set of falsifying conditions is not easy. Indeed, it is likely that we will never fully identify the set of falsifying conditions for any particular proposition. Nonetheless, by seeking to know those conditions that will cause us to validly reject the things we now wrongly believe, we maximize the likelihood that what we believe will be true. That is the best we can do.

A-Rod is so clutch

BPro:
Contrary to his reputation, Rodriguez has actually been quite clutch this year; twelve of his 21 homers and 34 of his 63 RBI have either tied the game or given the Yanks the lead.
Of course, this has as much importance as all those statistics that people throw around when A-Rod fails to hit in the clutch: none whatsoever. It's just random, people. It's just random.

Rob Neyer on the MVP case for Mark Teixeira

Rob Neyer absolutely crushes the argument against Mark Teixeira for MVP. He's right in almost every way, from the general tenor of the argument to its finer details:
You know what? Let's just be honest. The argument for Teixeira is an argument for doing it the way it's always been done. Teixeira is just another big RBI guy on a team with a great record. If he were a Twin and Mauer were a Yankee, Teixeira would hardly be an afterthought.
Look, Teixeira's been great, but he's not even the most valuable Yankee: that would be Derek Jeter. Joe Mauer, despite missing a month, has been far and away the most valuable player in the league. That's what happens when you hit .377 with power as a catcher.

Look at it another way: Joe Mauer is the only player in the AL with an OPS over 1.000 (currently 1.071). In fact, it's nearly .100 higher than the guy in second place, Kevin Youkilis, who has a 0.988 OPS. Only nine players, Mauer included, have an OPS over .900. Again, Joe Mauer is a catcher.

The only way for Mauer to not be the MVP at this point (remember, anything can happen in the next month and a half), is if you believe that an MVP should come from a team in contention and that the Twins are not sufficiently in contention. Of course, you still wouldn't get to make Teixeira the MVP at that point. You'd have to find a way to get Ben Zobrist and Evan Longoria disqualified too. And, of course, then the MVP would be Jeter. Good luck getting him out of the way without disqualifying Tex at the same time.

The final word on New Yankee Stadium?

It does not appear that the ball carries well at New Yankee Stadium. In fact, it appears that it carries poorly. Nonetheless, it is very easy to hit a home run there. This implies that the fences are shorter than suspected. Details here (highly recommended).

I will note that this does not address how well the ball carried at the old stadium. It's possible, though I suspect not likely, that the ball carried very, very poorly at the old stadium so that the new stadium, while not absolutely high on the carry scale, still rates highly relative to the old stadium.

My bet is that the dimensions are slightly wrong. That seems to be where all the evidence is pointing.
