There are more things in heaven and earth than are dreamt of in your philosophy, and the Arizona Diamondbacks are a phenomenon far beyond the range of our poor instruments.

Consider the Toronto Blue Jays, as we often do. They've scored 585 runs this season and allowed 546. Pythagoras has turned a stony and hostile gaze upon pretty much all of the AL East this season, so the Jays sport but a 65-64 record, rather than the 69-60 mark you would expect. So they've been a little unlucky - not as unlucky as the Yankees, but OK.

Meanwhile the Diamondbacks have scored 551 runs and allowed 584. And what is their reward for scoring 34 fewer runs than Toronto and allowing 38 more?

The second best record in the National League. They've won 73 games and lost 57. They have a better record than the Yankees.

The Diamondbacks have done this sort of thing before. In 2005, they scored 696 runs and allowed 856 - they could have been expected to post a 64-98 mark, and losing 100 games would have been quite reasonable.

But, as history tells us, they didn't lose 100 games - they went 77-85, beating their Pythagorean expectation by a whopping 13 games. Extensive investigation showed that to be the 7th luckiest season of all time.

Well, folks. This year they're going for the record.

It's a tough record to break - it's held up for more than a century. In 1905, the Detroit Tigers played like a .418 team - they scored 512 runs and allowed 604. A 64-89 record was the expected result. Somehow, some way, the Tigers pulled off a 79-74 mark. They won 15 games more than expected, their winning percentage was .098 higher than expected. And the rookie from Georgia probably had little to do with it - Ty Cobb hit .240 in 41 games after joining the team at the end of August.

No other team has over-achieved to such a degree. No one's really come close.

But the Diamondbacks of 2007 are taking a run at it. Here are the 10 greatest over-achieving teams in baseball history, along with the 2007 D'Backs.

1918 BRO N 126 57 69 .452 360 463 -103 | .377 47 79 10 .076

And you probably noticed that the top ten includes some short 19th century seasons, the war-shortened 1918 season, and the strike year of 1981.

So how is this happening? Is Bob Melvin a genius? Discuss among yourselves.

By the way - the 2005 Diamondbacks played Troy Glaus and Royce Clayton on the left side of the infield. So maybe that's what Ricciardi was thinking this year. Change the luck. Worth a shot, anyway.

So I go over to catch up on what's new at the Hardball Times - and great gosh almighty, Chris Jaffe is looking at this very issue. He has an explanation - the D'Backs are good in one-run games, and get smoked in blowouts. This is pretty much always the case when a team exceeds their Pythagorean to such a degree, but he's looked at the nuts and bolts of it. Arizona has what he calls a bi-polar bullpen. The relievers are either really good, or they're having the Kerry Ligtenberg Meltdown Experience. So if the starter is having a lousy game, Melvin goes to the dregs of his bullpen. Rather than lose by five runs, they lose by ten or twelve.

This, by the way, is more or less what happened in 2005. That year's Arizona team went 1-11 in games decided by eight runs or more and were outscored by 120 runs in those 12 games alone.

Last night was all set up to be a classic "luck" Pythagorean win for the Jays.  All the close plays going their way, with the clincher being the baserunner kill at third beating the runner to the plate at a key moment in the game.  Then, the club totally blows the "luck" win by scoring 4 gratuitous runs in the ninth.  They just can't do anything right!

There is a lot I don't understand about just how useful these statistics are but I find them interesting. The whole Pythagorean seems so overly simplistic, and it seems like the discrepancy between the estimated team record and actual team record should go beyond luck. Is it the best predictor of Wins/Losses though? Better than, say, some combination of team ERA and runs per game relative to league average? Is it fair to say that the relationship between pitching and batting is non-existent? i.e. whatever a teams pitching performance happens to be on a given day has no bearing whatsoever (psychological or otherwise) on the teams hitting and vice versa. It seems somewhat counter-intuitive that a teams hitting performance and pitching performance are completely independent of each other, given you always hear about strategies changing based on the score, but perhaps the key to winning games is simply COINCIDING enough good pitching performances with good hitting performances. Luck will dictate when the two will match up in the right way. Does that make sense? And do the statistics support this?

I know it doesn't happen every day, but a single 30-3 loss would totally distort a club's Pythagorean for the entire season, wouldn't it?  Have it another way and spread it out as three 10-1 losses, which doesn't seem unreasonable for any team, even a good one, and you've got the same effect.  Perhaps we shouldn't be worshipping at the temple of Pythagorus any longer.

Here's Rosenthal's take: http://msn.foxsports.com/mlb/story/7137338

No one worships Pythagoras.  We do know that Pythagorean record for a club in 2007 is a useful indicator of how the club is likely to do in 2008.  It's not the only thing, though.
Magpie - Sunday, August 26 2007 @ 04:41 PM EDT (#173581) #
Two reasons why they're useful: a) the vast majority of teams will be within a couple games of their expected records; b) large blips tend not to repeat themselves. A team that is 10 games over (or under) its expected record one year will probably be right on it the next year (or tending the other way) the next.

Which is why the Diamondbacks are so interesting. They're doing it, and on an historic scale, again. This is really, really strange.

There are basically two things that skew actual records away from the Pythagorean expectation: one-run games and blowouts. The best minds of our generation have reluctantly concluded that the biggest variable in one-run games is just dumb luck (although reasons for the specific failures of specific teams can be identified with more precision, there is nothing - absolutely nothing - common to all teams that are lousy in one-run games).

And it acts like a random thing. A team can have a lousy record in one-run games one year and be perfectly fine the next. A good record in one-run games usually isn't the mark of a quality team - it's the mark of a lucky team.

Blowouts, on the other hand,  are generally more significant. The ability to beat the other team senseless really is characteristic of a quality team. Which was a large reason it was pretty easy to expect the Cleveland Indians to have a much better record in 2007 - they went 18-26 in one run games, 16-9 in blowouts. No team with a losing record had ever outscored their opponents by 88 runs until the 2006 Indians came along.

But the Diamondbacks are good in one-run games and lousy in blowouts. This is new. Once could be random... twice could be a coincidence.

I guess...

I thought that the D'Backs might not be quite as lucky using 2nd and 3rd order wins, but they're pretty much the same as normal pythagoras.  And if you used pythagoras the D'Backs would be in last place in the NL West.

The Mariners are also overachieving by 7-8 wins as well.  Hard to believe they're in the WC lead.
