Partial Postseason Prognostication

With only a week remaining in the MLB regular season and only two races still undecided - the AL Central and NL Wild Card - we're seeing more and more articles seeking historical trends that predict postseason success. Last week, we linked to Lisa Swan's article about strong Septembers and Flip Flop Fly Ball's chart displaying the correlation (or lack thereof) between the having the best record during the regular season and winning the World Series.

Well late last week and over the weekend a few more of these pieces popped up and here are three of them (all via BBTF):

Similar to the chart at FFFB, Tom Verducci sorted the last 9 World Series winners by their regular season record and found an almost perfectly even distribution of League Championship pennants and World Series Victories. One championship came from each of the top 7 seeds and two came from teams seeded 8 or higher, such as the 2006 Cardinals who had the 13th best record in the league that year but still won the WS.

It's a pretty rough measure for a couple of reasons. The first, which Verducci points out himself, is that the teams don't play balanced schedules so teams get as much credit for the record in the NL Central as they do in the AL East, and so forth. Secondly, in 2006 for instance, four of the best 5 records came out of the American League. As a result there was an artificially higher chance of a low seed winning a pennant and a World Series (which happened with the Cardinals) since three of them were on one side of the bracket.

----

Next up, Dave Cameron wrote a piece for Wall Street Journal's website which showed that over the last 7 years, the teams that won the World Series have had a relatively small amount of meaningless games leading up to the postseason.

Dave quantifies "meaningless" games as ones that were played after their team has locked up a postseason berth either by winning their division or securing the Wild Card, but doesn't count ones that factor in the race for homefield advantage or are played against potential postseason opponents. Those certainly are played with a higher level of effort and urgency that the ones the Yankees are about to play against the Royals, one would assume. As Rob Neyer points out, 7 years is also a pretty small sample size.

----

Lastly, we have a piece by Lincoln Mitchell in The Faster Times which would seem to fly directly in the face of the half-baked theory proposed by Jeff Pearlman that we took issue with last week. Mitchell attempts to identify the team with the best two starters each year and concludes that since 1995, that club has won the World Series only twice.

There are problems with this methodology as well. ERA+ is not a bad measure but it certainly is not conclusive in determining the team with the best two starters when the postseason rolled around. Furthermore, if we wanted to do more of a complete assessment, we would rank each team's top two pitchers, or better yet give them a score on a scale of, say, 1-10 which would more accurately display the difference between each duo. In some years the top two hurlers for the best team might get a "9" and the next best team only receives a 6, but a straight ranking wouldn't convey that. Once the scores were determined then we could look at the results and see how they correlated with postseason success. Then we might have a better picture of how having two dominant starters predicts playoff series victories.

Do you notice a theme developing here? These methodologies are all pretty incomplete. A huge part of the problem is that baseball is littered with variables, there is no control group and you can't just create situations and run them over and over. Of course it's much easier to point out the deficiencies of these findings than take the time to complete the analysis.

All of these writers are admittedly taking a "quick and dirty" type of approach to their analysis and that's completely understandable. At one point, I started a post that was similar to Lisa Swan's about finishing the regular season on a high note (but I wanted to look over the last 10, 15 and 20 games as opposed to the final month) but as soon as I figured out how many tedious calculations I was going to have to do and how much time it would take me to do even a couple years worth of analysis, I scrapped it.

Another factor that makes it difficult to go more in-depth is that, ideally, you want to have a point when you are done with your research. These pieces were written for online outlets where time is always of the essence. You don't want to spend a bunch of time and at the end of the post have to say, "Through all of this research I determined that there is no noticeable correlation in the data."

And this brings me back to a piece that we looked at back at the end of August by Jay Jaffe of Baseball Prospectus. Jaffe brought up the research conducted by Nate Silver and Dayn Perry that lead to the creation of BP's Secret Sauce and applied it to this year's playoff picture. The difference here is that the Silver and Perry went into their research testing all sorts of variables and determined that strong defense, a pitching staff with a high K/9 and strong closer all had high correlation to postseason success. The Secret Sauce is the closest thing we have to a scientific study of what teams are "built for the playoffs" and it's still fairly incomplete.

In all likelihood the Yankees will take the long ALDS, so we still have over nine days before the first postseason pitch is thrown. We're to see more attempts at unlocking the postseason code and they'll probably be pretty interesting. But I highly doubt any of them are going to take the time to shift our thinking with a truly in-depth study of what October baseball really comes down to. Let's just try to enjoy the fact that the Yanks can coast home, throw out their B and C line ups and take things as they come.

Game 155: Guilty Until Proven Innocent

With the magic number for the Yankees to clinch the AL East and the one for the Red Sox to secure a playoff spot both sitting at 3, last night the Yanks took an important step towards preventing the Sox from sullying the visitor's clubhouse with celebratory champagne. With the Rangers' win last night, the Yankees can ensure that the Sox don't pop the bubbly at the New Stadium with two more victories and in the process, wrap up the division for themselves. The Yanks seem to be taking that apporach seriously, as they trot out the "A" line up again, including catching Jorge Posada in a (late) day game after a night game. [UPDATE 2:53 P.M.: According to LoHud, Posada has been scratched with a stiff neck. It's been bothering him since the Jesse Carlson incident nearly two weeks ago]

Unlike last night, the starter climbing the mound for the Red Sox is the one with something to prove. Daisuke Matsuzaka has managed to generate a lot of buzz during the two starts he's made since emerging from his exile in Fort Myers but objective observers still have some questions as to whether he's really "back and better than ever".

His first start was quite excellent but his last one against the Orioles was a lot closer to the old Dice-K: decent results but inefficient with his pitches. He threw 110 of them over 5 1/3 innings, allowing 8 hits and three runs. He walked away with the win, but the myth of the new and improved Matsuzaka took a bit of a hit down in Baltimore.

For whatever reason, Matsuzaka is being discussed as a "weapon" in the postseason, but CC Sabathia is considered more of a liability. CC is 8-0 in his last 10 starts dating back to the beginning of August and the Yankees have won every single one of those games. Over that time he has an ERA of 2.24 and struck out 77 while giving up just 55 hits and walking only 17. You'd think that that people might be making a bigger deal out of this. After all, he just signed a monster contract this offseason and plays for the best team in baseball.

However, just like Zack Greinke's terrible team makes it harder for his great season to be recognized, the fact the the Yankees have already pulled away from the pack means that Sabathia's great stretch gets largely swept under the rug because it doesn't appear to factor into the playoff race either. The problem with this logic is that if CC was pitching poorly, his team would be a whole lot closer to the pack.

Part of the equation is that Sabathia is as pure of a late-season pitcher as there is in the game. His career ERA in September and October regular season games is 2.67 and his next closest month is August at 3.14. His ERA in all other months is 4.01. Maybe writers feel like they've heard the story before. But more likely, it seems that they want to talk about his lack of success in the 5 starts he's made in the postseason. It seems he's a choker until proven clutch; guilty until proven innocent.



Look in my eyes dog, right in my pupils
If I'm your rival, why would I have to do you?
Press try to throw dirt on my name, disturbin' my game,
Seemed happy when they heard he was arraigned.

Game 150: I Need To Know

This afternoon in Seattle, after a last second loss on Friday and a dominant win yesterday, the Yankees square off in a rubber match against the Mariners. Aside from the full slate of NFL games, two interesting match ups are taking place earlier in the day with implications to the playoff picture.

The Twins could pull to within one game of the Tigers with a win against them today which is important because the winner of the AL Central most likely facing the Yanks in the ALDS. Also, if the Rangers lose to the Angels, the Bombers will be in position to officially clinch a playoff berth by beating the Mariners. The Yanks would probably rather gain some cushion for home field advantage over the Angels because the Rangers are going to disappear from the picture soon enough, but those are some things to watch for.

Going for the Mariners this afternoon will be Ian Snell. After starting off the season poorly for the Pirates, Snell actually asked to be demoted to AAA back in June, citing "too much negativity" concerning his performances from the fans, media and even some bloggers. It was widely considered that he would be traded from the Pirates after the demotion and was, shortly before the non-waiver deadline. He, along with shortstop Jack Wilson, were exchanged for 5 minor leaguers, including catching prospect Jeff Clement.

Snell took Jarrod Washburn's spot on the roster after the lefty was shipped to Detroit, but hasn't performed well in his place. He has a 4.86 ERA in 9 starts but has averaged just over 5.0 IP an outing and has walked 30 while striking out 25. He's 4-2 over that stretch, but the team is only 4-5.

Joba Chamberlain toes the rubber for the Yankees this afternoon, making his 5th artificially shortened start in a row. His last time out was the most encouraging of the bunch, lasting 4 innings against the Angels, with the only run coming on a solo homer to Vlad Guerrero. He still wasn't especially efficient, needing 67 pitches to get those 12 outs, but it was an improvement over his previous efforts.

With only two starts remaining after this one in the regular season, Joba should be cleared for 5 innings this time out in order to work up to being fully stretched out for the postseason. It would be nice to know Joba is on the right track for October and good performance today would be a big step in that direction.



I need to know (I need to know),
Because I don't know how long,
I can hold on,
And if you're makin' me wait,
If you're leadin' me on,
I need to know (I need to know),
I need to know (I need to know).
