Beware the BABIP
I harp a lot about BABIP (Batting Average on Balls in Play) and how it's a good indicator if a player is due for a slump or a rebound from year to year, and even within a season. The general guideline is that a player will generally settle within a range of .290-.320 on their BABIP, with the league average being .300 for a hitter and .290 for a pitcher. Now pitchers have much less control over their BABIP than hitters, that is unless they throw a knuckleball or particulary good change-up that is hard to get good contact on, but hitters actually can outperform or underperform that guideline quite significantly thanks to an ability to hit line drives, speed and a few other minor factors. That being said, they don't outperform it by that much. If you look at the 3-year leaderboard for BABIP on Fangraphs, only three players have topped the .360 mark (Jeter, Holliday and Chipper Jones with Ichiro just missing). Now those are some of the best hitters in the game and their career BABIP's are pretty high as well (except for Chipper who has a .328 career BABIP) and it's been shown that players regress more towards their own BABIP levels than the league averages. That all being said, when you see a player hitting anything over .340, you need to start worrying that it will fall back a bit unless they've been able to sustain it for a few seasons. On the flip side, if a guy is suddenly below .280 he's either had a really unlucky season or he's about to leave major league baseball (see Jones, Andruw).
People smarter than me and with way more time have been trying to calculate exactly what influences BABIP and a recent study posted at The Hardball Times has made some headway on the topic. Now with the advent of keeping track of batted ball types (line drives, ground balls, flyballs, infield flys, etc) a bit of an illuminance has been shed on the subject. At one time, it was suggested that if you add .120 to a hitter's line drive percentage, you'd get a fairly decent approximation of what their BABIP should be...the harder you hit a ball, the harder it is to catch it.
That recent study broke down BABIP even further and came up with a better mousetrap to guess what a player should be doing using speed, line drive percentage, ability to hit to all fields and much, much more. The results are interesting and their model seems to be the best estimator out there at the moment.
I've listed the Cubs results below but let me explain an interesting discrepancy. Fangraphs has their BABIP for each individual season and their career and that's what you'll see in the first three columns, their 2008 BABIP from Fangraphs, their career BABIP from Fangraphs and the difference. The BABIP for 2008 in the spreadsheet provided by the authors of the THT article differs slightly and is said to be taken from Baseball Prospectus. Why the difference? I'm not sure, but I assume they calculate it slightly differently and why that is I don't know, but know that the BP BABIP numbers are lower than what Fangraphs calculates, although generally just a few points. To compare apples to apples, the second three columns compare the BP calculated 2008 BABIP versus their xBABIP as the THT article calls their new BABIP estimator. And for some reason, they don't have an entry for Mike Fontenot for 2008.
|Player||2008 FG BABIP||Career BABIP
||2008 vs. Career||2008 BABIP||2008 xBABIP||2008 vs. xBaBIP|
So whatever column you're looking at, you can see the Cubs hitters certainly enjoyed some good luck last season. Almost across the board they outperformed their BABIP for their careers and what they should have gotten in 2008. Sobering news indeed...
Now, I would also kind of expect that from the number one offense in baseball, you'll get a fair amount of luck coupled with career years and the Cubs still out-OPS'd the Cardinals by .014 pts (who had a few of their own career years) and the Phillies by .027 points (the Phils offense is just good), so they have a bit of a safety net for the eventual fall the offense will likely take in 2009.
Individually, I'm particularly worried about Theriot and Miles, and expect a pretty decent drop in their numbers. And while I do get on Theriot's case a lot, I will say that my observation has been is that he does have a knack for getting the sweet spot of the bat on the ball. The more you do that, the more solid contact and line drives he'll hit and the more the ball will fall safely for a hit. But I still expect his numbers to drop in 2009, although maybe not quite as steep as 30-40 points off his batting average. I already expected Bradley to fall of from his .999 OPS, and hell, he could drop 100 points off that OPS and still be the Cubs best hitter in 2009. The xBABIP estimator doesn't look good for Soto, but he's young and we don't know his career baseline yet and he could suffer a drop in his BABIP and make it up for it with more power as he's still just 26 years old this year. If Reed Johnson gets to hit mostly versus lefties, I'm not worried about him dropping too much either.
I know I mentioned two articles for today, but one of the twins has been pretty sick, so you get one. We had three articles yesterday plus a game thread, so plenty to scroll back on and enjoy during today's off day.
No idea what will happen. The Cards are the Cards and they have come back from 2-1 holes twice in the last 4 years, so I don't see them in panic mode at all. If anything, I expect the Cubs to be pressing more than the Cards today.
I want the Cubs to win because it would be great for the city, and great for the fans. But more than anything, I want the Cubs to win so I can see this team play for at least one more week this year. Never enjoyed watching a team more than this year.
Just to remember how far we have come: last year's opening day lineup was Bonifacio, Lake, Castro, Rizzo, Olt, Castillo, Schierholz, Barney, and Samardzija. It's been a fun ride this year!
BRADSBEARD: I haven't noticed any new rule or a change in the interpretation of an existing rule happening in Advanced Instructs, I don't know what rules will be tested in the AFL, although almost all recent rule changes and new interpretations of existing rules (the home plate collision rule, replay, time clock between innings, et al) do get their start in the AFL.
AZ Phil: I've heard that the AFL will be testing out a new force out rule that would affect break-up plays (like the Utley play). Have you heard anything about this new rule and any details about it? Are they testing it out at the advanced instructs as well?
Pretty sure I already know the answer to this, but since I will be in NYC next week I want to confirm... If the Cubs were to advance to the NLCS, the winner of LAD/NYM would have home field based on being a division winner (as opposed to Cubs by virtue of better record), correct?
CUBSTER: This "hammy" is on the other leg I heard last night. See you at the ballyard today young man!
Oh what do you know, Cubster? Go back to your day job.
--- Ducks, puts on Cardinals cap, runs.
Russell had a severe hamstring last year while with the A's system, forcing him to miss the first half of 2014. I've even wondered if his injury last year was a component of Billy Beane putting him on the trade market. He was quoted saying that last year's injury was a 10 out of 10 when it happened. Last night he said his hamstring soreness was a 1/1.5 out of 10. Hamstring injuries are tricky though, so I'd expect the medical team to be overly cautious here.
...I want to reinforce the observation that there was no sea of red in the crowd. The usual Cardinal fans roaming the stadium were few and far between.
Also, almost every 2 strike pitch brought the fans to their feet. Good for those in knee rehab.
"1st team hit hit 6HR in a game in the postseason." rises above obvious...i checked it with the official fact-finding commission of Douche, Douche, and Douchestein. they agreed with you, but they're a bunch of f'n douches so who cares?
btw, the cubs are 2-1 in the post-season series.
I should be able to watch the game on the NFL replay app, whatever that thing is called. I've got it on my iPad. This is the first year I haven't forced myself to somehow watch every game - no I take that back, last year was - in quite some time. Last year was so unbearable, no pun intended.
You make some good points about Cutler, and I was a holdout defender of Cutler for a long time. I gave up on him a bit after one too many dumb interceptions, but last year doesn't count. Trestman was the worst coach in Bears history.
Nice little reportage there!. I think you're older than me. Considerably older. Maybe several generations. Working out is so essential, especially as age kicks in, isn't it? I still lift weights, and so I'm confident that when I get to be at the hip breaking age, mine won't be a statistic. But I have a ways to go for that to be a concern.
What was impressive to me is that the Cubs won despite poor base running, several defensive miscues, Russell leaving due to injury, Arrieta having an off game and getting knocked out early, and Rondon giving up 2 runs in the 9th. If they can win a game like that...
I was there too. The crowd was absolutely electric. People were standing for every big and semi-big moment, from the first inning on. It felt incredibly strange and exhilarating to see the Cubs (the Chicago bleepin' Cubs!) score playoff insurance runs on the Cardinals. What a game. One to remember.
