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.
"An MRI taken Monday on the right side of Jorge Soler showed no major damage."
rare air though if he can keep it under 2. Sounds like Maddon already made up his mind though and Hendricks seems like the sort that would want to earn it. Guessing he gets a quick hook if he's still under 2 after 5 innings.
Fwiw, he can give up 1 ER in 5 innings (or more) and still be under 2. If he gives up 2 ER, he would need throw 9 IP to keep it under 2. 1 ER in 4 IP would give him an ERA of exactly 2.
In terms of WAR, it's still Scherzer by a lot (6.4), then Cueto (5.6), Lester (5.5), Kershaw (5.5), Roark (5.4), and then Hendricks (5.1)
Boring lineup tonight in terms of guys trying to reach milestones -- no KB (40 HR), Addy (100 RBI) or JHey (can he keep it going?), and Lackey isn't really going for anything, plus the team has already reached 100 wins. I get the "rest" thing, although they will have 4 days off after Sunday, but....bleh.
Agree -- I think you want to keep him on a regular schedule.
Ramos torn ACL
Sure, its not about his record.
Do you start him Sunday or not?
@jonmorosi Pitchers w/ sub-2.00 ERA in year of 185+ IP this century: Pedro ’00, Clemens ’05, Kershaw ’13/’14, Arrieta ’15, Greinke ’15, Hendricks ’16.
Yeah -- that would be rough for him. But, Monty is getting people out, he's a lefty and he has experience working out of the bullpen. Hammel? None of the above.
even if he's not starting, abandoning hammel would be a bit of a 'screw you.' i think it might be -monty +hammel, but it's speculation.
either way, someone's gonna be disappointed.
Joe said he is leaning towards 11 pitchers and 14 position players.
- 4 starters, Chapman, Rondon, Strop, CJ, Wood, Grimm, Monty. No dice for Cahill or Smith.
- 3 catchers, Rizz, Zo, Addy, KB, Javy, Heyward, Fowler, Soler, Coghlan, TLS and then Sczcur over Almora?
Cubs 3B Jason Vosler made two really bad throws on consecutive AB in the 8th. Fortunately the game was no longer in doubt at the time
The first one was a one-hop lob that allowed the batter to reach base on an infield single, and the second was air-mailed so far over the first-baseman's head that it went over the fence and landed in Field #4.
E-MAN: Despite the HR, Donnie Dewees is really more of a slash hitter (the HR was an opposite-field line-drive) who can accumulate lots of doubles & triples. He's also a good bunter and can get on base that way, too. Although he was thrown out trying to steal in the game, he's actually a good base-stealer and baserunner.
Defensively he has plus-range and tracks fly balls OK, so he can play CF, but he has a rag arm that requires the middle infielders to go out further into CF to make relays.
I don't know how many of you remember Bobby Knoop, who played 2B for the Angels, White Sox, and Royals back in the day, but he is a coach-emeritus for the Angels, and works with the infielders at Minor League Camp, Extended Spring Training, and Instructs. He's pretty spry for a 77-year old, and he really knows his shit.
With a big lead, Chapman was throwing sliders and changeups, something he's reluctant to do in a save situation. (Len and Jim covered this.)
Maybe they have a bad owner, I don't know, but they still have players and fans and a franchise, all devastated by this loss of life. Plus, everybody who follows baseball is a fan of a guy like this. It's why I used the word tragedy, which other people throw around but I try to be careful with.
I'm at an age where I remember old incidents better than recent ones, but I have to go back to Herb Score for something as disturbing.
That was Dee Gordon's only HR this year. Wow.
