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.
CB Bucknor not having a good day....
Jesse Rogers [email protected] Yeah, there was plenty of chatter before the game about home plate ump today. Knew he would be a factor.
Jake Arrieta gives up first inning run
For the first time in a year, 33 starts.
Old news, sorry if it's 3/44-
J-Hey being classy by repaying an old teammate:
With Paredes moving to 3B, how do you see playing time shaking out between him and Galindo? Do you think Galindo gets starts at 1B? Galindo is more of a prospect than Paniagua, right?
Phil, your knowledge of the Cubs Minor League system is unbelievable.
This kid would be a key piece in a trade for a pitcher, imo.
This might be old news but Hammel was on ESPN 1000 and said that he changed his diet and workout routine over the off season and tweaked his delivery so it'd be more repeatable so he'd have a better second half. So...some cause for optimism anyway.
CHILDERS: RHSP Dylan Cease and LHSP Bryan Hudson are probably the top two SP prospects in the organization right now.
LHSP Jose Paulino has electric stuff (91-94 MPH fastball with sinking action and a mid-80's slider), but he also has trouble commanding it.
RHP Jose Albertos (2015 IFA - Mexico - $1.5M bonus) just turned 17 in November, and his fastball already sits at 95-96. He also throws a curve and a change-up, and is fairly advanced for a kid his age.
AZBOBBOP: Most of 2016 draft picks will get assigned to either Eugene or AZL Cubs, but the Opening Day Eugune roster will probably be almost 100% from the Extended Spring Training squad roster (pending the arrival of draft picks).
I think I can probably tell you which pitchers and players at EXST are in contention for roster slots at Eugene and which are in contention for slots with the AZL Cubs - AS THINGS STAND RIGHT NOW - (listed alphabetically):
* bats or throws left
# bats both
Eloy Jimenez atop the leader board for minor-league home runs in the Cub system, with seven. Tied with Balaguert and Vogelbach, two 24-year-olds. Jimenez won't be 20 until late November. Leads the Midwest League in SLG and OPS. Maybe he'll get promoted to the Myrtle Beach squad that visits Woodbridge, VA, in June or Frederick, MD, in August.
Watched two Pelican games at Frederick the other week. Was most impressed by Stinnett and Happ. Happ may swing harder than Javier Baez, though more compactly. (Also got to see Brockmeyer hit a bomb.)
E-MAN: Jose Paniagua isn't a string-bean, but I wouldn't say he necessarily bulked-up during the 2015-16 off-season either, He led the DSL Cubs in HR and doubles in 2014, and he showed XBH power when he arrived in Mesa last year, leading the AZL Cubs in HR, doubles, and RBI in 2015. It's just that he has taken his HR power to a new level this year.
Paniagua displayed plus-HR power in Cactus League Minor League Spring Training games in March, and that got him a slot on the South Bend Opening Day roster. But he was sent to EXST after only six MWL games.
More on the Cub Way.
Martinez is one of my least favorite pitchers in baseball. I'd love to see a game like yesterday's against him.
Send Soler down!
Awesome thanks AZ
Great report, Phil! This organization has so many hitters to be excited about.
