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.
if they dont win at least 130 games this season they can pack it all up, turn wrigley into a concert venue, and move the damn team to san jose.
I see where catcher Cael Brockmeyer was promoted to Tennessee a couple of days ago, to fill a roster spot vacated by David Freitas, recently promoted to Iowa. Caratini is the other catcher at Tennessee.
They've already clinched a minimum winning percentage of .607 for the month, and that's only if they lose the last 2 games. If they win both, they can push that up to .679. So much for "stumbling" in May. When you're winning over 60% of your games, you're doing baseball well.
If the best walk-off hit possible is a solo home run in a zero-zero game--Eloy did it tonight!
(But maybe it's a grand slam when your team is down three? He didn't do that.)
Number eight for Jimenez. His team is 31-17. Yesterday they scored 17 runs against Lansing. Two weeks ago it was 15 runs against the same team. This is a nice team, South Bend. The Cubs must have had a good draft last year.
Tonight the pitchers were Sands, Brooks and Effross.
He'll be fine. He's not some wimpy young pup.
In all seriousness the Cubs have the fewest amount of games played in the NL which means they're gonna be facing quite the grind later on including 24 games in a row at the end of June and beginning of July so I hope he does get a few days off.
Meh. He only got one hit today. Maybe give him a rest?
Good thing the Cubs have five left-handed batters in the lineup. Velasquez is just tearing thru the righties [edit - doesn't seem to faze Bryant!]
ben zobrist gets to ride up front tonight cause he's a good guy at sports.
cubs with a 5 run lead and a lackey shutout through 3ip \m/
HAGSAG: I have not seen Joe Nathan out on the field, but he is supposedly at the UAPC.
ERIC S: Best outing I've ever seen from Manny Rondon, and I've seen most of his outings since the Cubs got him from the Angels.
M. Rondon is competing with six others (Dylan Cease, Bryan Hudson, Jose Paulino, Pedro Silverio, Jesus Castillo, and Erling Moreno) for a starting slot at Eugene, and (as you can probably tell from the EXST box scores) the competition has gotten fierce over the last couple of weeks, With the exception of Moreno, the Eugene SP candidates have upped their game lately, and M. Rondon's outing yesterday was especially impressive/dominating.
E-MAN: Pierce Johnsion was mixing a 92-94 MPH fastball with a plus-change-up AND curve, and he threw strike-after-strike-after-strike with all three of his pitches. I believe that was the best command and pitch-efficiency I've ever seen from Johnson, who often pitches from behind in the count and issues too many walks.
Of course now he has to avoid a recurrence of the lat strain (whch he has had previously in his career) as well as all of the other miscellaneous physical problems he's had over the last three years (hamstring, quad, back, etc).
PHIL: Any movement on P. Johnsons pitches? What was his "out" pitch? I know he was working on a 4th pitch, so wondering what he is looking like these days. Thanks.
AZ Phil, has Nathan showed up in Mesa yet? Thanks.
