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.
I'm kind of nostalgic for the Schwarber-for-Miller rumors.
This offseason, after some ridiculous playoff run and Chapman saving every game from here until the end of the postseason striking out 27/9innings, I welcome anyone to quote this thread and call me a dummy: I hate this trade, and my hate is 2 parts Chapman makes this team less likeable and 1 part that's a ridiculous overpay for 30 regular season innings and, at tops, 10 postseason innings. Already hoping they don't extend him.
btw...Thanks AZ Phil. I'm really enjoying your take on this trade.
I'm a bit disappointed on the Warren experience. Essentially they gave Castro away for crickets (OK, well they signed Zobrist with the Castro salary dump). Otherwise one might look at it as Chapman for Castro and our #1 minors prospect (Torres) + McKinney/Crawford. Seems pricey for a 2 month rental. We will see if this price tag is that steep in a relative way based on the remaining deadline deals for relievers.
Yep. One of the great things about this team (in addition to being really good at baseball) was the "likable" factor. Feels a bit different now. Who knows...maybe Chapman will be the king of the dance parties.
Here are some possible corresponding minor league moves we might see in the aftermath of the Chapman trade:
SOUTH BEND to MYRTLE BEACH: OF Donnie Dewees and INF Bryant Flete
EUGENE to SOUTH BEND: OF Robert Garcia and INF Vimael Machin
There is really no reason to replace Billy McKinney at Tennessee because both Chris Coghlan and Jorge Soler are doing their rehab at Tennessee.
And there are plenty of pitchers at Iowa. No need to replace Warren at AAA. .
I am 70 years old. The Cubs last played in the World Series in 1945. I was born in 1946. I hate to lose a prospect like Torres, but when the opportunity is there to get that World Series ring, you go for it. This was the idea in stock piling all this young talent. I would like to see Reddick added now and the Cubbies should be done.
I would expect Richard to accept an optional assignment because based on how he's played this season, there is a decent chance that he won't find work elsewhere. Rather stay and potentially get a ring. Same goes for Coghlan since he's struggled mightily this year.
Edwards should not go down. He's pitched very well and Maddon is very impressed with him. I would expect Grimm to go down for Cahill so he can get back on track (he's pitched better in July, but he's not getting enough appearances).
chitownmvp01: Indeed Clayton Richard would seem to be odd man out once Chapman reports, but Richard might accept a minor league assignment if he is promised a return to Chicago on 9/1 when MLB Active List rosters expand (Richard has minor league ioptions left).
The only player in the deal that would cause me a second thought is Gleyber Torres.
McKinney and Crawford are decent prospects but both are redundant/replaceable in the system and Warren was really only a middle-reliever or #6 starter, so to me it's really just Torres for Chapman.
There is no Comp pick for players traded mid-season. 2+ months of Chapman is it.
to get one of the best you have to give up one/some of your best...but it's a bit painful to watch the system's best prospect walk for any 2-3 month rental, especially one that's not an everyday player.
I assume Chapman will replace Richard on the roster, but who goes down when Cahill gets activated? Maybe Grimm?
And when Soler and Coghlan get healthy, how do they fit them on the roster when they're ready to be activated?
We are giving up a lot, but it's not like we're trading Addison Russell for 2+ months of Jason Hammel. When impact players become available, they are going to cost you. The other bids could also have been high.
Having Chapman as a rental is potentially less disruptive than having him come in with an extension in place.
Billy McKinney had season-ending knee surgery last August and came to Minor League Camp this year somewhat restricted. (He was used mostly as a DH in Cactus League Minor League Camp games), and I'm not sure he's 100% right now (he's repeating AA, and his XBH numbers are way down, like he's not getting good rotation in his lowev half). That might have been part of the reason why the trade wasn't completed right away.
Rashad Crawford was a basketball star in HS (he was known as "Baby Jordan", and baseball was only his second sport) and he has plus-speed and athleticism, so when the Cubs drafted him (Keith Lockhart was the scout) he was seen as a long-term project.
I was at Fitch Park the day that Rashad Crawford became a LH hitter, He waa never a switch-hitter, He went directly from being a RH hitter to a LH hitter, which I had never seen before.
