The WAR stat and Youk

Friday, July 23rd, 2010

Yeah, I know I’m a biased Red Sox fan, and Kevin Youkilis is one of my favorite baseball players.  And I know that Youk is also one of the more despised players out there today.  But despite his much-ridiculed ever-changing facial hair, does he really deserve to get passed up for the All Star Game?  Cast aside by Yankees manager Joe Girardi for Paul Konerko?  And passed over by the fans for Nick Swisher?  Well, thank goodness someone more eloquent and more qualified than I spoke up about this recently.  One of our solid favorites, Joe Posnanski, threw it out there, along with a revisit of the WAR stat.  I’ve been starting to see WAR pop up more and more recently.  Although it’s more valuable for evaluating “real world” baseball value than fantasy baseball value, it would be interesting to do some evaluations DraftMVP-style using WAR.

Here’s the article, check it out:

Comparing baseball statistics across eras

Friday, March 19th, 2010

As fantasy data geeks of the highest order, sometimes we get carried away with analysis of stats in order to get that little *extra* edge in our fantasy leagues. However, after reading through this incredibly detailed research report on baseball statistics, we are humbled. It’s an incredible amount of work, with some fascinating conclusions and a whole lot of deep thinking about process and changes throughout time. Great stuff. Print it out, sit down with a few beers and enjoy!

A snippet from the summary of the report:

There is a long standing debate over how to objectively compare the career achievements of professional athletes from different historical eras. Developing an objective approach will be of particular importance over the next decade as Major League Baseball (MLB) players from the “steroids era” become eligible for Hall of Fame induction. Here we address this issue, as well as the general problem of comparing statistics from distinct eras, by detrending the seasonal statistics of professional baseball players. We detrend player statistics by normalizing achievements to seasonal averages, which accounts for changes in relative player ability resulting from both exogenous and endogenous factors, such as talent dilution from expansion, equipment and training improvements, as well as performance enhancing drugs (PED). In this paper we compare the probability density function (pdf) of detrended career statistics to the pdf of raw career statistics for five statistical categories — hits (H), home runs (HR), runs batted in (RBI), wins (W) and strikeouts (K) — over the 90-year period 1920-2009. We find that the functional form of these pdfs are stationary under detrending. This stationarity implies that the statistical regularity observed in the right-skewed distributions for longevity and success in professional baseball arises from both the wide range of intrinsic talent among athletes and the underlying nature of competition. Using this simple detrending technique, we examine the top 50 all-time careers for H, HR, RBI, W and K. We fit the pdfs for career success by the Gamma distribution in order to calculate objective benchmarks based on extreme statistics which can be used for the identification of extraordinary careers.

Introducing our weekly “Ask the Experts” Column!

Friday, March 6th, 2009

Welcome to our very first “Ask the Experts” blog post. After receiving requests from a number of you over the past couple years, we’ve finally given in and decided to devote some time each week to answering questions about draft strategy, specific players and statistical analysis. If you’ve got a question for us feel free to email us at experts@draftmvp.com or just comment on a blog post.

Our first ever “Ask the Experts” question comes from Erik in Boise, Idaho, who asks:

“Is Matt Holliday a 1st or 2nd round pick this year? What should I think about him after his move to the A’s?”

At DraftMVP, we LOVE questions like this because we can use statistics to really dig into the player and his change in home stadiums. Let’s break this down:

First, a little recap:

Matt Holliday PictureFollowing a very strong 2006 season, Holliday was projected as a solid 2nd round pick and his monster 2007 rewarded scores of owners who got him on the cheap. In fact, according to our super-secret DraftMVP ranking system, his 2007 stats made him the 2nd most valuable batter in baseball (note, this is without taking position scarcity into account).  That 36-HR/137-RBI/0.340-AVG performance easily pushed him into the 1st round last year.  We don’t need to tell the ’08 Holliday owners out there: 2008 was a disappointment. His power numbers dropped quite a bit. But, there was one bright spot: his surprise 28 SB’s gave him added value in standard 5×5 rotisserie leagues and in the process, confused most of the fantasy universe in evaluating him for ’09.

Will Matt Holliday continue being a stealthy stealing machine with the A’s?

It’s no secret that the Oakland A’s do not like to run risks on the base paths. Just take a look at the numbers:

Oakland A’s Team Stolen Bases
2000:  40 SB         (last in AL)
2001:  68 SB         (2nd to last in AL)
2002:  46 SB         (last in AL)
2003:  48 SB         (2nd to last in AL)
2004:  47 SB         (last in AL)
2005:  31 SB         (last in AL)
2006:  61 SB         (10th in AL)
2007:  52 SB         (last in AL)
2008:  88 SB         (7th in AL)

Yeah, we were just as surprised as you that they were in the middle of the pack last year but don’t be fooled!  The A’s had the lowest scoring offense in the American League with a young team that had trouble scoring runs.  Without someone able to knock in runs, they had to resort to an un-Oakland like offense and rely more on SB’s.  Their 1st half versus 2nd half splits also support this… as their RBI’s tanked along with their team SLG% after the All Star Break, their SB’s went up in a last ditch effort to get runners home.  With off-season moves for Holliday along with Jason Giambi, I think that the modest SB numbers for Oakland last year were an outlier rather than a trend.

The Bottom line: Don’t count on Holliday’s recent stolen base production. I think Holliday’s SBs are going to drop back to the 10-12 SB level. If he’s anything like the 2007 Shannon Stewart pickup, the A’s will let him run a bit and he won’t fall all the way to single digits.

Fine, enough with the baserunning, how about his power, is it coming back?

Even with last year’s power drop, Holliday’s stats still put him in the top 20 for batters overall (and top 10 for OF’s). However, a move from the hitter-friendly confines of Coors Field forces us to evaluate his home/away splits. Unfortunately, they don’t forecast well for his slugging numbers.  Take a look over the last 3 years:

2006 – 2008 Batting Splits

AB R H 2B HR RBI SO AVG OBP SLG OPS

AWAY 869  147  257  58  33  120  184  .296  .370  .486   .856
HOME 908  199  328  75  62  219  156  .361  .430  .669  1.099

Holliday may well end up a .300 hitter next year, with 40 doubles, 20-25 HR’s, roughly 100 runs and 80-90 RBI’s.  (runs and RBI predictions in “new team” cases are notoriously unreliable, however)  That would end up being pretty similar to 2008′s power numbers.

What does this all mean in fantasy?

Re-calculating my custom rankings puts him right on the edge of being a top 30 batter with stats strikingly similar to OF Nick Markakis.

In a fantasy draft, that puts him in the 35th – 40th pick range.

If the decision were between Holliday and Markakis, I would give a slight edge to Holliday since he doesn’t have to face the AL East Bos/NYY/TB pitching staffs for 57 games (and gets 19 games against the Texas Rangers!). Thinking about my own draft gameplan, I wouldn’t pull the trigger on drafting Holliday in the 3rd or even 4th round knowing that I can fill that OF spot with other near-equivalent guys a couple rounds later.  Holliday is just not a good value in early rounds this season, especially if it looks like you’ll still have a chance at players like Nate McLouth, Curtis Granderson, Bobby Abreu, and even Torii Hunter later in the draft.  I’ll gladly let someone else draft Holliday in the first few rounds and plug another position instead.  But if I’m looking for a well-rounded stat contributor and he’s still available in the 5th round, then I might be excited for a little Holliday…

Can A-Rod Do It?

Wednesday, September 10th, 2008

Last week I was scanning the HR leaders and Alex  Rodriguez, the perennial HR competitor leading the A.L. with 54 in 2007 was not on the list. What? Could the reality be catching up to the hype.

Say what you will about the end of the steroid era (see our post on if the Steroid Era really happened..) or the probability of an off year or the weakest Yankee batting order since the short and painful Garry Sheffield era… I know all these thoughts are going through your mind.

To address the most prestigious and recently tainted crowning achievement in all of sports, the HR record, we have to talk about pace.

Here is what I did. I plotted HRs/AB as the critical pace metric for Bonds, Aaron, A-Rod, and Pujols  – why not, right?

Take a look and draw your own conclusions. I want to hear what you think. Is A-Rod on track?

My team is Sick… not in the good way

Saturday, July 12th, 2008

Meet my team. A prolific roster of 22 studs top to bottom. I’ve got power, I’ve got speed, I’ve got K’s and SV’s. Favored to finish in the top and likely to take it all.

Then the season started and the injuries started to mount. Of 22 picks during the draft, 16 have missed considerable time due to injury or complete inadequacy (i.e. Rich Hill). We have 6 bench spots in my league; so really, I’ve lost my entire starting roster (check out the body count at the end of this post). 

The result of this horrendous luck? I’m in 15th place out of 16 teams.  I was convinced that I’d really angered the Fantasy Gods, and here at DraftMVP HQ, the guys were more than willing to make fun of my team. But as we started chatting about it, we realized that it wasn’t just my team that was weighed down by injuries. When Juan Pierre went on the DL for the first time in his career, we started to scratch our heads and ask “what is going on?” So, we dug into the stats and sure enough, there are some really interesting insights:

  • 2008 is already an atypical year with a much higher injury rate than any of the previous 20 seasons

  • Batters and Pitchers have been similarly impacted

  • The “studs” – year in, year out top picks – have been absolutely decimated. Take a look at the top 30 injured players – huge names in there

Batters Pitchers
Alex Rodriguez Jake Peavy
Jimmy Rollins Erik Bedard
Eric Byrnes Josh Beckett
Matt Holliday Daisuke Matsuzaka
Carlos Pena Fausto Carmona
David Ortiz John Smoltz
Curtis Granderson Chris Young
Alfonso Soriano John Lackey
Gary Sheffield Scott Kazmir
Albert Pujols Francisco Liriano
Troy Tulowitzki Rich Hill
Chone Figgins Chien-Ming Wang
Rafael Furcal Yovani Gallardo
Jorge Posada Pedro Martinez
Aramis Ramirez Kelvim Escobar

So what should you do about it? If you’re like me and your team is at the bottom of the heap due to some nasty luck, you need to get your roster healthy.. FAST. Here are a few tips:

  • Saving roster spots for guys on the DL is going to hurt you more than it has in the past. Several of your healthy players are likely to miss some time in the 2nd half of the season and each bench spot saved for someone who isn’t a predictable backup is a bench spot wasted.
  • You might want to hang on to guys like J.J. Putz, but for the most part, having a healthy player in hand is worth more than the player with potential. You need that flexibility in your roster.
  • Entertaining trade offers for your injured guys is always worthwhile, but this year it might be the strategy that helps you climb out of the cellar. Knowing what we know of the injury patterns, it’s pretty safe to say that you might be able to weaken other teams in your league by sending them some of your long-shots. Don’t be too proud to win at the expense of your competitionJ. On the other hand, if you’ve got a team that’s avoided major injuries and is at the top of your league, you have some different choices to make.

Some things you should be doing as we approach the All-Star break:

  • Take a hard look at your roster and figure out if any of your starters have a history of injuries and has thus far managed to avoid them. You should be thinking about trading them, right away.
  •  If, in addition to having some vulnerability in your starting roster, you’ve also got several players on your bench who fit this profile, you really need to cut some dead weight and get yourself more reliable backups.-          Say no to bargain trades for injured stars. They’re going to take up a roster space and expecting the player to come back and stay healthy is just wishful thinking.
  • Trade for solid backups. Depth at positions that are weak on the waiver wire (catchers, shortstops, second basemen) could be a good strategy.
  •  Place a premium on multi-position eligible guys who are healthy. Whatever you do, don’t close your eyes to this season’s reality: players are getting injured more often and if you haven’t bought insurance against it, you’re going to end up feeling some major pain in September.  

Let us know what you think – we’ll be taking a look at more of the stats around injuries in order to try and get some more specific advice together. If you’ve got some ideas on what to look at or how you’d think this through, just share them in the comments or shoot me an email at: cyrus@draftmvp.com

Did the Steroid Era Really Happen? And What Does it Mean to Me, the Fantasy Player?

Friday, March 14th, 2008

One man’s imaginary smack talk with Bud Selig *complete with graphs*

Now I may just be some skinny number-cruncher with a shiny degree from your average university with an abysmal male-to-female ratio, but I believe I may have caught some ground-breaking news that seems to have passed ole Buddy Boy by. So excuse me, commissioner Sir, if I fill you in on some of the things that have happened during your 1995-2008 beauty nap. Let’s see… well, we have a new president, grunge is dead, oh yeah and the game of baseball has totally changed.

How so you ask? Well take a gander at this here pretty chart.

clip_image002

The HR stands for homeruns, and that bouncy red line? You guessed it. Now, if I may direct your attention for one moment to the spike in 1987, which just so happens to be the year Mark McGwire broke into the big leagues with an eye-popping 49-homerun rookie season, and thus in the process planted the seed for the “Bash Brothers” era.

What? Aren’t doubles a better, more consistent indicator of power-hitting? Well, what do you know, I’ve got a chart for that too. Let’s take a look…

clip_image004

Wow, power-hitting really began to peak in 1998 didn’t it? Well, my friend, 1998 happens to be the year that the “Homerun Record Chase” captured the hearts of Americans everywhere. McGwire vs. Sosa, it was a beautiful thing. And great for baseball too, wasn’t it, Bud? Almost made me forget about all that nastiness back in ‘94. Instead of players banding together against the MLB owners, they’re back to ripping each other’s heads off in the batter’s box, all amped up on er… competition. What baseball strike? 70 HR’s! You must have been so relieved.

Now Mr. Commissioner, I’d like to tell you a story about our friend, little Bobby Spitball. One day little Bobby begins to notice that all his friends are looking kinda “different”. All of a sudden Barry B. has got a neck the size of a rabid pit-bull, and the bulging veins to boot! And Sammy S. from down the block has come down with a bad case of ass pimples. And what’s more, they’re knocking them out of the park. With his friends all talking like sopranos on helium, and taking a “swing-for-the-fences” approach, little Bobby has a choice to make. He can either keep doing what he’s doing but do it in the minor leagues, or he can unleash everything he’s got. So little Bobby thinks to himself “I’ll either strike him out, or kill the guy sitting 5 rows behind home plate”. Take a look at the results…

clip_image006

*Tear* there goes little Bobby’s rotator cuff. If only there was something he could take…

clip_image008

So much for the art of the complete game! (Someone please notify Dusty Baker!)…

So what does this mean to fantasy baseball? Quite a bit, depending on your league’s stat categories. First of all, this season could be the beginning of a trend, as numbers begin to compensate in what is hopefully the post-steroids era. Last year was a major “down” year for homeruns, producing the lowest homerun totals in a decade. Maybe a sign that power-hitting is beginning to normalize. The number of 20-HR players has remained fairly constant the last couple years, but the number of players that hit 32+ HR’s has dropped drastically from 32 to 16. 40+ HR hitters have dropped from 11 to 5. The performance curve for homeruns has flattened out. While the majority of starting batters in most fantasy leagues will still hit 15+ to 20+ HR’s, with most players topping out below 32 HR’s, there will be fewer of them hitting 35+ HR’s, and chances are you will have just one of them. So… with so few of them, does that make top HR hitters more valuable?

In a way, sure, having A-Rod or Prince Fielder last year would’ve given you one of only two 50-HR guys. But this year you will be paying a premium for HR’s in the draft. My feeling for the upcoming season is that HR-hitting as a stat category has to be devalued a little bit, at least in Head-to-Head leagues. The homerun-hitting field has evened out, and except for a lucky few owners, most teams will hover around the same homerun totals.

The days of building your team around HR’s is over. We’ve gotten used to the power-hitting of the last 5-10 years, when having a team full of big boppers guaranteed a consistent stream of HR’s that could take you to the championship. Well, guess what? Homeruns are hard to hit! Especially without HGH! These days, it really is a “feast or famine” stat category. And unless your team has more than two or three 30+HR guys, you don’t have enough of a safety net to even out the performance peaks and valleys from week to week. Bottom-line, sticking to the slugging strategy this year is going to be a major crapshoot, and I just don’t think it’s going to pay off. Most of us will have to learn to suffer through the HR peaks and valleys and adapt accordingly to winning or losing that category in cycles. Even if you invest your top resources in accumulating high HR’s and are lucky enough to get good returns on your HR investment, every A-Rod and Prince Fielder sometimes go a week without hitting a homerun. And you better hope it’s not during the playoffs.

In pondering the HR issue, I’ve also realized how impossible it is to predict HR’s this year. I’m calling it the “20/40 rule”. Would you be surprised if Manny Ramirez hit 20 HR’s? I wouldn’t, in fact that’s what he hit last year. Would you be surprised if he hit 40 HR’s? I wouldn’t, he hit 45 just a few years ago. I feel this way about many of the good players out there. I wouldn’t be surprised if they hit 20 or 40 HR’s. I find that crazy! Well, that’s what happens when baseballs aren’t getting slammed hundreds of feet over the fences. As batting performance becomes more realistic, we will begin to notice once again that sometimes there’s almost no difference between a double and a homerun other than sheer luck…

I think we have successfully reflected this attitude and strategy in our drafting tool. Based on last year’s stats, you can only worry about homeruns so much this season, and nothing’s guaranteed. We’re not saying not to draft big homerun hitters, you still have to do that to compete. Just don’t stretch further for one-dimensional HR hitters because you think the decrease in power-hitting means you have to overspend. It’s the same with complete games and shutouts, if your league uses those categories. With the trends we’re seeing, complete games are becoming increasingly rare and random. You couldn’t even chase them if you tried… But you could overpay for them.

So Back to you Mr. Commissioner… What can explain these drastic changes in statistical numbers? Well, I can’t pretend to know anything about standing in the box and trying to actually swing a round bat at a round ball, while trying to hit it square. But I think I’ve come up with an explanation which will please everyone.

It’s the baggy uniforms. Really it is, check this out…

Look at former All-Star, NL MVP, and Silver Slugger Keith Hernandez:

Yes, it’s a tight uniform, and it’s also worth about 12 homeruns a season. The year McGwire stumbled into his 49-homerun rookie season, was the year Keith Hernandez hit his career high 18 homeruns.

Or look at former 15-time All Star, Silver Slugger, NLCS MVP, and 2002 Hall of Fame Inductee Ozzie Smith:

…and of course, there’s Barry
