Base Runs and Carl Hubbellby Dave StudemanJune 19, 2008 Base RunsSome years ago, the big focus in baseball analysis and sabermetrics was the development of "run estimation" calculations that estimated the number of runs produced by individual players for their teams. In the 1980's, two competing approaches emerged in the general mindset of people who cared about such things: Bill James' Runs Created and Pete Palmer's Linear Weights, also known as Batting Runs (scroll down the linked page for the Batting Runs definition). Today, Baseball Reference lists both stats in the "Special Batting" section of their player pages. Here's an example, partway down the page. Since then, many people have derived their own run estimation formulas. Dan Fox covered most of them in this space a few years ago and John Jarvis has also posted a detailed study of various formulas. The Internet's resident expert on run estimation formulas may well be the analyst known as US Patriot. Here's a recent example of his work. In my humble opinion ("IMHO" to you text messengers), the best overview of run estimation formulas was a three-part series posted by Tangotiger at BBTF (and now available on his site): Part One Part Two Part Three One of the main lessons I took from Tango's articles was that context truly matters. In a world in which every batter hit a homer, each one would be worth exactly one run because no one would ever be on base. Conversely, in a world in which every batter walked, each walk would also be worth exactly one run. Of course, we don't know of any worlds like that, at least not on the professional level. But analyses such as Dan's and John's posted above, which depend on comparisons with team statistics, can be misleading. Why? Because the difference between the best and worst offensive teams is much less than the difference between the best and worst offensive players. Albert Pujols may not be as extremely different from Tony Pena, for instance, as the world in which everyone hits a home run all the time. But they are very, very different. And the results of team-based analyses may not apply to them at all. So Tango makes a pretty compelling argument that Base Runs (invented by David Smyth) is the best run estimator available, based on two things:
Now, Bill likes to be flip in his answers, so I'm not sure we should interpret his response too specifically. But in case there is any question, I'm convinced. In fact, I venture to say that most THT writers who've spent much time thinking about the issue are convinced. Up to now, we have reported Runs Created in our stats section for three basic reasons:
Here's one reason. If you add up all the Base Runs of all players this so far this year, you get 9,686 runs. If you add up all of their Runs Created (before the final step, in which you force the RC totals to equal team totals), you get 9,906 runs. The actual major league total for runs scored as of Wednesday? 9,693. Base Runs comes within seven runs of the total; Runs Created is more than 200 runs greater. In the Win Shares system, James forces the RC totals for all players to equal the team totals by applying a proportionate ratio. In other words, the system applies an arbitrary approach to make the numbers "foot." Once I apply Base Runs to Win Shares, that step won't really be necessary. By definition (and through a more logical approach), the Base Runs figures will virtually foot with all the team totals. To give you a sense of the difference between the two estimators, here is a comparison of the top ten batters in Base Runs and their Runs Created totals (through Tuesday's games. See my note below regarding this version of Base Runs). Player Team BR RC Diff Berkman, Lance HOU 64 67 -3 Utley, Chase PHI 62 61 1 Burrell, Pat PHI 59 59 0 Hamilton, Josh H TEX 58 56 2 McLouth, Nate PIT 58 59 -1 Kinsler, Ian M TEX 57 55 2 Jones, Chipper ATL 57 65 -8 Sizemore, Grady CLE 56 56 0 Gonzalez, Adrian SD 55 60 -5 Bradley, Milton TEX 54 53 1As you can see, there usually isn't much of a difference between RC and BR for most batters, but there are some significant differences for a few individual batters, particularly Chipper Jones and Milton Bradley. So Base Runs is better, and it can make a difference for some individual players. It's time to switch. If you're not convinced, post a comment at Ballhype and I'll follow up with some more analysis of the two systems. In the meantime, I'll post a note to THT Live once we have Base Runs in production. Carl HubbellTHT reader Warren Corbett is working on a book about the life and times of Paul Richards, which promises to be an extremely interesting read. Richards was one of the most innovative figures in baseball history. While conducting his research, Warren came across something that has never been published before: a 1982 oral interview with Carl Hubbell, the great Giant screwballer. (I know that sounds funny. Let's see what my editors think.) The interview had been conducted by SABR's Oral History committee, which loaned it to the Baseball Hall of Fame and only recently got it back. Here's the interview, with a little introduction by Warren. I thought you'd find this interesting, particularly after reading Mike Fast's recent article about Daniel Herrera's scroogie. Carl Hubbell was retired after 253 major-league victories and many years as the Giants’ farm director when author Walter Langford interviewed him in 1982, a week before his seventy-ninth birthday. The tape is in the collection of SABR’s Oral History Committee. After Hubbell graduated from high school in Meeker, Oklahoma, he went to work in the oil fields and pitched for company teams. He began his professional career in 1923 at age 19, with Cushing in the Oklahoma State League. When the Class D league folded the next year, he moved to Ardmore of the Western Association and Oklahoma City of the Class A Western League. That’s when his life changed: I think probably one of the most fortunate things in my life was, there was an old lefthanded pitcher on the ball club named Lefty Thomas (short-term major leaguer Claude Thomas)…Really knew how to pitch, and for some reason or other he really attracted me. He was the only one I ever looked at. He made pitching look easy, and he had a kind of a sinking fastball. Of course the righthanded hitters like to tee off on the lefthander, especially when they get him in a hole. And he’d go out there and got one or two on, and he’d just throw that sinker on the outside corner to get a three-hopper to shortstop, boom-boom. He’d walk off, wouldn’t break a sweat or anything. And, boy, it just enthralled me. I guess I had the instincts of knowing – I was real young – and to know that was the one, right there. Great stuff. I particularly like the comments about John McGraw and Hubbell's observation that "the real effectiveness of the screwball was not the break at all. It’s the speed of the ball." Many thanks to Warren Corbett, and be sure to watch for his book on Paul Richards. References and Resources Base Runs is a very flexible formula and can be implemented in a number of ways. In order to facilitate a comparison with the most recent version of Runs Created, I calculated it in the followings ways:
