Putting WAR in Context: A Response to Bill James

Nine years ago next month, we introduced a new stat to the pages of FanGraphs. We called it Win Values, and on the player pages and leaderboards, it went by the acronym WAR. We wouldn’t actually start calling it that, or use the words for which the acronym stood (Wins Above Replacement) for a little while, since we thought Win Values sounded cooler. And as the people who bring you WPA/LI and RE24, we’re clearly the experts on statistical naming coolness.

Over the last nine years, WAR has become something of a flagship metric, not just for us, but for the analytical community at large. Baseball-Reference introduced their own version, while Baseball Prospectus modernized their version of WARP — their version adds the word player to the name, thus the P — to provide something that scaled a bit more like what was presented here and at B-R. Because WAR is a framework for combining a number of different metrics into a single-value stat, there are also quite a few other versions of WAR out there, each with their own calculations.

But while everyone uses different inputs — and therefore arrives at slightly different results — almost all of the regularly updated WAR metrics are built on some version of linear weights, which assigns an average run value to each event in which a player is involved, regardless of what actually happened on the play. If you hit a single, you get credit for hitting a single. It’s worth some fraction of a run, regardless of whether you hit it with two outs and the bases empty in a the first inning of an eventual blowout, or whether it was a walk-off two-run single to give your team the lead. In most versions of WAR, the value of a player’s contribution is calculated independent of the situation in which it occurred.

Bill James is not a fan of that decision.

We come, then, to the present moment, at which some of my friends and colleagues wish to argue that Aaron Judge is basically even with Jose Altuve, and might reasonably have been the Most Valuable Player. It’s nonsense. Aaron Judge was nowhere near as valuable as Jose Altuve. Why? Because he didn’t do nearly as much to win games for his team as Altuve did. It is NOT close. The belief that it is close is fueled by bad statistical analysis—not as bad as the 1974 statistical analysis, I grant, but flawed nonetheless. It is based essentially on a misleading statistic, which is WAR. Baseball-Reference WAR shows the little guy at 8.3, and the big guy at 8.1. But in reality, they are nowhere near that close. I am not saying that WAR is a bad statistic or a useless statistic, but it is not a perfect statistic, and in this particular case it is just dead wrong. It is dead wrong because the creators of that statistic have severed the connection between performance statistics and wins, thus undermining their analysis.

James strongly believes that the metric falls apart by building up from runs, rather than working backwards from wins, since the context-neutral nature of the metric means that what WAR estimates a group of players are worth won’t add up to how many wins their team actually won. In his mind, the decision to make WAR context-neutral isn’t a point on which reasonable people can disagree; it’s just a mistake.

Sunday Notes: Mike Rizzo and the Nats’ Analytical Wavelength

When I talked to Mike Rizzo in Orlando earlier this week, he told me the Washington Nationals have an eight-person analytics department that includes “three or four employees” who have been added in the last two years. The veteran GM also told me they have their own “Scouting Solutions, which (they) call The Pentagon.” In Rizzo’s opinion, his team has gone from behind the times to having “some of the best and brightest analytics people in all of baseball.”

A pair of uniformed-personnel changes further suggest an increased emphasis on analytics. Dave Martinez has replaced Dusty Baker as manager, and Tim Bogar has come on board as the first base coach. According to Rizzo, their saber-savviness played a role in their hirings.

“It was part of the process,” related Rizzo. “Davey is a 16-year major league veteran who can appeal to a clubhouse of major league players — there’s a respect factor there — and he’s also coming from two of the most-analytical organizations in baseball, in Tampa Bay and Chicago. He’s bringing that love of analytics and the implementation of those statistics with his thought process. Read the rest of this entry »


The BBWAA Did A Great Job

Yesterday, the BBWAA announced the last of their major awards for the 2017 season, with Jose Altuve and Giancarlo Stanton taking home the MVP honors for their respective leagues. And while there were certainly more-than-reasonable cases to be made for the runner-up to take the top spot, the overall results of the voting show that the BBWAA is, more than ever, doing a pretty great job in rewarding the right players for their performances.

An Estimate of Every Team’s Payroll Room

Scott Boras’s life is currently populated by buses to Playoffville, a mythical creature named J.D. Kong, and squirrels in trees with nuts. It’s time, in other words, for teams to get out the checkbook and start paying his clients.

How much those teams can spend will become more clear over the coming weeks. But we can estimate now. By looking at how much every team has on the books currently, it’s possible to identify those teams in the best position to make major moves, either by taking on a contract like Giancarlo Stanton’s or signing a big-name free agent such as Jake Arrieta, Yu Darvish, Eric Hosmer, or J.D. Martinez.

Last winter, there was considerable uncertainty with regard to spending, as the new CBA hadn’t yet been formalized. The players and the owners eventually reached an agreement, and while the implications of that agreement have yet to be fully fleshed out, we have a greater understanding of its effects than we did last year at this time. Teams know how much they can expect to pay and receive in revenue sharing. Big-market teams, meanwhile, have a much better idea of how much they might have to pay in taxes with competitive-balance tax amounts and penalties all spelled out. That could lead to a little more spending this winter than we saw last offseason, but teams could also be saving up for next year’s superior free-agent class, trying to avoid some tax penalties, or simply rebuilding.

To start, let’s take a look at current payroll commitments as teams start to spend more for next season. The chart below depicts a combination of guaranteed salaries and estimated arbitration salaries for each club — plus whatever extra payroll would be required at the league minimum to create a full roster. Data care of Cot’s Contracts.

The figures we see here aren’t all that surprising. The big-money Dodgers, Giants, Nationals, Red Sox, and Yankees lead the way. Way down at the other end we find the the lower-revenue Athletics, Brewers, Padres, and Rays along with the rebuilding Chicago White Sox and the Philadelphia Phillies, the latter having committed less than one-fifth the amount of the Los Angeles Dodgers.

Giancarlo Stanton Named NL MVP

Giancarlo Stanton is your 2017 NL MVP. Barely.

The Marlins outfielder edged out Cincinnati’s Joey Votto by two points (two!), for a final total of 302 to 300. Votto and Stanton each received 10 first-place votes. The latter, however, received 10 second-place votes; the former, just nine. The individual ballots are here.

According to the BBWAA, there have been only two closer NL MVP races than the 2017 edition: in 1979, when Keith Hernandez and Willie Stargell tied and, in 1944, when Cardinals shortstop Marty Marion topped Cubs outfielder Bill Nicholson by a single point.

You could pick either Votto and Stanton and not err egregiously. Paul Goldschmidt was the third NL MVP finalist. Despite producing an excellent season in his own right, he was a cut below by most measures.

The voters selected Stanton. They recognized a fine player, the preeminent home-run artist in the year of the home run. If I had a vote (I did not), I would have placed Votto on the No. 1 line.

Stanton led the majors in home runs (59). If RBIs are your thing, he led the majors there, too (132). He closed off his stance and made real gains in contact and zone discipline. He was more than just a slugger.

Also in Stanton’s favor is the level of his opponents. He faced a slightly higher quality of competition according to Baseball Prospectus’ Quality of Pitchers Faced metric, holding a 107 to 103 edge.

Corey Kluber Rides Historic Pitch to Second Cy Young Award

What’s so remarkable about Corey Kluber’s second Cy Young Award, the receipt of which was announced Wednesday evening, is he won it despite missing a month of the season. At the All-Star break, it looked like Sale in a runaway, but Kluber found another level and produced one of the great Cy Young comebacks of all-time. That’s how dominant he was from the point at which he returned in June through the end of September following a trip to the DL with a back strain.

How good was Kluber?

Starting with that appearance against Oakland on June 1, Kluber struck out 224 batters (!). That’s 224 strikeouts in two-thirds of a season. That’s 224 strikeouts against 619 batters faced, good for an astounding 36.2% rate. He walked only 3.7% of those same batters.

The difference between Kluber’s strikeout and walk rate (K-BB%) from June to September was 32.5 points. To put that mark in context, consider: among all pitchers, only elite bullpen arms recorded Craig Kimbrel, Kenley Jansen and Chad Green better marks for the season. (It should be noted that Chris Sale led MLB starters over the whole season with a 31.1-point differential. Kluber finished second to Sale among starters, with a 29.5-point mark.)

The Winter’s First Trade Shows How the Game Is Changing

If you had Jerry Dipoto in the pool of which GM will make this off-season’s first trade, congratulations, you win nothing because of course he did. Trader Jerry is baseball’s version of the red paperclip guy, attempting to take his team from mediocrity to contention by making a million small upgrades. And his latest deal is particularly interesting, even if it wasn’t exactly a swap of household names.

The deal’s particulars.

Seattle Gets:

Ryon Healy, 1B

Oakland Gets:

Emilio Pagan, RHP
Alexander Campos, SS

Death, Taxes, and the Orioles’ Need for Starting Pitching

Free agency began a week ago to an expected lack of fanfare. Unlike the NBA, where free-agent deals are often announced minutes after the midnight opening bell, it usually takes a little while for baseball’s hot stove to ignite. Until the GM Meetings, which began this past Monday, free agency is usually dominated by leaked contract demands, contract extensions, and declarations by certain players that they intend to keep playing.

Thus far, the 2017-2018 offseason is no exception. For the moment, we must content ourselves with news of minor-league deals for Kevin Quackenbush and Rubby de la Rosa with Cincinnati and Arizona, respectively.

Alongside the minor-league signings and contract demands, the early days of this offseason have been marked by another annual tradition. According to Orioles beat writer Rock Kubatko, Baltimore has shown “definite” interest in Andrew Cashner and Jason Vargas. The Orioles’ rotation remains a weakness for the club, and as is often the case, the team appears to be targeting mid-level innings-eaters. It also appears to be all they’re likely to afford: due to questionable commitments on the payroll, the Orioles will probably find it difficult to pursue many true rotation upgrades to prop open their closing — or perhaps already closed — window.

Projecting the Minor-League Free-Agent Pitchers

Every winter, hundreds of nondescript ballplayers become minor-league free agents. Players are granted minor-league free agency when they’re omitted from a club’s 40-man roster and have also spent at least six years in the minor leagues. In other words, they’re the ones who weren’t good enough to merit a call-up after several years in the minors, and their organizations suspect they lack the potential to be worthy of a 40-man spot.

Some of these players latch on with new organizations; some of them don’t. But regardless, the overwhelming majority never have much big-league success. Carson Cistulli found that only about 1% of minor-league free agents produce at least 0.5 WAR the following season. Minor-league free agents are the absolute bottom of the barrel when it comes to player transactions. But there’s an occasional gem at the bottom of that barrel. It’s not unheard of, at all, for a minor-league free agent to make a major-league impact. A few successful examples of players I highlighted in this space last year:

  • Wilmer Font dominated the PCL by striking out a jaw-dropping 32% of batters as a starter, earning him a role on the deepest pitching staff in baseball. My money’s on him opening 2018 on someone’s big-league squad.
  • Lane Adams recorded 122 plate appearances of above-average production with the Braves, much of that coming as a pinch-hitter.
  • Jacob Turner was a serviceable swingman for the 97-win Nationals in the season’s first half (33.2 innings, 4.28 ERA through June 18th).

Using my KATOH projection system, I identified the pitchers from this year’s minor-league free-agent class who showed glimmers of promise in the minors. Since none of these players have any sort of prospect pedigree anyway, I utilized the stats-only version of KATOH. Based on their minor-league numbers, there’s reason to believe they might be able to help at the big-league level sometime soon. This analysis considers only players who logged at least 200 minor-league batters faced in either 2016 or 2017.

For reference, here is my piece from yesterday on minor-league free-agent hitters.

*****

1. Scott Barlow, RHP

Barlow split time between the Dodgers’ Double-A and Triple-A affiliates this past year, pitching to a stellar 3.29 ERA as a starter. He struck out 28% of opposing batters while walking a reasonable 10%. Barlow’s numbers were decidedly worse in his seven Triple-A appearances, but on the whole, his 2017 campaign was excellent for a 24-year-old starter.

Modern Hall of Fame Ballot: Ted Simmons, Alan Trammell, and (Not) Lou Whitaker

This is the third post covering the Modern Era Ballot for the Hall of Fame. For a look at the pitchers, click here. For the first four hitters, click here. The introduction below might look familiar.

Last week, the Baseball Hall of Fame announced 10 candidates for consideration for the Modern Era ballot, which includes executives and players whose careers took place mainly from 1970 to 1987. This year, the candidates include one non-player, Marvin Miller, and nine players from that era: Steve GarveyTommy JohnDon MattinglyJack MorrisDale MurphyDave ParkerTed SimmonsLuis Tiant and Alan Trammell. Among the player candidates, we have an interesting mix: some who make their claim with a high peak, those who have longevity on their side, and one player with both. Over the course of three posts, I’m examining all the candidates. Today, we’ll cover the two most deserving position players. I’ll also look at one player left off the ballot.

First, a brief word on the rules and procedures of this ballot, which is an updated version of the old Veteran’s Committee. Baseball has been separated into eras, with Early Baseball (1871-1949), Golden Days (1950-1969), Modern Baseball (1970-1987), and Today’s Game (1988-Present). Most players up through 1969 have had their cases considered many times. As a result, during this cycle (2016-2020), the Early Baseball and Golden Days players are scheduled to be evaluated just once, in 2020, with Modern Baseball and Today’s Game receiving consideration every other year from 2016 to -19. There are 16 voting members on the Committee for election, and players must receive 75% of the vote with voting members limited to four votes.
