FanGraphs and Baseball Reference agree on a value for replacement level in WAR

23 Comments

When we talk about WAR, we’ve historically been talking about two different metrics, actually. Because the two entities which developed and calculate WAR — FanGraphs and Baseball-Reference.com — have historically used two different values to determine the “replacement level” component of the stat.

While those of you who dig into these metrics with anything beyond a passing glance were aware of and made accommodations for this, it led to at least some confusion among more casual observers and led to a lot of potshots from the fans and the press looking to take issue with any stat more complicated than batting average. “Hey, why should we care about WAR if you guys can’t even agree what it is,” they would say, prior to coming up with some Edwin Starr/”what is it good for” bon mot which they believe to be original and clever.

Now, however: a grand agreement. From Dave Cameron:

You can calculate replacement level a number of different ways, but in the end, it always leads back to a number in this vicinity. Baseball-Reference arrived at a number a little higher than what Tango had used, while we came up with one a little lower. Because they were at opposite ends of the defensible spectrum, the different baselines gave a false sense of difference in the actual calculations. Now, with an agreed upon replacement level, those differences that are solely due to scale will go away.

There will still be some subtle differences in the ultimate calculation (read Dave’s post for more information on that) but now one big difference is gone, which should lead to a bit more harmony and less unnecessary strife when it comes to this stuff.

I’m sure some people will still take pot shots “Hey, if it’s so good, why do you have to tinker with it all the time!” they will claim, ignorant of how math and science work, but this is a good move.

(why the Mike Trout pic? Eh, didn’t want to use the calculator for two posts in a row)

Dodgers plan to tab Clayton Kershaw for Game 1 of World Series

MLB.com’s Ken Gurnick reports that the Dodgers plan to tab ace Clayton Kershaw for Game 1 of the World Series. Nothing is set in stone yet ahead of Tuesday’s Game 1 of the World Series. In the event Kershaw can’t start Game 1, Rich Hill would start. Otherwise, Hill would start Game 4.

Kershaw, started Game 1 and Game 5 of the NLCS against the Brewers, then closed out Game 7 with a flawless inning. He was hit around to the tune of five runs (four earned) over three-plus innings in Game 1, but rebounded for seven innings of one-run ball in Game 5. He struck out two en route to sending the Dodgers to the World Series in the ninth inning of Game 7.

Kershaw also tossed eight shutout innings against the Braves in Game 2 of the NLDS. Overall, he has a 2.37 ERA in 19 innings this postseason. There was no doubt who would be the Dodgers’ first choice to start Game 1, but it’s a relatively recent situation where the ace of a team also closed out the final game of the previous series.

Hill has put up a 2.61 ERA in 10 1/3 innings this postseason. While he doesn’t have Kershaw’s pedigree, the Dodgers would be confident having him lead off the series. Hill was excellent down the stretch last year, helping the Dodgers reach Game 7 of the World Series against the Astros.

The Red Sox plan to start Chris Sale in Game 1 now that he’s recovered from a brief stint in the hospital due to a stomach ailment. The lefty has a 3.48 in 10 1/3 innings in the playoffs this year. He’s among a handful of candidates for the AL Cy Young award after posting a 2.11 ERA in the regular season, but his lack of innings (158) may hurt him.
