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)

Adam Eaton sustains leg injury after tripping over first base

Nationals’ outfielder Adam Eaton was carried off the field after stumbling over first base on Friday night. In the ninth inning of the Nationals’ 7-5 loss to the Mets, Eaton appeared to catch his ankle on the bag as he ran out an infield single, suffering a leg injury on the fall. He was unable to put pressure on his left leg after the play and required assistance by two of the Nationals’ athletic trainers as he exited the field.

Eaton is scheduled to undergo an MRI on Saturday, but Nationals’ manager Dusty Baker told reporters that it “doesn’t look too good.” It’s the first significant leg injury the outfielder has sustained since 2014, when he went on the 15-day disabled list with a hamstring strain. He’ll likely be replaced by Michael Taylor in center field for the next couple of games, though that could be a temporary fix as the Nationals seek a better solution during Eaton’s recovery process.

Madison Bumgarner likely sidelined through the All-Star break

It’s been just over a week since Giants’ left-hander Madison Bumgarner got a serious scare after a nasty dirt bike accident. He escaped with bruised ribs and a Grade 2 strain of his left shoulder AC joint, but there was some speculation that the injuries would cause a significant, if not permanent, setback in the southpaw’s career. Thankfully, things aren’t looking quite so bleak today. Not only will Bumgarner not require surgery, but he could return as soon as the week following the All-Star break, the Giants said Friday.

Of course, that timeline is wholly dependent on how smoothly the recovery process goes, so nothing is set in stone yet. NBC Sports Bay Area’s Alex Pavlovic estimates 2-3 months of rest and rehab, including “two months before he can get back on the mound and then another three to four weeks of throwing and rehab starts before he’s big league-ready.” It’s a long and laborious schedule, but still looks much better than any surgical alternative.

Prior to the accident, Bumgarner was working on a solid start to the 2017 season. He maintained a 3.00 ERA, 1.3 BB/9 and 9.3 SO/9 through 27 innings with the club, though his average 1.75 runs of support per start fed into an 0-3 record.
