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)

Mets trade Curtis Granderson to the Dodgers

The Mets traded centerfielder Curtis Granderson to the Dodgers for cash considerations or a player to be named later, the teams announced late Friday night. Granderson was rumored to be drawing interest from teams earlier in the week, and found a landing place after slashing .256/.360/.721 since the start of the month. In a corresponding move, the Dodgers designated right-hander Dylan Floro for assignment to clear roster space for the outfielder.

As a whole, the 36-year-old’s 2017 campaign has been a tad underwhelming. Granderson entered Saturday batting .228/.334/.481 with 19 home runs and an .815 OPS through 395 PA, and accrued 1.7 fWAR to the 5.1 fWAR he produced during his pennant-winning, MVP-contending season in 2015. Still, with under $4 million remaining on his contract, another 20+ homer season around the corner and the defensive chops to man center field, it looks like a prudent deal for the Dodgers as they continue to bulldoze their way to the playoffs this fall.

The club has yet to outline their plans for Granderson, but his addition to a crowded outfield could displace centerfielder Joc Pederson, who turned in a meager .214/.329/.415 batting line through 292 PA in 2017. It could also have ramifications for fellow veteran Andre Ethier, assuming he’s healthy enough to compete for a starting role when he comes off the 60-day disabled list in September. The Mets, meanwhile, are expected to lean more heavily on rookie outfielder Brandon Nimmo, who’s made just five starts this season after struggling to get consistent playing time on the field.

Corey Kluber exits game with right ankle sprain

Indians’ right-hander Corey Kluber was removed from the sixth inning of his start on Friday night, bringing a streak of 14 starts with 8+ strikeouts to an unfortunate end after he sprained his right ankle. Kluber stumbled off the mound while trying to field a base hit from Eric Hosmer and was seen visibly limping as he moved to cover first base. He was allowed to stay in the game for one more batter, but quickly yielded a three-pitch single to Melky Cabrera and left the mound with head athletic trainer James Quinlan.

It was a poor ending to another strong outing by the right-hander, who delivered 5 1/3 innings of one-run, four-strikeout ball and took his 12th win of the season after the Indians amassed a nine-run lead. Postgame comments by Cleveland skipper Terry Francona suggest that Kluber isn’t facing a serious setback after sustaining the sprain, however, and might even be good to go by the time his next start comes around on Wednesday.

While the Royals escaped Friday’s loss without injury, the 10-1 drubbing pushed them 6.5 games back of the division lead and half a game behind the Twins and Angels for the second AL wild card berth. They’ll host a rematch on Saturday at 7:15 ET, with left-hander Jason Vargas set to face off against Indians’ righty Trevor Bauer.
