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

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)

Report: Yankees, Reds finalizing trade for Sonny Gray

Barring physicals and roster reshuffling, the Yankees and Reds are all but ready to finalize a deal involving right-hander Sonny Gray, Fancred’s Jon Heyman reported Saturday. The exact return has not been confirmed, but Heyman hears that the Yankees will receive top infield prospect Shed Long and a draft pick in exchange for Gray, with an as-yet unnamed third player possibly involved as well.

According to several reports earlier in the day, negotiations came down to the wire as the Yankees first had their eye on the Reds’ no. 6 prospect, 22-year-old catcher Tyler Stephenson. The Reds ultimately elected to hang on to Stephenson and send Long to New York, as they currently have a greater need for catching depth and weren’t expected to be able to provide a full-time role for the infielder in 2019. Long, 23, is ranked seventh in the Reds’ system and appears to be nearing his MLB debut after batting .261/.353/.412 with 12 homers and a .765 OPS across 522 PA at Double-A Pensacola last year.

Gray figures to step into a prominent role within the Reds’ rotation, which is likely to be a mix of recently-acquired left-hander Alex Wood and right-handers Tanner Roark, Luis Castillo, Anthony DeSclafani, and Tyler Mahle, among several others. Despite Gray’s struggle to remain productive on the mound — he’s three years removed from his only All-Star campaign and turned in a disappointing 4.90 ERA and 2.16 SO/BB rate in 2018 — he might yet help stabilize a team that trotted out the fifth-worst rotation in the majors last season. If, on the other hand, the veteran righty finds the hitter-friendly confines of Great American Ball Park a little too unforgiving this year, the Reds can take some comfort in the fact that he’s due to enter free agency in 2020.
