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)

Enrique Hernandez’s performance one for the record books

Entering Thursday’s NLCS Game 5, Dodgers outfielder Enrique Hernandez had never hit a home run nor even driven in a run in the playoffs in his four-year career. He had homered twice in a regular season game just twice and his career-high for RBI in a game was four.

Hernandez hit three home runs and knocked in seven runs to help power the Dodgers past the Cubs 11-1 to win the National League pennant and punch their ticket to the World Series. His first homer was a solo homer to center field in the second inning off of starter Jose Quintana. He blasted a grand slam to right field off of Hector Rondon in the fourth, then tacked on a two-run blast in the ninth inning off of Mike Montgomery to make it 11-1.

Hernandez is the 10th player to hit three home runs in a postseason game. Jose Altuve, of course, did it two weeks ago in Game 1 of the ALDS against the Red Sox. Before Altuve, Pablo Sandoval (2012), Albert Pujols (2011), and Adrian Beltre (2011) were the last players to accomplish the feat.

Hernandez’s seven RBI set a new National League record for a postseason game. Only four other players — Troy O’Leary, John Valentin, Mo Vaughn, and Edgar Martinez — accomplished the feat.

No one has hit three home runs and knocked in seven-plus in a game… until Hernandez. He certainly picked a good time to break out.
