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)

Angels’ Pujols has foot surgery, could be sidelined 4 months

ANAHEIM, Calif. — Los Angeles Angels slugger Albert Pujols had surgery on his right foot Friday, possibly sidelining him past opening day.

Angels general manager Billy Eppler said Pujols had the procedure Friday in North Carolina to release his plantar fascia, the ligament connecting the heel to the toes. The three-time NL MVP was bothered by plantar fasciitis repeatedly during the season, but played through the pain in arguably the strongest year of his half-decade with the Angels.

Eppler said the surgery typically prevents players from participating in baseball activities for three months, along with another month before they’re ready to resume playing in games. Opening day for Los Angeles is April 3, and the Angels hope Pujols can be ready.

“He’s at that point in his career where he’s keenly aware of what’s happening with his body,” Eppler said in a phone interview. “I don’t put the timetable on Albert like you would with your younger players. We’ll just see in Albert’s case, as he progresses, what his timetable is.”

Pujols, who turns 37 next month, batted .268 last year with 31 homers and 119 RBIs, the fourth-most in the majors – although his .780 OPS was among the worst of his career. He largely served as a designated hitter instead of playing first base due to problems with his hamstrings and feet.

Pujols heads into 2017 with 591 career homers, ranking him ninth in major league history. He is 18 homers behind Sammy Sosa for eighth place.

After playing in pain until the final week of the Angels’ disappointing season, Pujols began shock wave therapy on his foot early in the offseason, believing he wouldn’t need surgery.

But Pujols’ foot became more painful in recent weeks despite the therapy, and he huddled with the Angels’ top brass to decide on surgery after his most recent trip to see Dr. Robert Anderson in North Carolina. Continuing with conservative care would have required 10 more weeks, forcing Pujols to miss the first half of the 2017 season if he still required surgery.

“He just felt that the pain had gotten to a point where he was comfortable” having surgery, Eppler said. “If we did delay it, you’re just looking at 2 1/2 more months into the season.”

Pujols had a different type of surgery on his right foot last winter, but recovered in time for opening day. He also had plantar fasciitis in his left foot during the 2013 season, eventually forcing him out for the year when his fascia snapped.

Pujols has five years and $140 million remaining on the 10-year, $240 million free-agent contract that pried him out of St. Louis, where he won two World Series and became a nine-time NL All-Star.

The Angels haven’t won a playoff game since Pujols’ arrival and Mike Trout‘s concurrent emergence as one of baseball’s best players. They went 74-88 last season, the injury-plagued club’s worst record since 1999.

According to an official announcement, the Diamondbacks have acquired former Pirates quantitative analyst Mike Fitzgerald as their new Director of Research and Development.

Fitzgerald joined the Pirates’ front office in 2012, where he frequently accompanied the team on the road to help breach the divide between analytics and the clubhouse. According to a profile written by Grantland’s Ben Lindbergh in 2014, Fitzgerald’s multifaceted approach brought balance and perspective to the organization, whether he was assisting coaches in making statistically sound decisions, optimizing the batting order, weighing in on scouting and personnel decisions, developing more effective defensive positioning, or keeping players and personnel appraised of the latest developments in sabermetrics.

In the wake of Fitzgerald’s departure, Pirates’ GM Neal Huntington praised the Diamondbacks for a smart acquisition and said that the club has every intention of finding a replacement analyst, albeit one who will have some big shoes to fill.
