Sean Forman: WAR is “GDP for baseball”

23 Comments

There was some big news in the baseball stats community recently, as Baseball Reference and FanGraphs agreed to a common replacement level in their Wins Above Replacement statistic. Though the two sites’ computation of the statistic still differs in other ways, creating some uniformity in replacement level should clear up some of the confusion around the stat among casual observers.

Sean Forman, the creator of Baseball Reference, responded to some general criticisms of WAR yesterday. Most notably, he referred to WAR as “GDP for baseball”. GDP, of course, stands for Gross Domestic Product, an estimate of the market value of a country’s goods and services. WAR often gets tossed aside because it’s complicated, requires a lot of steps to calculate correctly, and is a single number that covers broad subject matter, but Forman shows how those criticisms are not levied against GDP despite being very similar in nature. If you trust GDP, you should trust WAR.

Diamondbacks place Shelby Miller on the 10-day disabled list

Leave a comment

The Diamondbacks announced on Monday that starter Shelby Miller has been placed on the 10-day disabled list with right elbow inflammation. Miller will get a second opinion on his elbow on Tuesday, per MLB.com’s Steve Gilbert. Pitcher Silvino Bracho has been called up from Triple-A Reno to take Miller’s spot on the roster.

Miller, 26, left Sunday’s start with what was described at the time as forearm tightness. Through his first four starts, Miller is carrying a 4.09 ERA with a 20/12 K/BB ratio in 22 innings.

Bracho, 24, has pitched quite well in 6 2/3 innings of relief at Reno. He’s given up just one unearned run on four hits and a walk (intentional) with 12 strikeouts.

Archie Bradley figures to take Miller’s spot in the starting rotation as Bracho will work middle relief.

And John Lackey is livid.

The Brewers’ first baseman homered in each of his first two plate appearances against Reds starter Amir Garrett on Monday evening, helping his team to a 6-1 lead after two frames. The first was a solo blast in the first inning, and the second was a two-run shot to the opposite field in the second inning.

According to MLB.com’s Adam McCalvy, Thames has tied the Brewers’ record for home runs in April with 10. Carlos Lee also hit 10 homers in April 2006.

Seven of Thames’ 10 home runs have come against the Reds. Including his first two at-bats on Monday night, Thames is hitting .379/.474/.924 with 17 RBI along with the 10 dingers. Not too shabby from a guy the Brewers signed to a three-year, $16 million contract during the offseason.

Lackey and Cubs pitching coach Chris Bosio both recently implied Thames is using performance-enhancing drugs, but Thames was tested immediately after last Monday’s game against the Cubs.
