Welcome to the 2013 Doug Slaten Awards!
Two years ago, now-ex-Nat Doug Slaten allowed 13 inherited runners to score in just 16.2 IP, which prompted me to develop this stat I call "earned Earned Run Average" (or eERA). Whenever an inherited runner is allowed to score, eERA shifts part of that earned run from the pitcher who first put that runner on base to the pitcher who allowed him to score. For more details on the math and such, see the inaugural 2011 fanpost.
This year the Nationals bullpen slatened* 42 runs (up 1 from 2012, but way down from the 76 runs slatened in 2011). The bullpen struggled over the course of the season, with lots of new blood showing up in the second half.
* slaten, verb : the act of a pitcher allowing a runner to score without affecting his own ERA thanks to the rule that counts earned runs against the pitcher who first allowed that runner to get on base

With so many contenders, how do we pick a winner this year? Stammen slatened more often than anybody this year, but he also pitched a whole lot of innings. Xavier Cedeno is the pitcher whose adjusted ERA is 77% higher than the original, but he only pitched 6 innings and only allowed one of six inherited runners to score. Tanner Roark certainly struggled as a reliever, but it is clear from his record that he certainly does not deserve this kind of award.
That leaves us with a choice between Fernando Abad and Ian Krol. Each of them slatened six runs this year, but though I wish I could give them both a share of the prize, Abad did pitch ten more innings than Krol.
The 2013 Doug Slaten Award goes to Ian Krol. His eERA of 5.03 is a subtle hint that he was not performing even adequately on the mound this year. None of the inherited runners he allowed to score came to him with no outs. The odds were always slightly in his favor, but he found ways to blow it. His failure to pick up his teammates added a whole run to his barely acceptable rookie ERA. As a rookie, should he be given a second chance, or should he go the way of Slaten and Burnett?
Yes, this is the third year in a row that a lefty specialist has taken the prize. I hope Mr. Rizzo is paying attention.
As I mentioned last year, in 2012 only 4 Nats pitchers had an eERA over 4.00. Unfortunately, they were not able to repeat in this regard. A total of nine pitchers in 2013 had an eERA above 4.00, and they pitched a total of 210 innings. The four least used of these pitchers did not finish the season on the Nationals roster.
Positive note for the year - Taylor Jordan got slatened three times, and his adjusted ERA is a solid 3.31. Here are the eERAs of returning potential starters for next season (by IP): 3.11, 3.22, 2.98, 3.84, 3.55, 1.91, 3.31 - an overall average of 3.14!
