During one of the Mets' recent games, Eric Simon suggested that pitchers should be held responsible for unearned runs, not just earned runs:

 A pitcher gets credit for great defense, why not bad defense?

Whether runs are officially recorded "earned" is in the eye of each game's scorekeeper and the weird rules of baseball. By eliminating errors from the equation, RA would be a sort of defense-neutral statistic, as opposed to the defense-independent stats like FIP.

If the preferred nomenclature were RA (R*9/IP) rather than ERA (ER*9/IP), how would the Mets' pitchers fare? 

As a point of reference, the league-average RA in 2011 is 4.30, pretty significantly higher than the league-average 3.92 ERA. Clayton Kershaw, one of the best pitchers in the game this season, has a 2.71 RA and a 2.45 ERA, and Justin Verlander has a  2.67 RA with a 2.44 ERA. In both cases, the RA is still very impressive.

Here's the RA and ERA of each pitcher who's thrown at least 25 innings for the Mets in 2011:

Player RA ERA
Francisco Rodriguez 3.16 3.16
Taylor Buchholz 3.46 3.12
Manny Acosta 3.65 3.16
R.A. Dickey 3.85 3.47
Tim Byrdak 4.32 3.24
Jason Isringhausen 4.44 4.05
Dillon Gee 4.74 4.48
Ryota Igarashi 4.80 4.80
Chris Capuano 4.85 4.63
Bobby Parnell 4.93 4.38
Jon Niese 5.03 4.40
Mike Pelfrey 5.05 4.68
Pedro Beato 5.19 3.86
D.J. Carrasco 5.80 5.40

A few interesting things:

  • Only two pitchers have identical RA and ERA, and both are relievers.
  • R.A. Dickey, appropriately enough, has the best RA of all Mets starting pitchers.
  • Pedro Beato's huge gap between RA and ERA is by far the highest on the team.
