Pelfrey Out?

Ken Davidoff at On The Mets Beat, writes about Mike Pelfrey and asks the question, is Pelfrey going back to Triple-A?:

Interesting situation developing with Mike Pelfrey, who could be facing some pressure as Orlando Hernandez works his way back from shoulder bursitis. He continues to have trouble in the first inning with a 12.60 ERA and falling behind in the first inning is an ominous statistic for the Mets, who have been outscored this season, 17-12, in that frame. They also are 13-1 when the score first; 6-10 when they don't.

Is it worth it to stick with Pelfrey? Or if Jorge Sosa continues to pitch well, and Hernandez returns next week, is he better off fixing himself at Triple-A New Orleans? Just a conversation starter for this morning (I know it's the afternoon back East, but it's 10:15 a.m. in the Bay Area.)
