September rotation?

Brandon Morrow is being shut down after his next start.  With him done, Litsch out, and Rzep being (in my mind) generally ineffective, I wonder what the rotation will look like heading into the end of the year.  Marcum, Romero, and Cecil will remain in the rotation for sure, but who will the other two guys be?  I present some names to you for discussion, with a little tiny blurb about why I believe they should or should not be in the rotation, or whether I am indifferent.

Marc Rzepczynski - currently in the rotation, but as I mentioned, generally ineffective.  I'm not into the in-depth sabermetrics, so I'll go with ERA and WHIP here: 6.31 and 1.64.  Lasted 5.2 and struck out 8 against Detroit, so maybe he's adjusting a little bit.  Then again, gave up four runs and five hits while walking five.

Brian Tallet - he's been in the rotation already, so I have to put him here.  Since mostly everyone here agrees he should be released or pitch only when well ahead/behind, I shall say no more.

Brad Mills - ERA doesn't give me confidence at 4.72 (5.28 at the MLB level), but he's been up in the big leagues already and it wouldn't surprise me to see him back up here again.

Robert Ray - currently the owner of a 5.03 ERA.  Even in Vegas, that's not a great sign.

Sean Henn - his other numbers make me wonder why his ERA is only 4.64. 

Other spare parts - this includes players like Zach Jackson and Lance Broadway, who are the definition of depth guys, but could at the least make a spot start or two.

Shawn Hill - has made ten starts in the various levels of the Jays' organization according to FanGraphs, but seems to have struggled a little in his four starts with Vegas: 1-2 with a 4.20 ERA while pitching a combined 15 innings through those four starts.  Wouldn't surprise me to see him up here, though.

Scott Richmond - could happen.  He's pitched well so far in his minor league assignments, but has yet to pitch above the AA level.

Kyle Drabek - won't happen.  From what I've seen, AA prefers to err on the side of caution, so he won't move Drabek up.  Ditto for Zach Stewart.

An ideal situation for me is to DFA Tallet and move Scrabble to the pen.  Marc's been getting shelled out there almost every time out, so an inning or two here and there is a little less for him to look at and figure out what he did right and what he can improve on.  More focus on a smaller sample size might equal a little more success for him.  In that situation, the other two starters would be Mills and Hill.  I like Richmond, but I don't think AA ball is really adequate prep for the majors, even if it's only for a month.

Of course, if we're really in need of pitchers against the Yankees, we could go get Andy Marte from Cleveland...I always love watching Nick Swisher strike out on three pitches.
