So, I acquired a couple of young pitchers in exchange for a slightly older player in a trade this year.  One was a pure prospect, but this guy had seen some major-league time:  http://whatifsports.com/HBD/Pages/Popups/PlayerProfile.aspx?pid=4133170.  I didn't have room for him on my ML roster, though, so I sent him down to AAA, where I have a good pitching coach, to get some finishing touches.  About 30 games before the end of the season, I had two injuries on my ML staff, and I decided to call him up since I was paying him an ML salary anyway, BUT I had forgotten to put him on the 40-man earlier.  It just so happened that I called him up one or two cycles after the deadline for setting post-season rosters.  He cannot play in the postseason (which it looks like I will make).

My Question:

The kid's still impressionable, and probably has a development cycle left in him.  The original pitchers on my ML roster are now cured.  I'm thinking about demoting him to AAA to play in the playoffs.  If I called him up while I had another player on the DL, do I have to worry about him suffering a demotion penalty?  Is it worth bouncing him down if he could potentially get another 15 games playing the playoffs with my (very good) AAA team?

If you called him up on the same move as the DL, do the DL Remove and demotion at the same time.  If you didn't, wait til next season or he might take a hit.

Ouch...that's what I was worried about.  is the programming that picky?  Could you double-check my eyes to make sure I did the DL assignment and promotion right?

Here's the guy who he replaced on the ML roster:  http://whatifsports.com/HBD/Pages/Popups/PlayerProfile.aspx?pid=2963448

And here's the young guy again, just to make it easy:  http://whatifsports.com/HBD/Pages/Popups/PlayerProfile.aspx?pid=4133170

You did both moves on 3/1/2012, 2:05 PM, but did you do both moves with the same "add roster moves" submission? I think that's the way it needs to be.  However, Mcinerney has a ton of patience, so you can probably demote him worry free.  Another thing - he was on your 40 man roster at the "set postseason roster" deadline, so he should be eligible to play for your team in the playoffs.

But why am I giving you advice?  That could bite me directly in the ***!

Oops I'm wrong.  I was looking at mmiller's add to 40 man transaction way back on Jan 19th.  The patience point stands though.

They appear to have been done simultaneously.

Thank you both.  And shobob, your magnanimity knows no bounds.  I would like to think that Leo Durocher was right, and that it will bite you in the ***, but this season, like all the other seasons, your goodwill will probably only be overshadowed by the Maroons' complete and utter dominance of the NL North.
