I picked up a guy in the Rule 5 draft who was a AAA-quality pitcher who got a huge DitR bump the previous season. I decided to see how much I could develop him without wrecking my team; the goal was to get him as many 5-pitch outings as possible. Here were the results (he got hurt a little before roster expansion, would have got 140 games):

Season	Fran	Level	G	W	L	SV	SVO	Inn	H	R	ER	HR	BB	SO	OAV	OBP	SLG	WHIP	ERA
54	FRE	ML	125	1	3	1	4	66.2	66	33	32	6	18	42	.252	.299	.366	1.26	4.32

The development outcome kinda disappointed (I did this in S54, hoped for more after the massive S53 DitR bump)

Event	Season	St	Con	VsL	VsR	Vel	GB	P1	P2
Spring Training	53	33	75	30	38	26	53	57	64
Spring Training	54	47	84	45	55	26	54	64	64
Spring Training	55	48	87	52	63	26	54	69	69

But that's not the point. The point is, how did I get simmy to choose my worst pitcher 125 times? To do this, I took advantage of the fact that when the sim chooses a starting pitcher to relieve, it reliably chooses the pitcher farthest away from the starter, and works its way back towards the starter. So I set up my staff with:

1. The DitR as the only reliever; SuA or SuB doesn't matter
2. My today SP as SP1, and my tomorrow SP as SP2.
3. The 4 relievers I wanted to use for any given game lined up as SP6-3, in that order.

I don't recommend this strategy in the majors unless you have several relievers whom you can give 20/25 pitch settings, and who are all about equal in quality to each other; this happened to be true for this staff. I also don't recommend using this strategy unless you can really tweak your setting every single freakin' 8 hour cycle; all hell breaks loose if you miss two games, and even one miss can get moderately ugly. But I might try this in my minors, to maximize top prospect development; there are some 3 month parts of my year when I can pretty reliably update my staff settings every 8 hours, and I care much less if all hell breaks loose at High A anyway.

Nice. I've done some similar things in the minors. I use mop up for all pitchers unless they're a true prospect. I had one of those DITR type pitchers get 125+ games as well.

That "furthest away from the starter" thing is good Intel. Thanks for sharing.

I tried stealing the mopup idea but I notice that simmy is using my other SP's before the mopup guys, which tires out my entire minor league rotation. Any way around that?

I was running into that, too. So, I made sure that my SPs didn't have the relief pitch checkbox checked and that helped. I eventually got to a point where I ran one starter per cycle and when that same starter was scheduled to start the next game as well, he was deactivated.
