Twins Sign RHP Cody Allen (Minor League Deal)

The risk is that he stinks and that he costs 2, 3, or 4... games before the Twins move on. Maybe the Twins can afford that. Maybe it's worth the risk; it probably is. But there is definitely a risk.

How can he cost the Twins games from AAA?

I doubt they'd call him up if they haven't fixed his issues.

How can he cost the Twins games from AAA?

Hypothetical Scenario:

He appears to pitch great at AAA. He gets called up. He stinks and costs the Twins games. 

Hypothetical Scenario 2:

He doesn't even pitch well at AAA. He gets called up anyway because of cognitive dissonance. He stinks and costs the Twins games.

Hypothetical Scenario 3:

He pitches great at AAA. He gets called up. He pitches fine, maybe even well, for a while. The FO thinks the bullpen problems are solved and don't acquire an actually good relief pitcher. After it's too late to do anything about, maybe in the postseason even, he stinks and costs the Twins games and maybe even the season. 

Those are three realistic scenarios. I'm not saying they are likely. I'm not saying I think it was a bad signing. People are saying there is no risk. I'm pointing out that there is. The risk is that he performs badly and costs games and takes the roster spot of someone who might've performed well.

Best case scenario is Twins help him repair his mechanics (whatever is making it easier to hit his pitches, yo) and recover in the way of setup or co-closer that which was lost when Presley was traded away. That would be best case.

20BBs in 23IP is bad.

Velocity drop is bad.

29Ks is good.

(High fastball spin rate good, poor tunneling bad; thanks Parker!)

Track record, albeit not too recent, is good.

That the Twins pitching coaches want to get a chance to work with him, is good.

Seems fairly low risk, decently high possible reward.

Worth a shot.

Hope it works!

I'm not sure what #1 even means. "Appears"? The Twins will have eyes on him, and all the analytics. They'll know if he's pitching well or not. We might have to rely on appearance, but not them.

As for #2, I just can't see them calling him up if he's not fixed. You can disagree, of course, but I disagree that this is even a possibility.

And #3 seems quite far fetched. The FO isn't going to stand pat. They are going to acquire legitimate quality bullpen pieces before the deadline. They have the payroll flexibility, prospect capital, and a clear need.

I meant by "appears" is that he pitches well enough by combination of stuff and experience to get out AAA hitters and put up good stats. He could be good enough to get AAA hitter out but not good enough to get MLB hitters out. 

I hope you're right. You probably are. I still don't think any of the scenarios are implausible, maybe unlikely, but not out of the question or even without precedent. 

It seems possible to me, that whether or not he is "fixed" (which is just a muddy a term in this context as "appears" was in mine) he will be given an opportunity because of his past success and because of his relationship with Falvey in Cleveland, not to mention the state/performance of the current bullpen.

Those are good reasons. It seems worth the risk to me. It is not without risk.
