Anyone wish the Reds had sent him down and kept Arredondo, instead?

I know he's had a lot of success in the minors, and had very good numbers with the Reds last year (and in ST).

But just watching him I can't exactly see how he does it. We've all heard that he hides the ball well and so he looks faster than 91/92. OK. But then I wonder if he really has a secondary out pitch.

And I think that talk about him being a future closer was always a reach.
