Kings of Kaufmann posted an
update about Yordano Ventura that includes some nice video of him.
Check it out.
The thing that's crazy about Ventura is that he produces crazy velocity and isn't max effort. There are a lot of guys his size that produce that type of velocity (Lincecum, Bauer, Timmy Collins), but they are much faster down the hill than Ventura.
Looking at his mechanics, his arm action is easy and he has nice shoulder/hip separation and whip (which is why he throws so hard despite being 5-11/160). He's not getting much of that velo from crazy mechanics or max effort, which is probably why injuries have not been an issue with him so far.
His load is good, which means elbow health shouldn't be a major issue for him. A lot to like there.
He actually reminds me a little of Bob Gibson, which is weird (considering Gibson was a monster and had 1960s mechanics). But the way he loads and the separation/rotation he gets as he delivers the pitch remind me of Gibby.
