I'll get to the other questions when I get a chance. I appreciate good questions, I have done so much research that it's good to get some of that info out.
Good question, the main reason to pick Alemais rather than Hechevarria is you have nothing to lose and Alemais will cost 655K (100K Rule 5 fee + league min) and is controllable for 6 years if he works out while Hechevarria might get similar to the 3M he got last year and if he's good, he's either more expensive or gone.
That said Alemais isn't at the top of my list or particularly close, I just think he's worth thinking about and I haven't heard him mentioned anywhere else.
For the Holt question, it could either be guys that fit the same profile that I mentioned earlier. So vertical spin angle, hop on the fastball, high 3/4 arm slot, above average spin. Or it could be guys that have some fixable pitch arsenal things, like a guy whose curveball and slider are too similar, or whose curveball doesn't mirror fastball spin, or who unintentionally cuts his fastball.
Guys that fit the profile include Joe Barlow, Trevor Megill, Brandon Bailey, Hever Bueno, Jordan Sheffield, Bryan Baker, Wladimir Pinto, Scott Engler, Kevin McCanna in a rough order of preference. Some of these guys aren't legit options, I'm just pulling all the guys I have notes on fitting that profile.
Guys that have some correctable flaws include (this is a limited list because I don't have time to extensively study video on every player) in no particular order Luke Bachar (more seperation of breaking balls), Daniel Alvarez (fastball spin angle), Cam Hill (spin efficiency of the fastball), Eric Marinez (release consistency), Andrew Lee (cuts his fastball), Kurt Hoekstra (cuts his fastball).
I know. I was joking. I appreciated him asking for questions.
It just struck me as funny that he asked for questions over an hour ago and he hasn't posted since. Maybe I asked bad questions.
