It also let’s us get a better look at some of these prospects, to see what we have. I think it’s smarter to be patient and not start trading our big trade chips just yet. Hernaiz was definitely expendable, so I’m really happy with this trade. Ideally, by the trade deadline, Holliday has shown signs that he’s the future at SS and we can confidently trade from our depth at SS to improve our pitching again.
I don't think he's ever going to comfortably part with the top guys in the system until there are clearly established players on the ML team that would actually block those players he'd be looking at trading. For example, I think once Gunnar and whomever of Westburg/Norby/Ortiz/Mayo lock down two spots (and assuming Holliday is ascending), at that point he'll look to trade whoever hasn't earned regular playing time (but is hopefully still maintaining trade value by performing well in AAA). I think he's worried of trading the wrong guys and having whoever he's left with bust at the ML level, especially if it's in pursuit of a pitcher with minimal long-term team control.
Looking at some of his stats for the last two years, he really looks like the type of guy we would've ran out there for the 2012-2016 teams. H/9, K/9, BB/9, HR/9, WHIP, and K/BB all fall into ranges you would see from Tillman, Chen, Miguel Gonzales, Bud Norris, etc. They all generally had higher ERA+, I assume on account of the ballpark factors?
At a glance his numbers from his two years in Oakland match up very similarly to Chen's first two years in Baltimore (2012-2013). I'd be interested in how their stuff compares and if there could be a comp there for those who may know more.
I don't think he's dominant by any stretch, but I'm hopeful he can be a solid SP to a playoff rotation over the next four years.
I guess the only question left is whether Urias and Mateo are still on the opening day roster. The IF still seems a little crowded with Westburg and Ortiz knocking on the door.
My guess at this point is they both start the season here but at least one of them is in another uniform after the trade deadline.
