Jairo Diaz is another we-should-see-what-we-have type of September call-up, if only because the Rockies (theoretically) acquired him for a reason when they moved Josh Rutledge over the winter, so it might as well be time to see what it is with the flamethrower that the Rockies liked so much.

The downside? Well… he’s wild. Not like Rex Brothers wild, but nearly so; he’s walked 37 and hit four more in 54 innings while allowing six homers and going 3-5 with a 4.67 ERA.

Nevertheless, with the fastball Diaz has… he’d be an interesting addition to the Colorado Rockies’ big league bullpen if he can refine his stuff just a little bit.
