We had a piece on this yesterday, but it was more focused on Rafael Betancourt being designated for assignment by the Rockies; Simon Castro and Jairo Diaz are the two men who will fill out the bullpen, at least for the time being.

Neither pitcher threw on Monday in Atlanta, but on Sunday afternoon at Coors Field against the New York Mets, Castro tossed two scoreless innings allowing two hits, and Diaz added a scoreless frame with just a walk allowed.

Walt Weiss liked what he saw from them:

"“I thought they did a great job. Simon settled in after some issues in that first inning, but kept them from scoring. And I think Diaz showed why we like him — the power that you envision at the back end of a bullpen and the swing-and-miss slider.”"

Castro had a pretty decent year in the hitter-friendly Pacific Coast League, while Diaz struggled with his command there, but has a plus-plus fastball and a power slider — tools that make big league coaches drool with the thought of being able to corral him enough to be a lockdown late inning reliever one day.

Either way, we’ve written about these two before; they each deserve a shot in the big leagues, and it’s good to see the Colorado Rockies deciding to give each one a try to figure out what they might have in 2016 for organizational depth.
