I can see both sides but I just think Velasquez has earned a spot. His value is also tied to keeping the rest of the pen fresh. If he goes like a week between appearances, then ya stretch him out in the minors, but I think he has as much if not more usefulness as Poyner to the current roster. They really haven't been tested in a long grind yet due to all the off days and the rain out so having a few guys who can go multiple innings may be more helpful long term.I would if only because two potential spot starters (Velazquez and Johnson) sitting in the pen is essentially having no spot starters at all after a while. Barring injury or a long extra inning game, how frequent will the need for a true long-man be with this rotation? Certainly not enough to necessitate two guys who can throw 40-50+ pitches per outing when necessary. Without regular opportunities to throw that many pitches in a game, they're going to turn into 30 pitch maximum guys quickly.
Also -the odds of Velazquez being lined up for a spot start to coincide with an injury are pretty low.
