.605 can stay if he's ready to develop off it. I'm not sure that's the case, but on a team this bad, I'm not seeing why the number itself would be prohibitive. Robles is at .607 and Cesar's at .622 and neither of them has the excuse of being 21 years old. I'd be fine sending him back down - it's not like he has a ton of AAA at bats or even AA - but I'm not seeing a massive imperative. It just depends on where he's going to learn faster.
to be a bit crass, is this a justifiable use of his service clock? He had about 5 weeks in the minors, so we have 6 years. I guess we aren't going to keep him in the minors for 2-3 months next year to keep the 6 years after. If he had something like 3 months service time this year, could you see him staying down until late May / early June to pick up another year?
