Re: With the Break Approaching...
If Hamilton can be at least a major league average SS defensively, he should stay there. I've only seen two games, but it seems to me there is work to do defensively. I would leave him at Bakersfield and Didi at Pensacola unless Janish moves up and there is a vacancy.
I would leave Stephenson at Billings where it will be easier to limit his innings and bring him along slowly. There are enough pitchers at Billings to limit innings for the kids and the college arms that already have some innings this year. Ditto for Cisco, Mulgarian, and Romano. The Reds have the luxury of not having to rush pitchers up the ladder. I'd be tempted to move Smith to Pensacola, Quezada to Bakersfield, and give Dennhardt a chance to start.
Too early to decide on Rosa or Rahier.
