I think it's obvious at least defensively Polonco isn't ready yet. I can see him up in September, but I'm guessing for now they want to give him everyday reps while they can. I think almost everyone would like to see Arcia up in platoon against RHP and PH situations and I believe it will come, but right now they feel content on giving him everyday AB's, but I wouldn't be surprised to see him sooner than later. I would assume it would be pretty low chance we see Berrios before September. IMO, having him keep starting in AAA, where he has only been a short time, is better than him in the pen pitching a handful of innings per week. There are several candidates that IMO should have replaced Boyer months ago.
