Flores is fine. Even if he doesn't hit well he's still an upgrade over Lo Duca and Estrada because of his defense. It'll be good for Jesus to come up here for a while (hopefully permanently) so he can work with the coaches and improve.
Dukes has only had a limited number of ABs in AAA. He's done alright. It'll be interesting to get another look at him. I hope he tears it up.
