Hill needs to get some swings, and Miley should be a good matchup for him. Also, Holt is looking a little banged up (diving back to base isn't just a problem for Steven Wright). Furthermore, Holt may be needed to spell Bogaerts at shortstop. Xander has worn down at the plate, and looks like he could use a few days off when tough RHP are on the mound.Perhaps because of the title of this thread? As far as the proposal - I like Holt too but it just so happens he had a great day. The next time Brock goes 0-4 and has a bad day in the field then he'll probably be back to advocating Moncada get another chance. Too much kneejerk thinking here.
Shaw-Hill isn't a great platoon at 3B, but it's not bad, considering the strength of the rest of the lineup. I'd hold Moncada out strictly for pinch-running duty when no base-stealing is required. He may be 21 years old, but his judgment is still a teenager.
