I've never seen Moncada play yet personally. Last summer I witnessed Benintendi go 2-4 (2nd Pro game vs Tri-City) first Pro HR (2-run shot) & first Pro SB. From what video I've seen and from what I've read of Moncada, he's some kind of man-beast and his physical stature makes everyone else seem unimpressive, w/ talent galore. Though Benny is by all accounts definitely the more polished player at this point. There are reasons why Benny got promoted to AA a month before Moncada did. Just sayin'.
Can you imagine a MLB lineup of Betts (RF), Bogaerts (SS), Bradley (CF), Benintendi (LF), and Moncada (we'll say 3B), plus whoever (2) out of Vazquez/Swihart/Leon at catcher. Filled in by veterans like Pedroia, Hanley, Hill ... for 2017? Does anyone share in my excitement of this possibility?
