I like this guy a lot more after having seen him in person, which I did today.
He played 2B and looked comfortable there, although he just needs more reps. Couldn't judge him off SS other than "yes, I could believe that dude could also possibly play SS." No red flags, in other words.
At the plate, approach was okay, decent swing plane leading to decent results. The ball got to the good part of the bat in 3/4 ABs (1 K) despite going 0-4, and he's got pretty good ability to get his hands to the right place. He's definitely got some physical projection and that could really, really make a difference. A little bit more strength throughout his body and he'd likely have been 2-4 with a homer.
He's still very young for level and needs to hit the weights (and especially not skip legs day), but I can see why they traded for him. Easily the most promising IF on the FredNats roster right now, although he needs to repeat the level for at least half of last year. But 15-20 pounds of muscle could really help this guy.
