A lot to like to me.
Shows the bottom of the front foot, strong landing leg, nice glove, good external rotation. Repeats well. I would imagine he does very well at this age.
I am not a "mechanics" guy really, a lot more knowledge people on here than me in that regard, but, I really like what I saw.
I like the outfielder too....east to forget how boring it is being an outfielder a lot of that time at that age.
