My son likes to watch Javy Baez (I know this player came up in previous threads mentioning 6th tool). RipkenFanSon particularly likes Baez' positioning , quick tags, and overall awareness.
Not related, to the above, son had a "6th tool moment" in a college game. Opposing third baseman made a crucial error, and he was shaking his head as he returned to his position. The next inning he struck out, still muttering as he took warmups in between innings, and kicked a little dirt. Son sees all this and says to himself, this player's head is not in the game. As he approaches home plate son is thinking, "There is no way he'll be able to field a bunt." First pitch of the inning as son leads off- bunt single to 3rd base.
