"He hasn't developed his feel for the strike zone yet, but you don't want to take away that aggressiveness." I heard it when José Reyes was coming up, and I heard it when Amed Rosario was coming up — even as both swung at balls from their ankles to their eyebrows, and both ran into developmental hurdles. Now I see Ronny Mauricio hitting 26 homers last year, but pumping out an OBP of only .296, and the refrain carries on. Is there any truth in this? Why wouldn't we want our fastest guys to be learning to lay off of pitches as early in their careers as possible. Is there a double standard? Why is aggressiveness a virtue for black Dominican infielders, but restraint a virtue for David Wright and Brandon Nimmo? That you-can't-walk-off-the-island nonsense has to be universally dismissed by now, but there seems to be some trace elements remaining.
