I agree on keeping him at AA for another year (let him stay at AA for another year, he is much younger than most of the competition there), but disagree on the defense. The negative defensive reviews he has received at first over the years is likely more a result of the position change. Marrero has very good range (makes a bunch of good dives) and has been picking balls out of the dirt and grabbing those that are destined to sail over his head much better than he has in any of the previous seasons. Players improve at their positions over time, but Marrero seems to still be dogged by the early labels that were attached to him. And while I love this kid's bat potential, he needs to make some adjustments before he can realize his full potential in this respect. He seems to go for the big hit quite a bit, when he has the ability to place the ball and get a ton of gap doubles.
