Marrero's draft stock had dropped during his senior year of high school, but not enough for the Nationals to pass on him in the first round. He quickly jumped on the fast track in his first full year, moving up to the Class A Advanced Carolina League as a teenager. The kid can flat-out hit. He can hit for both average and power and should also draw a fair number of walks with his excellent approach at the plate, especially for someone so young. A converted third baseman, his outfield play was fine, flashing a decent arm from left field. He's never going to be a threat to steal bases.
That bat will get Marrero to the big leagues in a hurry. The Nats' system is deeper than it's been in the past, but Washington won't get in Marrero's way. He won't turn 20 until July, but look for him at the upper levels of the Minors in short order, with a September callup a possibility.
