One thing I saw come up repeatedly with our hitting prospects: they're mostly ground-ball oriented. Over and over, it seems like he praises a guy's bat speed but says he's unlikely to hit for power because he has a ground-ball swing plane.
I think going back since the day Rizzo arrived we've been looking for guys who can spray the ball, play good defense, and run the bases. A lot of our highly drafted hitters are middle infielders and defense first outfield types. Go find power in free agency.
And the guys in our system who want to be power hitters have either not really developed so far (Ward), got hurt (Skole), or faded into oblivion (Keyes). On the other hand, the Nats have a small army of minor league middle infielders and outfielders who are fast as heck, solid gloves, and can play anywhere.
The Skole injury sucked. I remember back when Rizzo was saying he was the lefty first baseman of the future and both Davey Johnson and Matt Williams spoke highly of him. I don't see another player in the organization who even come close to profiling as even an average MLB power hitter.
