Here's a snipet of the article from MLB.com:
Before the team had made its decision, Rays scouting director R.J. Harrison called Beckham "a really good player at a premium position."
"Middle of the field player, very good athlete, an advanced bat," Harrison said. "Has a real good awareness on the field. He plays the game with a great deal of enthusiasm. And then when you spend time with him away from the field, he's the same guy. He's a fun guy to be around."
...Beckham stands 6-foot-2, 190 pounds, which lends him the physical stature to play most positions. Harrison said Beckham "absolutely" will be a shortstop in the Rays organization. A five-tool player, he is said to have the prerequisite range to remain at shortstop.
I've heard it said that Beckham's got some holes in his swing, but that he has good "hitters'-hands", and should excell under the proper tutelage. I, for one, look forward to seeing him progress through the ranks.
