from NFA:
With pick #232, the Nationals select Roberto Perez a SS from HS in Puerto Rico; he’s a relative of Dickie Thon!!! from PGCC “An angular 6-foot-2, 175-pound shortstop, Perez is a nephew of former major-league infielder Dickie Thon and long-time Rangers scout Frankie Thon, and cousin to potential top 2010 Puerto Rican prospect Dickie Thon Jr., so the baseball genes are on his side. Perez has very good defensive tools and skills in the middle infield. He’s a 6.7 runner in the 60 with easy, gliding actions and balanced footwork around the ball. His throwing arm is among the best in the 2009 high-school class and his throws carry easily across the diamond. He’s also a pitcher of some note with an upper-80s fastball. Perez’s defensive game is ahead of his offense at this point. He shows very good bat speed at times and gap power, but has an aggressive, drifting approach at the plate that leaves him off balance frequently. Perez is a good student from an educated, professional family and has signed with Oklahoma State, so his signability may not be as automatic as it is with most top Puerto Rican prospects
