Also in this edition of Baseball America is a breakdown on each team's 2012 draft class. As you might expect, BA's draft experts, Jim Callis, Conor Glassey and John Manuel, tie the eventual success of the Nationals' 2012 draft to first-round pick Lucas Giolito, the prep right-handed pitcher who underwent Tommy John surgery in August. Giolito was ranked by Baseball America as having the second-best fastball of any pitcher in the draft, but the Nationals will need to wait until deep into next summer before seeing the 18-year-old let loose again following his surgery, which was performed by Dr. Lewis Yocum. Baseball America lists second-round pick Tony Renda, a second baseman out of Cal-Berkley, as being the best pure hitter taken by the Nationals, and fourth-round pick Brandon Miller, an outfielder from Samford University, as the best power hitter in the Nats' draft class. Sixth-rounder Hayden Jennings, from Evangel Christian Academy (La.), is listed as the fastest runner in the draft class, while shortstop Stephen Perez, an eighth-round pick out of the University of Miami, was singled out as the best defensive player. Right-handers Derek Self, taken in the ninth round out of the University of Louisville, and Robert Benincasa, a seventh-rounder out of Florida State, are considered the closest to the majors, according to Baseball America, but it's also mentioned that Giolito could move quickly once he's fully recovered from Tommy John.
