Many regard North Carolina shortstop Dustin Ackley as the best hitting prospect in the country. The Nationals are expected to take Stephen Strasburg, which would leave Ackley for the Mariners, who have the second overall pick. "Everyone is saying, 'It's Strasburg and everyone else,' " Baseball America's Jim Callis said. "It's Strasburg, and the clear No. 2 is Ackley."
