Mayo's NEW TOP 20 PROSPECTS. Here's the short list of potential Cubs first round pick candidates next year: 3. Alex Jackson, C, Rancho Bernardo HS, Calif.: A two-time participant in the Under Armour game, Jackson has some serious raw power from the right side and is a good leader with an accurate arm. 4. Touki Toussaint, RHP, Coral Springs Christian HS, Fla.: This Florida prepster is very athletic with a ton of arm strength, using a clean delivery to fire fastballs that can touch the mid-90s to go along with a hard downer curve. 5. Aaron Nola, RHP, Louisiana State: What's a Draft class without a top LSU arm? Nola was LSU's Friday starter this year, going 12-0 with a 1.68 ERA, striking out nearly a batter per inning while holding hitters to a .187 BAA. 6. Trea Turner, SS, N.C. State: He's a shortstop who can stay there, a leadoff hitter extraordinaire with plus-plus speed that allowed him to steal 84 bases in his first two seasons of college ball. 7. Nick Gordon, RHP/SS, Olympia HS, Fla.: The son of Tom and brother of Dee, Gordon is a legitimate two-way guy who can play shortstop and hit from the left side. He's athletic on the mound, too, with a low-90s fastball and a big curve.
