Experts take early stab at Top 10 Draft picks

MLBPipeline's First-Year Player Draft experts, Jim Callis and Jonathan Mayo, took their first shot at projecting the first 10 picks back in December. Now that the Top Draft Prospects list has been expanded from 50 to 100, they're back to update their educated guesses.

1. Astros
Callis: Brady Aiken, LHP, Cathedral Catholic HS (San Diego) -- Combines stuff and polish better than anyone in this deep pitching class, including the college arms.
Mayo: Carlos Rodon, LHP, North Carolina State -- He'll solidify his place atop the Draft before June.

2. Marlins
Callis: Rodon -- Entered the year as the strong favorite to go No. 1, and despite a good but not great spring, he could still get there if his 15-strikeout outing against Georgia Tech on Friday heralds a strong finish.
Mayo: Tyler Kolek, RHP, Shepherd (Texas) HS -- The Marlins like young pitchers with front-line potential. Kolek and his 100-mph fastball fit that description.

3. White Sox
Callis: Kolek -- Chicago loves power arms and high ceilings, and no one in this Draft class throws as hard as consistently.
Mayo: Jeff Hoffman, RHP, East Carolina -- Assuming he's healthy, he fits the mold of college arms White Sox like, but with more upside.

4. Cubs
Callis: Hoffman -- Before he missed his start last weekend with minor arm soreness, Hoffman was pushing past Rodon. If healthy, he'd be a nice fit for Chicago.
Mayo: Aiken -- Could very easily go in the top three, and I can't see him going any later than this.

5. Twins
Callis: Alex Jackson, C/OF, Rancho Bernardo HS (San Diego) -- Easily the best position player available, could become a full-time right fielder to expedite his bat to the big leagues.
Mayo: Jackson -- Best bat in the class, but will he stay behind the plate?

6. Mariners
Callis: Aaron Nola, RHP, Louisiana State -- College baseball's top-performing pitcher should be the first starter from this Draft to reach the Majors.
Mayo: Nola -- Has performed his way up this high, can get to bigs quickly.

7. Phillies
Callis: Nick Gordon, SS, Olympia HS (Orlando, Fla.) -- Has passed North Carolina State shortstop Trea Turner to become the best up-the-middle player available (assuming Jackson is moved to the outfield).
Mayo: Gordon -- A year after J.P. Crawford? You can never have too many shortstops.

8. Rockies
Callis: Kyle Freeland, LHP, Evansville -- Throwing two above-average pitches and filling the strike zone just might be the formula for success at Coors Field.
Mayo: Tyler Beede, RHP, Vanderbilt -- Could join Jon Gray and Eddie Butler in a dynamic rotation.

9. Blue Jays
Callis: Touki Toussaint, RHP, Coral Springs (Fla.) Christian Academy -- After failing to sign Beede (2011) and Phil Bickford ('13), Toronto finally lands an electric high school right-hander in the first round.
Mayo: Sean Reid-Foley, RHP, Sandalwood HS (Jacksonville, Fla.) -- The Jays love high school pitching, and they're not afraid to surprise.

10. Mets
Callis: Bradley Zimmer, OF, San Francisco -- Though New York's past three first-rounders have been hitters, it could go for a fourth in Zimmer, this Draft's best all-around college position player.
Mayo: Zimmer -- In a weaker class for college bats, Zimmer's tools and performance stand out.
