"The only team that can really know what they're going to do is No. 1," he said of the Astros, who have the first selection.
In 2012, nine of the Cubs' first 12 picks were pitchers, and last year, they chose 11 pitchers in the first 15 selections.
In his latest mock draft, MLB.com's Jim Callis predicted the Cubs would take Oregon State outfielder Michael Conforto in the first round if North Carolina State pitcher Carlos Rodon isn't available.
The 2014 Draft will take place from Thursday through Saturday, beginning with the Draft preview show on MLB.com and MLB Network on Thursday at 5 p.m. CT. Live Draft coverage from MLB Network's Studio 42 begins at 6 p.m., with the top 74 picks being streamed on MLB.com and broadcast on MLB Network.
