Jim Callis just released his newest mock draft on MLB.com and he has the Pittsburgh Pirates taking prep outfielder Monte Harrison. Last week, Harrison was the choice from Baseball America.

Harrison is a three-sport star, who may have the highest ceiling of any position player in this draft class, but he also comes with some risks since he hasn’t concentrated on baseball only. He offers strong defense, a cannon for an arm, good speed and raw power. There are some questions around his bat, as to whether he will hit enough to make good use of that power and speed. Harrison would be tough to pass up with the 24th pick if he is still there due to that five-tool potential and athleticism. The Pirates have good depth in the outfield in their system, but due to his inexperience, he wouldn’t be someone that moves quick and plenty could change over that time.

Earlier today, Baseball America released their third mock draft and had Kyle Schwarber going to the Pirates. You can also view their top 200 list here and our fourth draft preview here, which includes a video and scouting report on Monte Harrison.
