On Monday, MLB.com named their top ten breakout prospects from the Arizona Fall League this season and two of the ten are members of the Colorado Rockies.
One of them was right-handed pitcher Justin Lawrence. Lawrence, who is ranked as the Rockies 17th best prospect by MLB.com, did blow two save opportunities in the Fall Stars Game and the AFL Championship game but he showed his fastball quite frequently, which hit 100 MPH on a few occasions as well as an above average slider.
His problem is control as he averaged more than 5 walks per nine innings.
