Cooper was drafted in 2010 by Arizona in the 12th round. He was 4-2 with a 3.57 ERA in 41 relief appearances. He combined for Double-A Mobile and Triple-A Reno this year. He was on the Southern League All-Star team, compiling a 1.85 ERA in 24 games with Mobile. He is 16-15 with 16 saves and a 3.27 in five Minor League seasons. He has reported to the Cubs’ Double-A team in Tennessee since there are a lot of pitchers down at Triple-A Iowa. The Cubs will work on his mechanics down there since he has struggled since his promotion.
Jackson was once considered to be one of the Cubs’ top prospects due to his combination of power and speed. However, he’s had serious problems with his swing resulting in many strikeouts. He also has had problems staying healthy. He still has the physical tools that made him a great prospect and is still a very good defensive outfielder.
Throughout the era when Jim Hendry was still the G.M, there were several prospects that didn’t work out, which always left the team with a weak farm system. Hopefully with a change of scenery, Jackson will go back to the phenom he once was when the Cubs drafted him.
