Last August the Cubs brought up prospects Josh Vitters and Brett Jackson, giving them a chance to show if they were ready for the big leagues. They both had put up decent numbers in the minors, but didn't do anything close to that with the Cubs. In fact, they both were really, really bad.
Were they rushed to the majors too quickly? Nope--they were just over their head. This year both are in AAA and not doing much at all. I think their Chicago numbers were just an indication that they aren't prospects we can count on in the future.
This year, the Cubs have another prospect that's been tearing it up in both A and AA--Javier Baez.
He played in several games for the Cubs in Mesa this spring and did really well. He has stayed hot all summer long and I think the Cubs should bring him up in September and see if he's ready for the majors.
The team is 54-72 and in last place. They've got nothing to lose. Let's see what Baez can do in the bigs, now.
