I'm also from Chi-town area. The guy, right now, hasnt a clue. He lunges at outside pitches, gets consistently fooled on inside pitches.
He's guessing, not attacking the ball. He'll get you a HR a week just on sheer power. If thats what you need then get him. For avg, dont look for any .300 tho. He'll look good one day and youll think he's broken out then he'll suck the next 2 days. Its off and on for him.
