I hate when people say conditions are going to make HR impossible (marine layer, wind blowing in hard). The Cubs always find away to defy mother nature.
I don't think it's horrible if EPatt occasionally gets starts in the outfield, just so he's comfortable there and has that ability on his resume. But he should definitely be starting at 2B for the most part.
So Mark O'neal and/or Larry Rothschild can get a first hand look at him. Wood was with the team recently, joining the team just means he'll be there. That being said this is the Cubs, so he'll start sometime this week.
