So I guess you won't be answering my question.
I've seen Brentz play plenty of times. He's a corner outfielder with no shot at handling CF. He does have a good arm, but that is where his MLB skill set ends.
As a fourth OF he probably won't bring down this team. But if there is a need for him to play for an extended time, the Sox best hope is he can maintain the luck he had over his first 90 plate appearances. That he struggled for 4 full seasons in AAA, partially due to a couple injuries, doesn't and shouldn't lead anyone to believe he can make rapid adjustments to MLB pitching.
I think he makes the opening day roster. I don't think he will stay on it all year unless the outfield stays very healthy. Right now his biggest skill is the willingness to work for MLB minimum wage.
Did you ever see anything different in Brentz?
