I think that the White Sox should consider acquiring Brian Barton, an OF in the Cardinals organization. His minor league numbers show that he may be a decent leadoff hitter at the big league level. In 153 AB last year with the big club, Barton posted a .354 OBP. He looks like he has 30 double, 6+ triple potential with probably <10 HR. He could steal 20-30 bases in a full season.
I don't know how he is in the field, but I don't think he'd be any worse than Owens.
