Jesus christ, why do people keep saying this? If they don't sign Edwin/Jose, they will be signing/trading for guys to replace them. It's not like Thole, Junior Lake, and Barney will be everyday players next year.
You obviously don't realize that they matchup different divisions for interleague each season. This year its AL East and NL West. Last year was AL East and NL East
I still don't think Baltimore will win the division. They'll most likely grab a wildcard though. They're just not a good enough team, and their offense will not be this good for much longer.
