It will be tough, that's for sure. I think if the O's had signed Upton and Alvarez to DH, we'd arguably have the toughest lineup. While I dont really believe it, hearing we are still in on Cespedes on a 2-3 year deal. Adding him to the OF would also make our lineup pretty nasty...and add a 5th gold glover to a top defense.
At the end of the day...pitching is going to be our problem. Even if we add one or two of Fister, Latos, Gallardo, I dont think it makes us all that much better.
