take a look at my post if you get a chance
I'd keep Walker in there unless he struggles. I think he could be back to 40 HR with a nice avg. Hitters look good, though.
Pitching looks good too, especially RP, except that Mota may go on DL. Is Marte available? Probably not , lol.
I'm not too confident in Lawrence as your 5th starter, but I suppose you have good replacement options on the bench with Jackson and Affeldt. One of them ought to startt he year off decent.
