Hmm. Definitely Wieters, Wright, A Ramirez, Bay, Upton, Nolasco, Soria, Gallardo, Oswalt, Hanson IMO. Most of these guys are young, and all have proven they can be valuable fantasy commodities at the major-league level. I'd probably spend a spot on one of Sheets or Webb as an injury-risk potential ace, but I'd hold off on that decision until we find out how Webb's surgery goes. I'm assuming here that you don't actually have to make the decision on your keepers until the end of the year?
I want to say a high-upside young pitcher like Buchholz or Porcello with your final spot, but I'd be a little cautious about keeping seven pitchers. Is there any chance you can swing a deal for an equal-value hitter for Nolasco, Gallardo, or Oswalt? If not, I might just keep Ludwick. You don't want to start your year off with an offense full of question marks.
