I'm in a Diamond Mind dynasty league, and I have the 5th pick in a rookie draft.  The two top pitchers that will most likely be available at that time are Matusz and Porcello. Both have a lot to like, and are very young.  I've never seen them compared before, most likely because Porcello already has a year in the majors, and that they are very different pitchers.

My question is, who do you think will have the better career?

Clay Buchholz  for  Okajima, 2nd Rounder , 3rd Rounder

I only have 1 viable relief pitcher in Manny Delcarmen (who has a terrible WHIP), and no closer for the upcoming season.  The draft picks are in the rookie draft - players qualify based on 75 AB's or 25 IP.  This year will be a deep one.  The second rounder at this point  would end up being the 31st pick or so overall.  I drafted Buchholz 9th overall in last season's draft.
