Probably, a lot of Sox young pitchers might be happy to just make the pen.
I'm not sure some can do much more at the AAA level to prove they belong, namely Wink and Seabold who both had very nice OPS Against at that level. Some say Murphy is best suited for the pen. Crawford is a tough call.
My guess is Mata, Bello and maybe Walter or Wikleman are our best shots at starters.
