Right but since we're not using either in a competitive game it also doesn't matter who gets the nod. It's not a small sample size, it's no sample at all. It's politics, money, intangibles, longer-term considerations. There were equally good or even more deserving fringe relievers than Walker or Lorenzen last year too. And even having not thrown a relief pitch all year Walker likely would have pitched in a losing blowout. There just never was one. This year at least he's shown he can mop up or even staunch the bleeding occasionally.
I agree they should carry the extra bench guy, possibly throughout, but that also depends on the the way the rotation and schedule and opposing rotation looks when they get there.
