The rotation pecking order beyond Sheets and Suppan to begin the season was Bush, Villanueva, Parra, in that order. The results of all 3 have been inconclusive. None has stepped out and made a strong case that he belongs above the other two. Therefore, assuming it's a starter that goes, my money is on Parra being optioned. That makes sense because Parra has the least major league experience of the three, and less AAA experience too. The Brewer website lists Villanueva as the starter on Monday, and "to be determined" Sunday and Tuesday. I figure they'll go with Yo Sunday, and just move back Bush to Tuesday. Before yesterday, I would have thought McClung was going to go. But 3 shutout innings saved him for now in my mind (and put Turnbow in real jeopardy). Stetter may or may not be a temporary callup, but I think they'd be a lot more comfortable sending down Parra if they had 2 lefties in the pen. That way Yost can have a quicker hook in games with teams having a stacked lineup of lefthanded hitters. Remember though it's still April. If either Parra or Villanueva goes down to Nashville, it's quite likely, even probable that whoever it is will be back at some point, sooner rather than later.
