I don't really think Orf or Dubon (sounds like the injury is bad) are really starting caliber players in the bigs. They're probably both suitable bench players though so I wouldn't have an issue with Sogard getting replaced. I sorta get the feeling this weekend was Sogard's chance to get going and since he didn't he's at severe risk of losing his roster spot in the next week or so when Knebel, Logan, and Davies will all presumably be back. This team has an opportunity to make a meaningful upgrade to the roster at 2b. They're getting limited offensive production and pretty bad defense at the position. Neil Walker has been bad, but there is a decent chance he gets DFAd when Bird comes back. If he does, the Brewers should explore acquiring him. Beyond Walker, there are several 2b options who may become available before the trade deadline including Lowrie (personal preference), Schoop, Dozier, Cabrera, etc. Until they can upgrade the position, I would ride Villar at second base as much as possible since he's unfortunately the best option at the moment.
