I'd be fine with Gennett or Dietrich as a cheap stop gap 2B fill in, then bench piece. Neither has signed yet. But both hit lefty so neither would be a good platoonmate for Mazara down the line.
Sox could use someone that can cover 3B for a couple weeks. We really don't have anyone on the roster to cover 3B. I guess Leury could do it, but I don't think that'd be very pretty. Honestly, I kind of think the Sox resign Yolmer at this point on like a 1 year $3M deal.
