Christian Walker would be significantly better than Hoskins and Bauers but that is about it. Beyond Walker the next best available would be Alonso. I hope the Cardinals and Cubs continue to suck and stay under .500 so the Cardinals trade Goldschmidt to the Yankees and that leaves really only the Brewers looking for 1B help. Could make Walker attaining Walker or Alonso easier. The only other team I can think of that would need 1B help would probably be the Twins.
Alonso may not even be available because the NL Wild Card race looks like it is going to be whoever sucks the less right now for the final spot. Only the Rockies and Marlins right now look to be out of it with everyone else being 1-2 games out of the final wildcard spot. At some point some of these teams will go on a losing streak and someone will go on a winning streak. There will be some separation at some point just right now it is a cluster <insert your favorite four letter cuss word>.
Right now there are only 4 teams in the NL above .500 and one team at .500. That won't stay like that for the rest of the season but usually by now you can tell who will be sellers and who will be buyers and right now there are only four buyers and two definite sellers in the NL. Everyone else in the NL are just big question marks and some of these NL teams have what everyone else wants in a trade. The AL is a little bit better off but there are only three definite sellers and at least six definite buyers. The Red Sox, Blue Jays and Tigers all could be buyers or could be a mixture of both depending on what becomes available. I could see the Blue Jays or Red Sox trading for Luzardo even if they are out of it.
