I am with you Austinfan. I just don't see a whole lot of upgrades that would be available out there this year.
RF: Williams and Altherr - Williams is starting to put it together.
Possible upgrades available - Castellanos, Detroit; McCutchen, San Fran; Rasario, Minnesota
McCutchen would cost the least as he is a free agent to be. Castellanos is controllable through 2019 and Rasario is first time arbitration eligible this year
3B: It's not like Kris Bryant is available. Is Matt Carpenter an upgrade? If Colorado goes on a loosing streak, you could see what Arenado would cost, but I don't see them trading him.
Bench: Valentin and Altherr could both be upgraded because right now Plouff is really your "weapon" on the bench.
The Phillies could look at Matt Duffy in Tampa, Billy Hamilton in Cincinnati (would be nice to have a speed threat) or Jankowski in San Diego
SS: Crawford has never really hit above AA ball and Kingery is playing out of position as a rookie. While it isn't ideal for Kingery to be playing SS - that could really screw with a kid to suddenly bench him, in spite of his low OBP. - And I am looking long term, not go for broke, because they are one player away from winning the WS this year. But I do like Salisbury's opinion of Escobar from Minnesota
Bullpen: Morgan's last few outings have been encouraging. Hunter, Rios, Neris and Leiter have been a disaster this year. Salisbury mentions Familia, but do you think the Mets would trade to an NL East rival? Adding Happ/Hamels or Britton would be a nice addition
