Both Castellanos and Duvall have been over .900 vs LHPs since the start of 2017.
If we really want to boost the offense, 3 positions look to be in need, but only one looks weak on defense, too: 2B.
The possible return of Pedey might keep a move at 2B at bay for a while, but at some point, a decision may be needed on 2B.
Replacing JBJ has been a hot topic and has a thread all to itself. Trading for an OF'er or DH type and letting JD play more OF is certainly an option, even if just for a platoon OF'er who just kills lefties.
I don't see us trading for a catcher, and I've never heard Chirinos' name mentioned. He kills lefties, but I'm not sure about his defense.
I'm thinking we won't do anything too major. Maybe something like this:
Hembree, Johnson, Swihart, Beeks & Travis for Joakim Soria, cash and Avisail Garcia (OF who killes lefties). (I'm thinking they may deal Abreu elsewhere and might want Sam Travis.)
We'd probably have to get enough money to keep us under the max penalty line, unless we shed salary elsewhere (JBJ or Pom?).
