I am really curious whether this is aall due to Martinez being an awful manager or just the team itself. With Straus down they've got only one single pitcher worth a damn, in my opinion, and the fact they didn't address one of the starting 5 in the Free Agency is ridiculous. Beyond that, while they've been hurt, this group of guys have struggled to hit with RISP for years now. Outside of periods where Rendon or Murphy got hot, they're just booty at it. It's a long ball club that generally does good when it's warm.
Maybe look into moving Harper right now and bringing in a starting pitcher or some more consistent hitters. I don't think they're that off from being a WC or playoff team quality wise but it doesn't matter if they still keep Harper on the roster. He's going to want big bucks no matter what and I doubt he wants to be here.
