Put me also in the ride it out camp. Royce is the type of talent that can carry a team. Yes, he is having a bad year, but I still don't believe he is fully healthy either. In the past few games you can see him grabbing at that hamstring and stretching it out at the plate. He does this weird front side flying open then clutching at his left hamstring.
The bigger problem is Wallner. He has a huge upside, but can't seem to put it together. Seems to have taken a few steps back at both the plate and in the field. Personally, I think we need to send him down or trade him. Not sure we would get a ton in return, but we do have log jam of corner OF (still have ERod, Jenkins, and McCusker). I know ERod left the game Saturday with another injury, but may be time to see what McCusker can do at the MLB level.
Personally I think our best lineup is Bader (LF), Buxton (CF), Castro (RF), Royce (3B), C4 (SS), Lee (2B), France or Clemmons (1B), Jeffers (C), and Larnach (DH).
