I'm not necessarily opposed to a stopgap, but they have to be something more than serviceable. The problem is that I don't know who that would be. A long term solution would be nice since this team hasn't had a legit, long term solution for too long.
I'm still hoping that Martin can figure things out and help out at CF. That's obviously also not without risk.
Ideally, right now anyway, I think I'd move Urshela over to SS. Miranda to 3B. Kirilloff to 1B. At least there are more options for 1B than the left side of the infield. Leave Polanco at 2B.
