Just for a year or so. Give our young guys time. We can also trade bullpen arms for someone. Lopez + Schroeder/Colome/Alabaldajeo = leadoff 2nd baseman. I like Iguchi for a short-term sign but he doesn't get on base.
There isn't anyone I can think of that makes sense. Castillo is too old. But really it doesn't have to be a Castillo type just someone that has a high OBP and can run faster than Schneider
