I’m actually the rarest of the rare - a Rusney Castillo fan. But no, it’s Pawtucket. The Red Sox absolutely do need a fourth outfielder (and have yet to sign Notin recommendation and potential gem Cesar Puello), but I doubt it’s Rusney, strictly for financial reasons.
I’d take Lin over Holt. Same logic, plus Lin is good. I think he’s a better defender than Holt. And Holt might be slightly more versatile, but on a roster with Lin, Peraza and Chavis, this might not matter as much...
