Well Pollack, Duvall, etc. got more playing time and significant chunks of change with their respective new teams. We couldn't offer the former so it didn't make sense to spend the latter.
Whoever we sign will be battling it out with Whit Merrifield, Espinal, Biggio and others for ABs. We don't even have DH opportunities for whoever we sign. They'll basically be a 5th OFer.
Otto Lopez could handle that role just fine and he's also pretty fast and can play the infield too. Sounds like a good enough 5th OFer to me.
And injuries will of course happen, but that's when someone like Lukes can come into play. Or Barger, Capra, etc.
