I think "appalling" is the correct adjective to describe Roman Quinn's current OBP, in the current season, which is half-over. It's inherently a small sample. The same is true of Cutch (and a stronger word than appalling would be needed to describe Kingery).
Fortunately our overall team offense is very strong, and Quinn and Kingery are at the bottom of the order where we've seen the likes of Freddy Galvis and Maikel Franco getting themselves out in the past, so not a big deal considering how much else Quinn brings to the line-up.
I think we can safely stipulate that Roman would be a great productive everyday player had he been able to stay healthy, and maybe he still will be. He may even defy the age curve for a bit, less wear on him.
