I think they realize Drake and Hoover aren't world beaters. But as you said, Williams has options. Could be Barnes, but I doubt it. That's just the way it is, guys like Williams, Houser, etc. who have options will be shuttled back and forth. Like it or not, that flexibility really helps when you have minor injuries like this, need for a fresh arm in the BP, etc. It's basically a way to have an 11 man BP.
