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. Cutting bait on Hoover so quickly surprises me, in a good way. It shows their faith in Williams, and that they are committed to putting the best talent on the field, even if it means sacrificing depth. Williams is still going to have to survive Yelich coming off the DL on Sunday, though. I suppose they could send out Guerra or Suter, though, and bring up a different guy next time they need a fifth starter.
