Pretty sure the COVID IL rules are still in effect so a 40-man roster move is not needed now, but will be needed whenever Brogdon is ready again. And as one of only 3 bullpen pitchers we can currently trust, hopefully that will be soon.
They really should have called up Crouse on paper and put him on the 60-day list since he has been out that long. Damon Jones has to be in danger at some point. Though a glance at old friend Austin Davis' stats with the Red Sox does show one should never give up on a LHP that throws in the mid-90s.
