Not exactly my wish. It just occurred to me when I posted that due to attrition another infielder would be needed. Mererro has been up before and was of little consequence.
I think that Farrell will stay with Rutlege at 3rd until he has a viable or hopefully better option. Mererro gives Farrel someone to sub for an infielder other than a 1st baseman and he can pinch run, etc. The team does need a bench to cover all positions. Not sure what he plans for 1st base with Hanley slotted for only DH and Holt supposedly on the mend in Portland.
Anyway, one plus from Mererro being brought up is his best Buddy relationship with Betts and Bradley. That may have some benefit as far as moral is concerned.
