Robertson was placed on the bereavement list ahead of Thursday's game against the Orioles, Scot Gregor of the Daily Herald reports.

EDGE Analysis

Robertson will have to miss a minimum of three games, ruling him out at least until Sunday. Nate Jones, Matt Albers and Zach Duke could all be in the mix for ninth-inning work while Robertson is away from the team. Meanwhile, infielder Carlos Sanchez was recalled from Triple-A Charlotte for the corresponding transaction.
