In the words of manager Kevin Cash, Andriese will "fill the gap" in Friday's home game against the Mariners in the wake of Chris Archer's placement on the disabled list with an abdominal injury, Bill Chastain of MLB.com reports.

What that phrase means exactly is a topic for debate. Andriese certainly could play the role of a traditional multi-inning starter, filling in for Archer in the starting rotation, or he could be brought in for an extended relief stint after the opening pitcher if Cash opts to go with a "bullpen day." The exact manner in which he'll be deployed may not become known until later in the week.
