Criswell will be called up to start Friday against the Padres, Kevin Acee of The San Diego Union-Tribune reports.
Criswell has made16 minor-league starts this season, most recently logging a 3.98 ERA and 27:6 K:BB across four outings with Triple-A Salt Lake. It will likely be a spot start for the right-hander, though a strong performance would go a long way to keeping him in the big leagues going forward.
