Bergman will start Friday against the Blue Jays, Bob Dutton of the Tacoma News Tribune reports.
With Hisashi Iwakuma (shoulder) hitting the DL on Wednesday, the M's now have four starters on the DL and will be forced to turn to Bergman for at least one turn in the rotation. Bergman allowed just one run over 3.2 innings out of the bullpen in his first appearance of the season, and he fared well with Triple-A Tacoma to begin the year, but the 29-year-old right-hander has enjoyed limited success at the major-league level (4.78 ERA away from Coors Field).
