Manager Bob Melvin said Thursday that Kaprielian will transition to a bullpen role, Matt Kawahara of the San Francisco Chronicle reports.
Kaprielian was initially slated to start Saturday's game against the Angels, but Daulton Jefferies will take his place as the starter. The 27-year-old will attempt to right the ship in a relief role after he recorded an 8.10 ERA and 1.80 WHIP in 16.2 innings across his last four starts.
