Quantrill (0-2) took the loss against the Pirates on Sunday, giving up five earned runs on eight hits over five innings, striking out two and walking two as the Padres fell 6-4.
Quantrill was called up from Triple-A El Paso to make this spot start and had a rough outing, with most of the damage coming on a three-run long ball he gave up to Colin Moran in the first inning. He had posted respectable stat lines in his other two big-league starts prior to this contest, and with Chris Paddack and Matt Strahm each having their workloads managed, Quantrill may continue to receive spot starts throughout the season.
