Lyles will be the starting pitcher for Monday's game against the Pirates, Thomas Harding of MLB.com reports.
Lyles will get another chance to start due to the postponement of their matchup with the Pirates being moved to Monday. He was just called up from Triple-A Albuquerque on Friday and was expected to be a long reliever after a rough start to the year, which included a 7.64 ERA and 1.87 WHIP in four starts.
