This will be Gomber's second start in place of Carlos Martinez in the rotation, and third overall. The rookie lefty has a 5.23 ERA in those starts and a 3.38 ERA as a reliever. He allowed four runs in four innings vs. the Pirates last time out.
Smith will open the I-70 Series for the Royals on Friday. The recent addition to the starting rotation struggled in his last start, allowing six runs over five innings on Saturday in Minnesota.
