Kyle Gibson (back) will throw a bullpen session on Saturday, and if all goes well he will make his next start on Tuesday against the Royals. He had been scheduled to start on Wednesday, but was scratched due to back stiffness. The 26-year-old owns an 8-8 record, 4.19 ERA, 1.28 WHIP and 54/30 K/BB ratio over 107 1/3 innings through his first 19 starts.
