SURPRISE, Ariz. (AP) — The Royals added depth to their starting rotation Saturday by signing veteran right-hander Chris Young to an incentive-laden, one-year contract.

Young will make $675,000 in base salary, but he’s eligible for $1 million in roster bonuses based on active days on the roster. He is also eligible for $1.975 million in bonuses for innings pitched, and $2.35 million in bonuses for games pitched.

The 35-year-old Young was 12-9 with a 3.65 ERA for the Mariners last season. He was voted the American League’s comeback player of the year after missing most of the previous season because of surgery to correct a nerve issue in his neck and shoulder.

The Royals’ five-man starting rotation is largely set with Yordano Ventura, Edinson Volquez, Danny Duffy, Jeremy Guthrie and Jason Vargas.
