KANSAS CITY, Mo. (AP) — The Royals have announced the signing of right-hander Edinson Volquez to a $20 million, two-year contract that includes a mutual option for the 2017 season.

Volquez will make $7.5 million in 2015 and $9.5 million in 2016 under the deal announced Monday. His option year is worth $10 million with a $3 million buyout.

Volquez fills the last big hole by taking James Shields’ spot in the rotation. Shields became a free agent and it was unlikely the Royals would be able to keep him.

The Royals have already signed designated hitter Kendrys Morales and outfielder Alex Rios to fill two of their other pressing needs. They also signed pitcher Kris Medlen, who is rehabbing from Tommy John surgery and could help contribute midway through the season.
