KANSAS CITY, Mo. (AP) -- Jason Hammel's $12 million mutual option has been declined by the Kansas City Royals, who will pay the 36-year-old right-hander a $2 million buyout.
Hammel set a career-high for losses, going 4-14 with a 6.02 ERA in 18 starts and 21 relief appearances. He was dropped from the rotation in early July after losing six straight starts.
He agreed to a $16 million, two-year contract before the 2017 season and went 12-27.
In other free agency news, former Royals third baseman Mike Moustakas will become a free agent after declining a $15 million mutual option on Tuesday from the Milwaukee Brewers.
Moustakas rejected a $17.4 million qualifying offer and left Kansas City after the 2017 season but was unable to find a long-term deal he liked. He returned to the Royals in mid-March for a one-year contract that included a guaranteed $6.5 million: a $5.5 million salary and $1 million option buyout.
A 30-year-old left-handed hitter, Moustakas had a .251 average with 28 homers and 95 RBIs. He hit .256 with eight homers and 33 RBIs in 54 games for Milwaukee, which acquired him from the last-place Royals on July 27.
Another former Royal in reliever Joakim Soria will also be hitting free agency.
Soria declined a $10 million mutual option and gets a $1 million buyout, completing a $25 million, three-year contract he agreed to with the Royals in December 2016. The right-hander was acquired from the Chicago White Sox on July 26 and was 3-1 with a 4.09 ERA in 26 games with the Brewers.
