(CBS) The White Sox have signed right-handed reliever Nate Jones to a three-year, $8-million deal, they announced Friday. The contract also includes club options for 2019 and 2020 with the two sides having a mutual option for 2021.

The 29-year-old Jones had a 3.32 ERA in 19 innings in 2015, not appearing until early August as he recovered from Tommy John surgery. Jones has a career 3.52 ERA.

“We view Nate as a key component in the back end of our bullpen,” general manager Rick Hahn said in a statement. “Nate is a homegrown pitcher with a power arm and tremendous work ethic, so we are excited to be able to reward him for what he has accomplished thus far in his career and potentially keep him in a White Sox uniform for the next six seasons.”

Jones will make $900,000 in 2016, $1.9 million in 2017 and $3.95 million in 2018. The club option is for $4.65 million in 2019 and $5.15 million in 2020, with a $6 million mutual option in 2021. The buyout if a club option is declined is $1.25 million.
