CHICAGO — Jake Arrieta is returning to the Chicago Cubs, agreeing to a $6 million, one-year contract on Friday.

Arrieta can earn $1 million in performance bonuses, according to a person familiar with the situation who confirmed the deal on condition of anonymity because it is pending a physical.

The 34-year-old Arrieta won the NL Cy Young Award with Chicago in 2015 and helped the Cubs win the 2016 World Series for their first championship since 1908. He went 68-31 with a 2.73 ERA in 128 starts over five years in his first stint with the team.
