Keller signed a one-year, $5.775 million contract with the Royals on Friday to avoid arbitration, Robert Murray of FanSided.com reports.
Keller is coming off back-to-back dreadful seasons, even getting demoted to the bullpen at one point in 2022. The Royals will hope he can bounce back in his walk year and perhaps boost his value enough that they can flip him for a prospect at the trade deadline.
