In nine Cactus League innings, the 33-year-old Ohlendorf has allowed six runs, while striking out 10. An eight-year Major League veteran, Ohlendorf pitched for the Rangers in 2015, posting a 3-1 record with one save and a 3.72 ERA in 21 relief appearances.
Ohlendorf has been competing for a spot in the defending World Series champions' bullpen, one of the keys to the Royals' run to consecutive American League pennants.
