The Oakland Athletics have acquired left-hander Justin Marks from the Kansas City Royals for cash considerations.
The A's announced the deal Friday and said they optioned Marks to Triple-A Sacramento.
Oakland still must make a corresponding move to the 40-man roster.
The 26-year-old Marks went 3-2 with a 5.64 ERA in 13 appearances with two starts for Triple-A Omaha.
He posted a 3.42 ERA with 24 strikeouts in 26 1-3 innings in 11 relief outings.
Marks made his major league debut April 17 against Minnesota after being called up from the minors that day for a brief big league stint.
