The Orioles placed Means on the Family Medical Emergency List on Sunday.
The transaction comes one day after Means tossed seven innings of one-run ball in a 7-1 win over the Rays, evening his record to 9-9 in the process. Means can spend between three and seven days on the Family Medical Emergency List before rejoining the club, putting his availability for his next start in jeopardy. Due to a pair of off days Monday and Thursday, the Orioles would have the luxury of getting by with a four-man rotation for the time being if Means requires the maximum amount of time off.
